There is a paucity of information on their role in metastatic disease. The concept of the fourth column was described by Berg in 1993, and has been proven in case report, clinically and biomechanical studies. The role of the sternum as a support to the thoracic spine is well documented in the trauma patients, but not much is known about its role in cancer patients. This review examines what is known on the role of the fourth column. Following this we have identified two likely scenarios that sternal metastases may impact management:(1) sternal pathological fracture increases the mobility of the semi-rigid thorax with the loss of the biomechanical support of the sternum-rib-thoracic spine complex; and(2) a sternal metastasis increases the risk of fracture, and while being medical treated the thoracic spine should be monitored for acute kyphosis and neurological injury secondarily to the insufficiency of the fourth column.展开更多

Methods From January 2007 to January 2011, 14 patients with sternal tumors were admitted into Peking Union Medical Hospital. The clinical characteristics, surgical resection, and technique of reconstruction were reviewed. Results Of the 14 patients, 3 had a metastatic sternal tumor, the primary sites of which were as follows: hepatic carcinoma in one case (metastasis 19 years after operation), breast carcinoma in another case (metastasis 5 years after operation), and renal carcinoma in the other case (found simultaneously). Two patients showed local involvement of the sternum: 1 had thymic carcinoma, and the other had myofibrosarcoma. The remaining 9 patients had primary tumors: 4 were osteochondroma, 3 chondrosarcoma, 1 eosinophilic granuloma, 1 non-Hodgekin's lymphoma. En bloc resection of the sternal tumor was performed in all the 14 patients. The defect was repaired with the titanium mesh adjusted to the shape of the defect and fixed with the stainless steel wire. Eleven patients were followed up for a period from 2 months to 4 years, during which no translocation or broken of the titanium mesh was observed. Conclusions Radical en bloc excision remains the treatment of choice for sternal tumors. Sternum defect reconstruction using titanium mesh as a rigid replacement proves appropriate and effective.展开更多

Methods Between January ...Objective To assess clinical effectiveness of using bilateral pectoralis major or plus rectus abdominis muscle flaps in treating deep sternal wound infection(DSWI) following median sternotomy. Methods Between January 2009 and December 2013, 19 patients with DSWI after median sternotomy for cardiac surgery were admitted to our hospital, including 14 males(73.7%) and 5 females(26.3%), aged 55±13(18-78) years. According to the Pairolero classification of infected median sternotomies, 3(15.8%) patients were type II, and the other 16(84.2%) were type III. Surgical procedure consisted of adequate debridement of infected sternum, costal cartilage, granulation, steel wires, suture residues and other foreign substances. Sternal reconstruction used the bilateral pectoralis major or plus rectus abdominis muscle flaps to obliterate dead space. The drainage tubes were placed and connected to a negative pressure generator for adequate drainage. Results There were no intraoperative deaths. In 15 patients(78.9%), bilateral pectoral muscle flaps were mobilized sufficiently to cover and stabilize the defect created by wound debridement. 4 patients(21.0%) needed bilateral pectoral muscle flaps plus rectus abdominis muscle flaps because their pectoralis major muscle flaps could not reach the lowest portion of the wound. 2 patients(10.5%) presented with subcutaneous infection, and 3 patients(15.8%) had hematoma. They recovered following local debridement and medication. 17 patients(89.5%) were examined at follow-up 12 months later, all healed and having stable sternum. No patients showed infection recurrence during the follow-up period over 12 months. Conclusion DSWI following median sternotomy may be effectively managed with adequate debridement of infected tissues and reconstruction with bilateral pectoralis major muscle or plus rectus abdominis muscle flap transposition.展开更多

This condition leads to mediastinitis. Mediastinitis is a serious condition which increases morbidity, mortality and hospital costs. The correct time for surgical treatment is contraversial in cases who have sternal dehiscence and discharge due to superficial infection. In this study, patients received sternal stabilization as soon as a diagnosis was made and monitored for the development of mediastinitis. Methods: Among the 1440 patients who had undergone elective CABG, a total of 85 patients who developed sternal dehiscence and superficial wound discharge were included in this study. These patients were re-operated on as soon as diagnosed and early sternal stabilization was provided. Results: The ratio of overall dehiscence was 5.9%. Mediastinitis developed in only 2 of the 85 patients. These patients were treated with VAC (Vacuum Assisted Closure) therapy. The ratio of overall mediastinitis was 0.13. Mediastinitis-related mortality was not detected. Conclusion: The ratio of mediastinitis decreases when patients who have discharge due to sternal dehiscence and superficial wound infection are immediately reviewed without waiting for the results of conventional methods such as antibiotic treatment and chest binder support.展开更多

Despite ad-vances in many areas of cardiac surgical procedures, there is a lack of innovation in sternal closure techniques. Several studies have examined sternal closure techniques including wiring, interlocking, plate and screw, and bone cementation. However, none of them achieved widespread acceptability. On one hand, serious post-operative complications are associated with the use of wiring and plating techniques in high-risk patients. The aim of this study is showing challenges and difficulties with resternotomy in patient with a history of previous cardiac surgery and usage of biologic bone cements. Case Report: The case was a 56-year-old woman with a history of previous sternotomy for mitral and aortic valve replacement (mechanical sj. No. 29 and mechanical sj. No. 21, respectively) using biologic bone cement (Kryptonite TM, Doctors Research Group Inc.) for her osteopenic sternum. Four years after the mitral valve replacement (MVR), she was referred to emergency department with a thrombosis at the mitral valve. She under-went emergent cardiac surgery with a very difficult resternotomy under femoral cannulation support. Conclusion: Resternotomy in patients with previous sternotomy with Kryptonite bone cements or calcium phosphate cements (CPC) is safe and can be done similar to other cardiac reoperations. It seems that reoperation in this patients does not increase the risk of bleeding, morbidity, and mortality.展开更多

We are reporting a patient with sternal dehiscence after coronary artery bypass surgery that underwent application of thermoreactive nitinol clips in addition to Robicsek procedure. Using thermoreactive nitinol clips method together with Robicsek procedure may be a valuable technique for preventing recurrent sternal dehiscence for patients who are candidates of noninfective recurrent sternal dehiscence.展开更多

NPWTi accelerates wound healing through macrostrain, microstrain, and cyclic fluid instillation. Wounds benefit from additional superficial infection control with the removal of microorganisms, the release of proinflammatory mediators, stimulation of angiogenesis, as well as mechanical debridement. However, very few cases of utilizing NPWTi in the treatment of sternal wound infections have been reported in the literature. This case study describes the use of NPWTi with hypochlorous acid for the treatment of a sternal wound infection.展开更多

It＇s very difficult to treat DSWI, and there is lack of agreement regarding the best therapy strategy. Thus, we aimed to summarize our experiences of surgical treatment for DSWI, in which satisfactory clinical results were obtained. Methods We retrospectively analyzed 17 cases who suffered from DSWI after cardiac surgery in our department from January 2010 to June 2015. There were 8 male and 9 female patients with their average age of 62.7 ___ 9.5 years （range 42 ~ 75 years）. All patients re- ceived reservation of part of sternum combined with vacuum-assisted suction drainage and bilateral pectoralis ma- jor myocutaneous advancement flaps. Results The average interval between cardiac surgery and diagnosed DSWI was 10.9 ± 6.5 days （range 5 - 21 days）. Time of vacuum-assisted suction drainage was 11.6±4.8 days （range 5 - 15 days） and wound healing time was 27.3 ± 7.2 days （range 23 - 35 days）. All patients had an uneventful postoperative recovery and good wound healing. Follow-up time was 33.7 _ 13.3 months （range 8 74 months）. No recurrent infection was observed. Conclusions Reservation of part of sternum combined with vacuum-assisted suction drainage and bilateral pectoralis major myocutaneous advancement flaps is a simple and effective surgical strategy for the treatment of DSWI after cardiac surgery.展开更多

This prospective study aimed to assess our management of DSWI in view of the published literature. Methods: Over 2-years (ending in January 2016), 29 patients (20 males) developed DSWI amongst 520 patients who underwent standard CABG surgeries (5.6%). Pre-, intra- and postoperative variables were documented. Whenever possible, the infections were culture-verified. Besides antibiotics, patients received one or more of the following therapies: drainage, debridement, closed irrigation, sternal re-wiring, vacuum-assisted closure (VAC), and bone resection. Results: the male to female ratio was 2.2:1. Mean age was 58.1 ± 7.3 years. The mean body mass index (BMI) was 27.9 ± 3.4 kg/m<sup>2</sup>. There were 18, 16 and 11 patients with diabetes mellitus (DM), hypertension and chronic obstructive pulmonary disease (COPD) respectively. Cardiopulmonary bypass (CPB) was utilized in 26 (89.7%) patients with a mean time of 117.5 ± 23.3 minutes. Most surgeries (n = 21, 72.4%) lasted 5 - 6 hrs. According to Pairolero classification, there were 3 (10.3%) Type I, 22 (75.9%) Type II and 4 (13.8%) Type III infections. Four (13.8%) cases were culture-verified. Twenty-three (79.3%) DSWIs were surgically managed. Sternal re-wiring was performed in 14 (48.3%) cases while VAC was added to other therapies in 2 (6.9%) patients. DSWIs completely resolved in 18 (62.0%) patients within 3 - 24 weeks while two (6.9%) patients died within 30 days. Conclusion: We have identified six independent risk factors for DSWI (male gender, obesity, DM, hypertension, COPD and CPB), five of them are modifiable.展开更多

However, sternal wound complication (SWC) remains challenging following the procedure. The technique of left internal mammary artery (LIMA) harvesting has been shown to impact the incidence of SWC. This study aimed to compare the incidence of SWC between two techniques of LIMA harvesting, i.e., skeletonized and pedicled. Methods: The study was conducted at the Department of Cardiac Surgery, Bangabandhu Sheikh Mujib Medical University, and included 60 patients who underwent OPCAB. The patients were divided into two groups of 30 each based on the technique of LIMA harvesting used, i.e., skeletonized (group A) or pedicled (group B). The postoperative ICU care was given to each patient as per the protocol. The statistical analysis was conducted using the SPSS version 26.0 for Windows software. Results: The results showed that 5 (8.33%) patients developed SWC, with 1 (1.67%) patient in group A and 4 (6.66%) patients in group B. However, the occurrence of SWC was not statistically significant between the two groups (p = 0.35). The mean age, gender distribution, and comorbidities such as hypertension, diabetes, dyslipidemia, and anemia were also not statistically significant between the two groups. The number of smokers was statistically significant between the two groups (p = 0.03), and the occurrence of SWC was found to be higher in smoker patients in group B (p = 0.04). Preoperative and postoperative parameters such as duration of operation, duration of mechanical ventilation, duration of chest drains, duration of the central venous line, and amount of postoperative mediastinal bleeding were also not statistically significant between the two groups. The distribution of wound complications, duration of ICU stays, and hospital stay between the two groups was also not statistically significant. Conclusion: In conclusion, this study found that the incidence of SWC was less in skeletonized LIMA harvesting than in pedicled LIMA harvesting after OPCAB. However, this finding was not statistically significant. Further studies with larger sample sizes may be needed to confirm these results and determine the appropriate technique of LIMA harvesting to decrease the incidence of SWC after OPCAB.展开更多

Approximately 7% of these goitres which require surgical resection will need an additional sternotomy to deliver the intra-thoracic component. Massive retrosternal toxic goitres presenting acutely are rare and are described infrequently in literature. We hereby present two cases of massive retrosternal thyrotoxic goitres presenting with acute respiratory failure, requiring non-invasive ventilation, as well as significant head and neck venous compression. Surgery on the thyrotoxic patient with a goitre, even if not significantly enlarged, is associated with a high peri-operative mortality due to cardiac instability and hemorrhage. We discuss the challenges of surgical intervention in these patients with particular emphasis on the timing of surgery to relieve compressive symptoms and the time needed to achieve a euthyroid state. We also emphasize the need for meticulous hemostasis, use of a cell-saver, transfusion protocols, adjuncts to hemostasis, as well as careful monitoring and continuous adjustments to the coagulation profile.展开更多

International guidelines are vague: French guidelines recommend an intraoperative administration, while the Society of Thoracic Surgeons’ guidelines suggest that optimal postoperative prophylactic antibiotics be given for 48 hours or less. Very few studies have compared the same antibiotic with 2 different administration durations. The study was designed to compare the efficacy of 24-hour administration of cefamandole vs intraoperative cefamandole to prevent deep sternal wound infection and endocarditis after cardiac surgery. Methods: This retrospective and observational study compared the rates of severe surgical site infections (deep sternal wound infection, endocarditis) after cardiac surgery between period 1, 01/01/2008-31/08/2008, with 24-hour administration of cefamandole, and period 2, 01/09/2008-30/04/2009 with intraoperative cefamandole. Results: Among 933 patients, 14 patients (1.5%) developed surgical site infection during the 16-month study: 1.3% during the first period and 1.7% during the second (ns). The populations (470 patients in period 1 and 463 in period 2) were homogeneous and comparable for pre-, intra- and postoperative characteristics. Surgical site infection characteristics (pathogens involved, time to diagnosis) and consequences (longer hospital stay, outcomes) were comparable in the 2 groups. Conclusions: Intraoperative cefamandole was as safe as its 24-hour administration to prevent deep sternal wound infection and endocarditis after adult cardiac surgery.展开更多

This study aimed to assess clinical effectiveness of bilateral pectoralis major muscle flaps （BPMMF） for management of sternal osteomyelitis and mediastinal infection following median sternotomy.Methods Clinical data were collected and retrospectively analyzed from twelve patients who underwent the BPMMF transposition for management of sternal osteomyelitis and mediastinal infection following median sternotomy from January 2006 to June 2009. Procedure consisted of rigorous debridement of necrotic tissues, dead space obliteration using the BPMMF, and placement of drainage tubes connected to a negative pressures generator for adequate drainage.Results No patients died of drainage, and all 12 patients had viable BPMMF when discharged from hospital. At 1 week post discharge, 2 patients presented with sternal infection but recovered following local debridement and medication. No patients showed infection recurrence during the follow-up period over 10 months.Conclusions Sternal osteomyelitis and mediastinal infection following median sternotomy may be effectively managed through rigorous debridement of infected soft tissues, resection of the damaged stermal segment, transposition of the BPMMF to fill the damaged sternum resulting from debridement, and adequate postoperative drainage.展开更多

文摘Sternal metastases are not studied extensively in the literature. There is a paucity of information on their role in metastatic disease. The concept of the fourth column was described by Berg in 1993, and has been proven in case report, clinically and biomechanical studies. The role of the sternum as a support to the thoracic spine is well documented in the trauma patients, but not much is known about its role in cancer patients. This review examines what is known on the role of the fourth column. Following this we have identified two likely scenarios that sternal metastases may impact management:(1) sternal pathological fracture increases the mobility of the semi-rigid thorax with the loss of the biomechanical support of the sternum-rib-thoracic spine complex; and(2) a sternal metastasis increases the risk of fracture, and while being medical treated the thoracic spine should be monitored for acute kyphosis and neurological injury secondarily to the insufficiency of the fourth column.
文摘Objective To evaluate the use of titanium mesh reconstruction after sternal tumor resection. Methods From January 2007 to January 2011, 14 patients with sternal tumors were admitted into Peking Union Medical Hospital. The clinical characteristics, surgical resection, and technique of reconstruction were reviewed. Results Of the 14 patients, 3 had a metastatic sternal tumor, the primary sites of which were as follows: hepatic carcinoma in one case (metastasis 19 years after operation), breast carcinoma in another case (metastasis 5 years after operation), and renal carcinoma in the other case (found simultaneously). Two patients showed local involvement of the sternum: 1 had thymic carcinoma, and the other had myofibrosarcoma. The remaining 9 patients had primary tumors: 4 were osteochondroma, 3 chondrosarcoma, 1 eosinophilic granuloma, 1 non-Hodgekin's lymphoma. En bloc resection of the sternal tumor was performed in all the 14 patients. The defect was repaired with the titanium mesh adjusted to the shape of the defect and fixed with the stainless steel wire. Eleven patients were followed up for a period from 2 months to 4 years, during which no translocation or broken of the titanium mesh was observed. Conclusions Radical en bloc excision remains the treatment of choice for sternal tumors. Sternum defect reconstruction using titanium mesh as a rigid replacement proves appropriate and effective.
文摘Objective To assess clinical effectiveness of using bilateral pectoralis major or plus rectus abdominis muscle flaps in treating deep sternal wound infection(DSWI) following median sternotomy. Methods Between January 2009 and December 2013, 19 patients with DSWI after median sternotomy for cardiac surgery were admitted to our hospital, including 14 males(73.7%) and 5 females(26.3%), aged 55±13(18-78) years. According to the Pairolero classification of infected median sternotomies, 3(15.8%) patients were type II, and the other 16(84.2%) were type III. Surgical procedure consisted of adequate debridement of infected sternum, costal cartilage, granulation, steel wires, suture residues and other foreign substances. Sternal reconstruction used the bilateral pectoralis major or plus rectus abdominis muscle flaps to obliterate dead space. The drainage tubes were placed and connected to a negative pressure generator for adequate drainage. Results There were no intraoperative deaths. In 15 patients(78.9%), bilateral pectoral muscle flaps were mobilized sufficiently to cover and stabilize the defect created by wound debridement. 4 patients(21.0%) needed bilateral pectoral muscle flaps plus rectus abdominis muscle flaps because their pectoralis major muscle flaps could not reach the lowest portion of the wound. 2 patients(10.5%) presented with subcutaneous infection, and 3 patients(15.8%) had hematoma. They recovered following local debridement and medication. 17 patients(89.5%) were examined at follow-up 12 months later, all healed and having stable sternum. No patients showed infection recurrence during the follow-up period over 12 months. Conclusion DSWI following median sternotomy may be effectively managed with adequate debridement of infected tissues and reconstruction with bilateral pectoralis major muscle or plus rectus abdominis muscle flap transposition.
文摘Background: Discharge due to superficial wound infection and sternal dehiscence are the common complications of median sternotomy. This condition leads to mediastinitis. Mediastinitis is a serious condition which increases morbidity, mortality and hospital costs. The correct time for surgical treatment is contraversial in cases who have sternal dehiscence and discharge due to superficial infection. In this study, patients received sternal stabilization as soon as a diagnosis was made and monitored for the development of mediastinitis. Methods: Among the 1440 patients who had undergone elective CABG, a total of 85 patients who developed sternal dehiscence and superficial wound discharge were included in this study. These patients were re-operated on as soon as diagnosed and early sternal stabilization was provided. Results: The ratio of overall dehiscence was 5.9%. Mediastinitis developed in only 2 of the 85 patients. These patients were treated with VAC (Vacuum Assisted Closure) therapy. The ratio of overall mediastinitis was 0.13. Mediastinitis-related mortality was not detected. Conclusion: The ratio of mediastinitis decreases when patients who have discharge due to sternal dehiscence and superficial wound infection are immediately reviewed without waiting for the results of conventional methods such as antibiotic treatment and chest binder support.
文摘Congenital sternal foramen is an anomaly whose occurrence is rare in human but is especially unusual in animals.This defect was formed when fusion of multiple ossification centers was incomplete.It may be associated with other lesions in body organs especially cardiac anomalies.In the present study,we report a very rare case of congenital sternal foramen in a Holstein calf.The oval defect was like a gunshot wound and located at the lower third of the sternum.Apparently,the rest of skeleton system seems normal.The awareness of the anomaly is important for better diagnosis and treatment of diseases.
文摘Background: Median sternotomy and resternotomy is the standard technique for coronary artery bypass grafting (CABG), valvular heart disease, and congenital heart disease. Despite ad-vances in many areas of cardiac surgical procedures, there is a lack of innovation in sternal closure techniques. Several studies have examined sternal closure techniques including wiring, interlocking, plate and screw, and bone cementation. However, none of them achieved widespread acceptability. On one hand, serious post-operative complications are associated with the use of wiring and plating techniques in high-risk patients. The aim of this study is showing challenges and difficulties with resternotomy in patient with a history of previous cardiac surgery and usage of biologic bone cements. Case Report: The case was a 56-year-old woman with a history of previous sternotomy for mitral and aortic valve replacement (mechanical sj. No. 29 and mechanical sj. No. 21, respectively) using biologic bone cement (Kryptonite TM, Doctors Research Group Inc.) for her osteopenic sternum. Four years after the mitral valve replacement (MVR), she was referred to emergency department with a thrombosis at the mitral valve. She under-went emergent cardiac surgery with a very difficult resternotomy under femoral cannulation support. Conclusion: Resternotomy in patients with previous sternotomy with Kryptonite bone cements or calcium phosphate cements (CPC) is safe and can be done similar to other cardiac reoperations. It seems that reoperation in this patients does not increase the risk of bleeding, morbidity, and mortality.
文摘Postopereative sternal dehiscence is one of the most important complications of median sternotomy which may cause pulmonary dysfunction and mediastinitis. We are reporting a patient with sternal dehiscence after coronary artery bypass surgery that underwent application of thermoreactive nitinol clips in addition to Robicsek procedure. Using thermoreactive nitinol clips method together with Robicsek procedure may be a valuable technique for preventing recurrent sternal dehiscence for patients who are candidates of noninfective recurrent sternal dehiscence.

文摘A 53-year-old man with bleeding from a sternal mass associated with a toxic syndrome. Computed tomography (CT) revealed a destructive sternal mass, bilateral pleural effusion and an endobronchial lesion in the right middle lobe bronchus. Immunohistopathological study of an incisional biopsy confirmed metastasic lung adenocarcinoma.
文摘Utilization of negative pressure wound therapy with instillation (NPWTi) for sternal dehiscence wounds secondary to sternal wound infection after surgery has become an accepted therapy. NPWTi accelerates wound healing through macrostrain, microstrain, and cyclic fluid instillation. Wounds benefit from additional superficial infection control with the removal of microorganisms, the release of proinflammatory mediators, stimulation of angiogenesis, as well as mechanical debridement. However, very few cases of utilizing NPWTi in the treatment of sternal wound infections have been reported in the literature. This case study describes the use of NPWTi with hypochlorous acid for the treatment of a sternal wound infection.

文摘Background Deep sterna wound infection （DSWI） after median sternotomy for cardiac surgery is one of the most complex and potentially life-threatening complications. It＇s very difficult to treat DSWI, and there is lack of agreement regarding the best therapy strategy. Thus, we aimed to summarize our experiences of surgical treatment for DSWI, in which satisfactory clinical results were obtained. Methods We retrospectively analyzed 17 cases who suffered from DSWI after cardiac surgery in our department from January 2010 to June 2015. There were 8 male and 9 female patients with their average age of 62.7 ___ 9.5 years （range 42 ~ 75 years）. All patients re- ceived reservation of part of sternum combined with vacuum-assisted suction drainage and bilateral pectoralis ma- jor myocutaneous advancement flaps. Results The average interval between cardiac surgery and diagnosed DSWI was 10.9 ± 6.5 days （range 5 - 21 days）. Time of vacuum-assisted suction drainage was 11.6±4.8 days （range 5 - 15 days） and wound healing time was 27.3 ± 7.2 days （range 23 - 35 days）. All patients had an uneventful postoperative recovery and good wound healing. Follow-up time was 33.7 _ 13.3 months （range 8 74 months）. No recurrent infection was observed. Conclusions Reservation of part of sternum combined with vacuum-assisted suction drainage and bilateral pectoralis major myocutaneous advancement flaps is a simple and effective surgical strategy for the treatment of DSWI after cardiac surgery.
文摘Background: Deep sternal wound infection (DSWI), or mediastinitis, is a devastating complication of coronary artery bypass grafting (CABG). This prospective study aimed to assess our management of DSWI in view of the published literature. Methods: Over 2-years (ending in January 2016), 29 patients (20 males) developed DSWI amongst 520 patients who underwent standard CABG surgeries (5.6%). Pre-, intra- and postoperative variables were documented. Whenever possible, the infections were culture-verified. Besides antibiotics, patients received one or more of the following therapies: drainage, debridement, closed irrigation, sternal re-wiring, vacuum-assisted closure (VAC), and bone resection. Results: the male to female ratio was 2.2:1. Mean age was 58.1 ± 7.3 years. The mean body mass index (BMI) was 27.9 ± 3.4 kg/m<sup>2</sup>. There were 18, 16 and 11 patients with diabetes mellitus (DM), hypertension and chronic obstructive pulmonary disease (COPD) respectively. Cardiopulmonary bypass (CPB) was utilized in 26 (89.7%) patients with a mean time of 117.5 ± 23.3 minutes. Most surgeries (n = 21, 72.4%) lasted 5 - 6 hrs. According to Pairolero classification, there were 3 (10.3%) Type I, 22 (75.9%) Type II and 4 (13.8%) Type III infections. Four (13.8%) cases were culture-verified. Twenty-three (79.3%) DSWIs were surgically managed. Sternal re-wiring was performed in 14 (48.3%) cases while VAC was added to other therapies in 2 (6.9%) patients. DSWIs completely resolved in 18 (62.0%) patients within 3 - 24 weeks while two (6.9%) patients died within 30 days. Conclusion: We have identified six independent risk factors for DSWI (male gender, obesity, DM, hypertension, COPD and CPB), five of them are modifiable.
文摘Background: Off-pump coronary artery bypass grafting (OPCAB) is a surgical procedure that has gained popularity due to its potential benefits over traditional coronary artery bypass grafting, including reduced morbidity and mortality. However, sternal wound complication (SWC) remains challenging following the procedure. The technique of left internal mammary artery (LIMA) harvesting has been shown to impact the incidence of SWC. This study aimed to compare the incidence of SWC between two techniques of LIMA harvesting, i.e., skeletonized and pedicled. Methods: The study was conducted at the Department of Cardiac Surgery, Bangabandhu Sheikh Mujib Medical University, and included 60 patients who underwent OPCAB. The patients were divided into two groups of 30 each based on the technique of LIMA harvesting used, i.e., skeletonized (group A) or pedicled (group B). The postoperative ICU care was given to each patient as per the protocol. The statistical analysis was conducted using the SPSS version 26.0 for Windows software. Results: The results showed that 5 (8.33%) patients developed SWC, with 1 (1.67%) patient in group A and 4 (6.66%) patients in group B. However, the occurrence of SWC was not statistically significant between the two groups (p = 0.35). The mean age, gender distribution, and comorbidities such as hypertension, diabetes, dyslipidemia, and anemia were also not statistically significant between the two groups. The number of smokers was statistically significant between the two groups (p = 0.03), and the occurrence of SWC was found to be higher in smoker patients in group B (p = 0.04). Preoperative and postoperative parameters such as duration of operation, duration of mechanical ventilation, duration of chest drains, duration of the central venous line, and amount of postoperative mediastinal bleeding were also not statistically significant between the two groups. The distribution of wound complications, duration of ICU stays, and hospital stay between the two groups was also not statistically significant. Conclusion: In conclusion, this study found that the incidence of SWC was less in skeletonized LIMA harvesting than in pedicled LIMA harvesting after OPCAB. However, this finding was not statistically significant. Further studies with larger sample sizes may be needed to confirm these results and determine the appropriate technique of LIMA harvesting to decrease the incidence of SWC after OPCAB.
文摘BACKGROUND Delayed sternal closure(DSC)can be a lifesaving approach for certain patients who have undergone cardiac surgery.The value of the type of prophylactic antibiotics in DSC is still debatable.AIM To investigate clinical outcomes of different prophylactic antibiotic regimens in patients who had DSC after cardiac surgery.METHODS This was a retrospective observational single-center study.Fifty-three consecutive patients who underwent cardiac surgery and had an indication for DSC were included.Patients were subjected to two regimens of antibiotics:Narrow-spectrum and broad-spectrum regimens.RESULTS The main outcome measures were length of hospital and intensive care unit(ICU)stay,duration of mechanical ventilation,and mortality.Of the 53 patients,12(22.6%)received narrow-spectrum antibiotics,and 41(77.4%)received broad-spectrum antibiotics.The mean age was 59.0±12.1 years,without significant differences between the groups.The mean duration of antibiotic use was significantly longer in the broad-spectrum than the narrowspectrum group(11.9±8.7 vs 3.4±2.0 d,P<0.001).The median duration of open chest was 3.0(2.0-5.0)d for all patients,with no difference between groups(P=0.146).The median duration of mechanical ventilation was significantly longer in the broad-spectrum group[60.0(Δinterquartile range(IQR)170.0)h vs 50.0(ΔIQR 113.0)h,P=0.047].Similarly,the median length of stay for both ICU and hospital were significantly longer in the broadspectrum group[7.5(ΔIQR 10.0)d vs 5.0(ΔIQR 5.0)d,P=0.008]and[27.0(ΔIQR 30.0)d vs 19.0(ΔIQR 21.0)d,P=0.031].Five(9.8%)patients were readmitted to the ICU and 18(34.6%)patients died without a difference between groups.CONCLUSION Prophylactic broad-spectrum antibiotics did not improve clinical outcomes in patients with DSC post-cardiac surgery but was associated with longer ventilation duration,length of ICU and hospital stays vs narrow-spectrum antibiotics.
文摘Approximately 5% of goitres extend below the thoracic inlet and can potentially become life threatening due to compression of the airway and major vessels. Approximately 7% of these goitres which require surgical resection will need an additional sternotomy to deliver the intra-thoracic component. Massive retrosternal toxic goitres presenting acutely are rare and are described infrequently in literature. We hereby present two cases of massive retrosternal thyrotoxic goitres presenting with acute respiratory failure, requiring non-invasive ventilation, as well as significant head and neck venous compression. Surgery on the thyrotoxic patient with a goitre, even if not significantly enlarged, is associated with a high peri-operative mortality due to cardiac instability and hemorrhage. We discuss the challenges of surgical intervention in these patients with particular emphasis on the timing of surgery to relieve compressive symptoms and the time needed to achieve a euthyroid state. We also emphasize the need for meticulous hemostasis, use of a cell-saver, transfusion protocols, adjuncts to hemostasis, as well as careful monitoring and continuous adjustments to the coagulation profile.
文摘Background and Objectives: Duration of antibiotic prophylaxis for cardiac surgery is still debated and controversial. International guidelines are vague: French guidelines recommend an intraoperative administration, while the Society of Thoracic Surgeons’ guidelines suggest that optimal postoperative prophylactic antibiotics be given for 48 hours or less. Very few studies have compared the same antibiotic with 2 different administration durations. The study was designed to compare the efficacy of 24-hour administration of cefamandole vs intraoperative cefamandole to prevent deep sternal wound infection and endocarditis after cardiac surgery. Methods: This retrospective and observational study compared the rates of severe surgical site infections (deep sternal wound infection, endocarditis) after cardiac surgery between period 1, 01/01/2008-31/08/2008, with 24-hour administration of cefamandole, and period 2, 01/09/2008-30/04/2009 with intraoperative cefamandole. Results: Among 933 patients, 14 patients (1.5%) developed surgical site infection during the 16-month study: 1.3% during the first period and 1.7% during the second (ns). The populations (470 patients in period 1 and 463 in period 2) were homogeneous and comparable for pre-, intra- and postoperative characteristics. Surgical site infection characteristics (pathogens involved, time to diagnosis) and consequences (longer hospital stay, outcomes) were comparable in the 2 groups. Conclusions: Intraoperative cefamandole was as safe as its 24-hour administration to prevent deep sternal wound infection and endocarditis after adult cardiac surgery.

文摘Background:Sternal osteomyelitis is an infectious disease often secondary to median sternotomy and is characterized by high treatment difficulty,prolonged hospitalization,and substantial medical costs.The use of antimicrobial agents is a consensus and critical component in managing sternal osteomyelitis.To guide the rational use of antibiotics and provide a microbiological basis for diagnosis and treatment,this study investigates the distribution of pathogenic bacteria and their drug resistance patterns in sternal osteomyelitis patients at a tertiary medical center.Methods:A retrospective analysis was conducted on 205 cases(248 admissions)of sternal osteomyelitis patients admitted from January 2021 to June 2024.Their clinical data,microbiological culture results,and antimicrobial resistance patterns were collected and analyzed.Results:A total of 862 specimens of secretions,bone marrow,blood,and tissue specimens were collected,with a pathogen detection rate of 19.03%.Among these microorganisms,105 strains of gram-positive bacteria(64.02%),48 strains of gramnegative bacteria(29.27%),and 11 strains of fungi(6.71%)were detected.Staphylococcus aureus was the most common pathogen species.Multidrug resistance was confirmed in 38(46.34%)strains of gram-positive bacteria and 9(25.00%)strains of gramnegative bacteria.Conclusions:Sternal osteomyelitis patients are mainly infected by gram-positive bacteria,among which antimicrobial resistance is common.Strict adherence to sampling standards and appropriate use of antibiotics based on antibiotic susceptibility test results is essential.
文摘Background Median sternotomy is considered the most usually performed procedure in cardiac operations. This study aimed to assess clinical effectiveness of bilateral pectoralis major muscle flaps （BPMMF） for management of sternal osteomyelitis and mediastinal infection following median sternotomy.Methods Clinical data were collected and retrospectively analyzed from twelve patients who underwent the BPMMF transposition for management of sternal osteomyelitis and mediastinal infection following median sternotomy from January 2006 to June 2009. Procedure consisted of rigorous debridement of necrotic tissues, dead space obliteration using the BPMMF, and placement of drainage tubes connected to a negative pressures generator for adequate drainage.Results No patients died of drainage, and all 12 patients had viable BPMMF when discharged from hospital. At 1 week post discharge, 2 patients presented with sternal infection but recovered following local debridement and medication. No patients showed infection recurrence during the follow-up period over 10 months.Conclusions Sternal osteomyelitis and mediastinal infection following median sternotomy may be effectively managed through rigorous debridement of infected soft tissues, resection of the damaged stermal segment, transposition of the BPMMF to fill the damaged sternum resulting from debridement, and adequate postoperative drainage.
文摘Objective To describe our experience in the treatment of pectus excavatum(PE)using a modifed stemal elevation procedure.Methods From Oct.1986 to Dec.1997,171 patients with PE were admitted to the Department of Pediatric Surgery of the First Hospital of West China University of Medical Sciences.All patients were diagnosed through a history and physical examination.Cardiopulmonary function was assessed by M-mode echocardicgraphy and instrument of pulmonary function in 40 patients before and 4.2 years after surgery which was performed between 1989 and 1994.We performed the following three procedures in the stemal elevation:(1)forming the metal strut in a“arch”shape,(2)suturing the perichondrium into a“pipe”shape,and(3)encouraging patients to do chest expansion exercise after operation.All patients were followed up for 1 to 12 years.Results The normal contour of the costal cage was enlarged in all but one patient.Exercise tolerance was improved,and cardiac function recovered to the same level as in healthy children,while pulmonary function recovered very slowly after surgery.Conclusion The normal appearance of chest wall can be recovered and normal cardiopulmonary function can be restored by the modified stemal elevation procedure in children with PE

文摘Background:Diagnosing sternal wound infection(SWI)following median sternotomy remains laborious and troublesome,resulting in high mortality rates and great harm to patients.Early intervention and prevention are critical and challenging.This study aimed to develop a simple risk prediction model to identify high-risk populations of SWI and to guide examination programs and intervention strategies.Methods:A retrospective analysis was conducted on the clinical data obtained from 6715 patients who underwent median sternotomy between January 2016 and December 2020.The least absolute shrink and selection operator(LASSO)regression method selected the optimal subset of predictors,and multivariate logistic regression helped screen the significant factors.The nomogram model was built based on all significant factors.Area under the curve(AUC),calibration curve and decision curve analysis(DCA)were used to assess the model’s performance.Results:LASSO regression analysis selected an optimal subset containing nine predictors that were all statistically significant in multivariate logistic regression analysis.Independent risk factors of SWI included female[odds ratio(OR)=3.405,95%confidence interval(CI)=2.535-4.573],chronic obstructive pulmonary disease(OR=4.679,95%CI=2.916-7.508),drinking(OR=2.025,95%CI=1.437-2.855),smoking(OR=7.059,95%CI=5.034-9.898),re-operation(OR=3.235,95%CI=1.087-9.623),heart failure(OR=1.555,95%CI=1.200-2.016)and repeated endotracheal intubation(OR=1.975,95%CI=1.405-2.774).Protective factors included bone wax(OR=0.674,95%CI=0.538-0.843)and chest physiotherapy(OR=0.446,95%CI=0.248-0.802).The AUC of the nomogram was 0.770(95%CI=0.745-0.795)with relatively good sensitivity(0.798)and accuracy(0.620),exhibiting moderately good discernment.The model also showed an excellent fitting degree on the calibration curve.Finally,the DCA presented a remarkable net benefit.Conclusions:A visual and convenient nomogram-based risk calculator built on disease-associated predictors might help clinicians with the early identification of high-risk patients of SWI and timely intervention.
