They are the result of slow bleeding over several years. The main etiology is related to the complications of the ventriculo-peritoneal shunt (VP). The purpose of this study was to recall the peculiarities and physiopathology of its pseudotumoral hematomas through 2 observations. Observation: Case 1: 8-year-old patient with a history of ventriculoperitoneal shunt at 3 months of age for congenital hydrocephalus, was admitted for functional impotence of the left-side of the body of insidious onset spreading over 9 months in a chronic headache, blurred vision and generalized seizure. CT scan showed a heterogeneous subdural hematoma of the right frontoparietal with calcifications. The patient underwent an excision by morcellation of a yellowish, friable partly calcific mass. The postoperative history was marked by a total recovery of the neurological deficit. There was no recurrence at 6 months postoperatively. Case 2: 11-year-old adolescent, treated with VP shunt at 6 months of age for post-meningitic hydrocephalus, was admitted for helmet headache, dizziness, lightheadedness and apathy progressing for 3 years. CT scan showed hypodensity of right peri-hemisphere with calcified linings, exerting a mass effect on the medial structures. The patient was given a block excision of a calcific mass with blood content. The evolution was marked by the complete resolution of seizures and hemiparesis. There was no recurrence at 6 months postoperatively. Conclusion: Calcified subdural hematomas are rare and consecutive to the complications of VPS. The clinical signs are those of a benign brain tumor. Treatment is dominated by the difficulties of cerebral reexpression.展开更多

Between April 2006 and March 2010, a total of 18 patients undergoing unilateral burr hole drainage for B-CSDH took part in a controlled clinical study. Postoperative status of the nonsurgical side was subsequently evaluated, with (n = 10) and without (n = 8) saireito administration. Two in the saireito-treated group patients and four in the control group patients ultimately required contralateral surgical intervention. The remainder, including eight saireito-treated hematomas, resolved without further surgery, generally within eight weeks of the surgical side procedure. However, two of the four resolving control lesions took longer to regress. The hydragogue and anti-inflammatory/steroid-evoking properties ascribed to saireito may facilitate hematoma resolution. After unilateral surgery for B-CSDH, saireito administration may prevent symptomatic deterioration of a contralateral low-density CSDH, preempting subsequent surgery.展开更多

Since 5fluoro- 2'- deoxyuridine (FdU) can cause vascular injury in the murine limb and skull prior to the appearance of skeletal malformations in these structures, we studied the effects of this chemical on skeletal development in the chick embryo and noted any vascular injury. The yolk sacs of day three ehick embryos (Hamburger and Hamilton states 17-19) were injected with solutions of vary concentrations of FdU in saline. The embryos developed until the 10th day of incubation when they were fixed for study. Uninjected, saline injected, and sham injected control embryo were similarly fixed. Upon gross inspection, frequent diffuse and saccular hernatomas, as well as fluid-filled blisters, were noted in the limbs of embryos treated with FdU. After the embryos were fixed and cleared, and the skeletons stained, significant skeletal malformations were observed in these limbs. Bony elements of both the upper and lower limbs were affected in at least some of the embryos. The combination of FdU-induced hematomas and blisters with associated skeletal malformations in the same regions of some embryos suggests a relationship between these phenomena.展开更多

This brain’s condition has not well been studied in developing countries. The aim of our study is to overview the management of intracaranial hematomas in Abidjan. It is a retrospective analytical and descriptive study, involving patients who had been admitted and monitored by neurosurgeons for intracranial hematomas, documented in brain CT scan and had been operated on from 1 January 2007 to December 31, 2009 in Abidjan. These 30 patients were 23 men and 7 women. The average age was 58.6 years old. 90% of the patients were admitted with wakefulness issues. Half had a Glasgow score of less than 8. The brain scanner allowed identification of an intraparenchymal hematoma associated or not with a cerebral ventricle contamination in 28 patients. There were 18 external ventricle derivations with or without decompressive craniectomy and 12 independent decompressive craniectomy. The evolution was marked by 20 deaths. 10 patients (33.3%) survived. Among the survivors, the first attack and arterial hypertension were the only illness before the attack. None had blood in the membranes and all had Glasgow scores greater than or equal to 9 at admission. Around 7 out of 10 patients were operated on during the first 48 hours. The operative indications of intracranial hematomas are still the subject of controversy. By basing itself on criteria and rigorous clinical and neuroimaging selection, surgery could eventually contribute to the management of this pathology which has become very frequent in Africa.展开更多

Twenty-eight pa- tients were graded into Hunt-Hess grades IV-V and emergency standard micro-neurosurgeries （aneu- rysm clipping, hematoma evacuation and prophylactic hinged craniectomy） were performed, and their clinical data were retrospectively analyzed. 46.43% of the patients reached encouraged favorable out- comes on discharge. The favorable outcome group and the poor outcome group significantly differed in terms of patients＇ anisocoria, Hunt-Hess grade before surgery, extent of the midline shift and time to the surgery after bleeding （P〈0.05）. There were no significant differences in age, sex, volume and location of the hematoma, size of aneurysm between the favorable and poor groups （P〉0.05）. However, ingen- ious designed prophylactic hinged craniectomy efficiently reduced the patients＇ intracranial pressure （ICP） after surgery. It was suggested that preoperative conditions such as Hunt-Hess grading, extent of the midline shift and the occurrence of cerebral hernia affect the prognosis of patients, but time to the surgery after bleeding and prophylactic hinged craniectomy are of significant importance for optimizing the prognosis ofMCAA oatients 19resenting with large SylH.展开更多

The series enrolled forty-six consecutive cases of acute traumatic epidural hematomas. The mean age of patients was 29.56 years and 63.04% of the patients were between 21 and 30 years of age. Forty-tree out of 46 (93.47%) of the patients were males. Road traffic crash was the main mode of injury. The severity of the traumatic brain injury was classified according to the Glasgow coma scale score at admission. The injury was mild or moderate in 35 (76.08%) cases and severe in 11. Eight patients (17.39%) presented with pupillary abnormalities. The computed tomography scanning of the head has objectivized the epidural hematoma in all patients and has shown a mass effect with midline shift in all but one case (45/46). The most frequent surgical procedure done was craniotomy. Six (13.04%) patients died (GOS 1), but 38 (82.60%) recovered fully (GOS 5) and two (04.34%) were disabled but independent (GOS 4). The Glasgow coma score at admission was very predictive for good or poor outcome, since all patients but one who died and all survivors who were disabled were comatose at admission (GCS ≤ 8).展开更多

Treatment protocol depends upon the radiological finding. The loculation and multilayering indicates the bleeding at multiple times and respectively found in 13.2% and 13.6%, which was more common in patients more than 75 years. Burr hole evacuation was the treatment of choice except in recurrent cases where craniotomy was performed.展开更多

Dural opening is often associated with brain herniation against the dural edges due to associated edema that would lead to venous infarction. Aim: The objective of this study is to describe a technical note that would allow fast and effective closure of the dura after hematoma evacuation via duraplasty with analysis of the safety and competency of the technique. Subjects and Methods: The fast-track technique was implemented in 15 successive cases with acute subdural hematoma where the fascia lata flap was prepared and sutured to the planned dural incision before opening the dura, which allowed fast and effective closure of the dura before brain herniation. Subdural bridges were planned by using Gelfoam to prevent venous compression. Analysis of the technique effectiveness was performed by the operative detection of brain herniation, as well as clinical and radiological follow-up of patients. Results: All patients had a Glasgow coma score (GCS) below six before the operation. Mean time from trauma to surgery was five hours. The dura could be effectively closed with no brain herniation in all cases. Nine patients survived (60%), where five of them ended up in a vegetative state. Of these two recovered and three continued in a persistent vegetative state. The mortality rate was 40%. Post-operative infarction was detected in post-operative imaging of four patients. Conclusion: The fast-track duraplasty technique is fast and effective in prevention of brain herniation during surgery with favorable clinical outcome in comparison with the poor and severely deteriorated preoperative clinical presentation. More studies to evaluate the impact of the technique on the survival rate are warranted.展开更多

We attempt to make the surgical procedure less invasive by treating selected pediatric patients with trephination minicraniectomy. Methods： We retrospectively reviewed the clinical courses, radiological findings, surgical procedures, and prognoses of the pediatric patients who were treated in our departments for traumatic PFEDH from January 2010 to January 2015. Results： During this period, a total of 17 patients were surgically treated for PFEDH and 7 were managed with trephination mini-craniectomy for hematoma evacuation. The outcomes were good in all 7 patients as evaluated with Glasgow Outcome Score. There was no mortality in this series. The on average 30-month clinical follow-up showed that patients experienced satisfactory recoveries without complications. Conclusion： Our results suggest that trephination mini-craniectomy is a safe surgical technique for selected PFEDH patients with moderate hematoma volume and stabilized neurological functions. However, standard craniectomy is recommend when there are rapid deteriorations in patients＇ neurological functions or the hematomas are large and exerted severe mass effects.展开更多

The purpose of this study is to assess the multiple etiologies of SEH seen in an academic medical center over a 15-year span. We have examined the etiologies of SEH occurring in a single institution, the University of Pittsburgh Medical Center （UPMC） over the last fifteen years using an electronic record keeping system and database： the Medical Archive Retrieval System （MARS）. Methods We screened MARS from 1986-2001 using key words： epidural, hematoma and spinal. All potential SEH cases were reviewed and only those confirmed by surgical intervention were identified as positive SEH and reported in this study. Results There were 17 cases of confirmed SEH. Among them, seven cases were from spontaneous bleeding, seven cases following spinal surgery, and three cases from traumatic spinal fracture. There were no findings of SEH that were related to spinal or epidural anesthesia. Among the seven patients with spontaneous SEH; two were receiving anti-coagulants for deep venous thrombosis （DVT） and had elevated prothrombin time （PT） and activated partial thromboplastine time （APTT）, one had hemophilia （type B）, four had hypertension, and three out of seven had chronic renal or liver disease. Among postoperative SEH patients, two of the seven patients were receiving chemotherapy and radiation therapy and one had ongoing hemodialysis for renal failure. Among three patients with traumatic SEH, two had ankylosing spondylitis. Six patients had a history of alcohol abuse. Conclusions Spontaneous bleeding is by far the leading cause of SEH with spinal surgery being the second leading cause. Patients with multiple co-morbidities that result in coagulopathy from a variety of causes include liver or renal disease, alcohol abuse, radiation therapy, or chemotherapy. Neuraxial anesthesia is an extremely rare cause of SEH.展开更多

文摘Introduction: Calcified forms with pseudo-tumor symptomatology of chronic subdural hematomas are rare. They are the result of slow bleeding over several years. The main etiology is related to the complications of the ventriculo-peritoneal shunt (VP). The purpose of this study was to recall the peculiarities and physiopathology of its pseudotumoral hematomas through 2 observations. Observation: Case 1: 8-year-old patient with a history of ventriculoperitoneal shunt at 3 months of age for congenital hydrocephalus, was admitted for functional impotence of the left-side of the body of insidious onset spreading over 9 months in a chronic headache, blurred vision and generalized seizure. CT scan showed a heterogeneous subdural hematoma of the right frontoparietal with calcifications. The patient underwent an excision by morcellation of a yellowish, friable partly calcific mass. The postoperative history was marked by a total recovery of the neurological deficit. There was no recurrence at 6 months postoperatively. Case 2: 11-year-old adolescent, treated with VP shunt at 6 months of age for post-meningitic hydrocephalus, was admitted for helmet headache, dizziness, lightheadedness and apathy progressing for 3 years. CT scan showed hypodensity of right peri-hemisphere with calcified linings, exerting a mass effect on the medial structures. The patient was given a block excision of a calcific mass with blood content. The evolution was marked by the complete resolution of seizures and hemiparesis. There was no recurrence at 6 months postoperatively. Conclusion: Calcified subdural hematomas are rare and consecutive to the complications of VPS. The clinical signs are those of a benign brain tumor. Treatment is dominated by the difficulties of cerebral reexpression.
文摘BACKGROUND Epidural hematoma is one of the common postoperative complications after craniotomy.However,multiple remote epidural hematomas in different sites,including supratentorial and infratentorial regions,are exceedingly rare.CASE SUMMARY We present a rare case in which three remote epidural hematomas occurred after craniotomy.A 21-year-old woman was admitted with a headache for 1 mo,vomiting,and rapid vision loss for 1 wk.Brian magnetic resonance imaging indicated a right thalamic tumor.The intraoperative diagnosis was a cystic tumor,posterior cerebral artery aneurysm,and vascular malformation.The operation was successful.Unfortunately,the patient developed three extradural hematomas within 48 h.Family members consented to the first two hematoma evacuations but refused the third.CONCLUSION More attention should be paid to this kind of rare complication.Adequate preoperative evaluation is important,especially for acute patients.Monitoring neural function and early computed tomography scanning of the brain after surgery should be highlighted.
文摘The aim of this retrospective study was to investigate the efficacy of saireito for bilateral chronic subdural hematomas (B-CSDH). Between April 2006 and March 2010, a total of 18 patients undergoing unilateral burr hole drainage for B-CSDH took part in a controlled clinical study. Postoperative status of the nonsurgical side was subsequently evaluated, with (n = 10) and without (n = 8) saireito administration. Two in the saireito-treated group patients and four in the control group patients ultimately required contralateral surgical intervention. The remainder, including eight saireito-treated hematomas, resolved without further surgery, generally within eight weeks of the surgical side procedure. However, two of the four resolving control lesions took longer to regress. The hydragogue and anti-inflammatory/steroid-evoking properties ascribed to saireito may facilitate hematoma resolution. After unilateral surgery for B-CSDH, saireito administration may prevent symptomatic deterioration of a contralateral low-density CSDH, preempting subsequent surgery.

文摘The clinical characteristics of patients who presented in poor clinical grade due to ruptured middle cerebral artery aneurysms （MCAAs） associated with large sylvian hematomas （SylH） were ana- lyzed and an ingenious designed prophylactic hinged craniectomy was introduced. Twenty-eight pa- tients were graded into Hunt-Hess grades IV-V and emergency standard micro-neurosurgeries （aneu- rysm clipping, hematoma evacuation and prophylactic hinged craniectomy） were performed, and their clinical data were retrospectively analyzed. 46.43% of the patients reached encouraged favorable out- comes on discharge. The favorable outcome group and the poor outcome group significantly differed in terms of patients＇ anisocoria, Hunt-Hess grade before surgery, extent of the midline shift and time to the surgery after bleeding （P〈0.05）. There were no significant differences in age, sex, volume and location of the hematoma, size of aneurysm between the favorable and poor groups （P〉0.05）. However, ingen- ious designed prophylactic hinged craniectomy efficiently reduced the patients＇ intracranial pressure （ICP） after surgery. It was suggested that preoperative conditions such as Hunt-Hess grading, extent of the midline shift and the occurrence of cerebral hernia affect the prognosis of patients, but time to the surgery after bleeding and prophylactic hinged craniectomy are of significant importance for optimizing the prognosis ofMCAA oatients 19resenting with large SylH.
文摘This study was a retrospective analysis of outcome of surgically treated acute traumatic epidural hematomas based on the Glasgow coma scale. The series enrolled forty-six consecutive cases of acute traumatic epidural hematomas. The mean age of patients was 29.56 years and 63.04% of the patients were between 21 and 30 years of age. Forty-tree out of 46 (93.47%) of the patients were males. Road traffic crash was the main mode of injury. The severity of the traumatic brain injury was classified according to the Glasgow coma scale score at admission. The injury was mild or moderate in 35 (76.08%) cases and severe in 11. Eight patients (17.39%) presented with pupillary abnormalities. The computed tomography scanning of the head has objectivized the epidural hematoma in all patients and has shown a mass effect with midline shift in all but one case (45/46). The most frequent surgical procedure done was craniotomy. Six (13.04%) patients died (GOS 1), but 38 (82.60%) recovered fully (GOS 5) and two (04.34%) were disabled but independent (GOS 4). The Glasgow coma score at admission was very predictive for good or poor outcome, since all patients but one who died and all survivors who were disabled were comatose at admission (GCS ≤ 8).
文摘The chronic subdural hematoma is a well known entity in old age and the treatment is very challenging. Treatment protocol depends upon the radiological finding. The loculation and multilayering indicates the bleeding at multiple times and respectively found in 13.2% and 13.6%, which was more common in patients more than 75 years. Burr hole evacuation was the treatment of choice except in recurrent cases where craniotomy was performed.
文摘Background: Traumatic subdural hematoma is one of the severe injuries to brain with high mortality rates. Dural opening is often associated with brain herniation against the dural edges due to associated edema that would lead to venous infarction. Aim: The objective of this study is to describe a technical note that would allow fast and effective closure of the dura after hematoma evacuation via duraplasty with analysis of the safety and competency of the technique. Subjects and Methods: The fast-track technique was implemented in 15 successive cases with acute subdural hematoma where the fascia lata flap was prepared and sutured to the planned dural incision before opening the dura, which allowed fast and effective closure of the dura before brain herniation. Subdural bridges were planned by using Gelfoam to prevent venous compression. Analysis of the technique effectiveness was performed by the operative detection of brain herniation, as well as clinical and radiological follow-up of patients. Results: All patients had a Glasgow coma score (GCS) below six before the operation. Mean time from trauma to surgery was five hours. The dura could be effectively closed with no brain herniation in all cases. Nine patients survived (60%), where five of them ended up in a vegetative state. Of these two recovered and three continued in a persistent vegetative state. The mortality rate was 40%. Post-operative infarction was detected in post-operative imaging of four patients. Conclusion: The fast-track duraplasty technique is fast and effective in prevention of brain herniation during surgery with favorable clinical outcome in comparison with the poor and severely deteriorated preoperative clinical presentation. More studies to evaluate the impact of the technique on the survival rate are warranted.
文摘Background and Objective The natural history of type B aortic intramural hematoma(IMH)is highly heterogeneous.A computational fluid dynamics(CFD)model can be utilized to calculate a range of data pertinent to flow dynamics,including flow rates,blood velocity,pressure,and wall shear stress.This study presents a series of CFD simulations that model the dynamic progression from type B aortic IMH to false lumen formation.Methods A 66-year-old male patient presenting with chest and back pain underwent aortic computed tomography angiography(CTA),and a 3D patient-specific model was constructed.To evaluate the hemodynamic environment,the velocity,pressure,time-averaged wall shear stress(TAWSS),and oscillatory shear index(OSI)were calculated.Results A modest quantity of slow flow and recirculation flow was observed in the vicinity of the ulcer-like protrusion(ULP).During the formation of the false lumen,low-velocity blood flow entered the false lumen and resulted in vortex flow.ULPs were located in the region with higher TAWSS,and some high OSIs were found on the ULPs.Conclusion This preliminary study suggests a potential association between the TAWSS or OSI and progression from type B aortic IMH to aortic dissection.
文摘BACKGROUND Middle meningeal artery embolization(MMAE)is emerging as a promising treatment for chronic subdural hematoma(CSDH),serving both as an adjunct to surgery and as a primary therapeutic option depending on patient presentation.Due to its low recurrence rate and minimal complications,MMAE has gained increasing acceptance among clinicians in recent years.This report presents a case of diplopia following MMAE due to the presence of a potential anastomotic artery,aiming to enhance awareness of this complication.CASE SUMMARY A 60-year-old male patient presented with a headache following head trauma,and cranial computed tomography revealed a left-sided CSDH.The patient underwent left MMAE;however,polyvinyl alcohol particles inadvertently flowed into the lacrimal artery through an anastomotic artery,resulting in diplopia due to impaired abduction of the left eye.The diplopia resolved by postoperative day 40.The patient’s headache resolved by postoperative day 7,and the hematoma completely resolved by postoperative day 108.CONCLUSION Potential anastomotic arteries in the middle meningeal artery(MMA)can lead to serious complications.Superselective angiography of the MMA or its branches prior to embolization is essential.Performing embolization distal to potential anastomotic sites can reduce risks,and the presence of an anastomosis may warrant coil embolization or termination of the procedure.
文摘Chronic subdural hematoma is essentially managed by surgical intervention.In recent times,middle meningeal artery embolisation has emerged as a less invasive procedure in such cases.The use of fine catheters to selectively embolise the specific involved branches of the middle meningeal artery using polyvinyl alcohol particles looks promising;however,the presence of anastomotic arteries can result in reflux and embolisation of these atypical branches,causing a myriad of complications.There is a need to identify these abnormal vessels in time to have a positive outcome with the least complications.
文摘Subcutaneous administration of low-molecularweight heparin(LMWH)has been widely accepted as an effective anticoagulation therapy and is frequently used for patients to prevent thromboembolic events.While the usually seen bruising around the injection site during subcutaneous LMWH treatment,the abdominal wall(AW)hematoma(AWH)was scarcely observed and reported.A previous study demonstrated the usual etiological risk of AWH involved anticoagulation therapy,chronic kidney disease,and trauma.^([1])Most of these cases had a favorable prognosis after conservative treatment.
文摘BACKGROUND Hematoma expansion(HE)typically portends a poor prognosis in spontaneous intracerebral hemorrhage(ICH).Several radiographic and laboratory values have been proposed as predictive markers of HE.AIM To perform a systematic review and meta-analysis on the association of neu-trophil-to-lymphocyte ratio(NLR)and HE in ICH.A secondary outcome exa-mined was the association of NLR and perihematomal(PHE)growth.METHODS Three databases were searched(PubMed,EMBASE,and Cochrane)for studies evaluating the effect of NLR on HE and PHE growth.The inverse variance me-thod was applied to estimate an overall effect for each specific outcome by combining weighted averages of the individual studies’estimates of the logarithm odds ratio(OR).Given heterogeneity of the studies,a random effect was applied.Risk of bias was analyzed using the Newcastle-Ottawa Scale.The study was conducted following the Preferred Reporting Items for Systematic Review and Meta-analysis guidelines.The protocol was registered in PROSPERO(No.CRD42024549924).RESULTS Eleven retrospective cohort studies involving 2953 patients were included in the meta-analysis.Among those,HE was investigated in eight studies,whereas PHE growth was evaluated in three.Blood sample was obtained on admission in ten studies,and at 24 hours in one study.There was no consensus on cut-off value among the studies.NLR was found to be significantly associated with higher odds of HE(OR=1.09,95%CI:1.04-1.15,I2=86%,P<0.01),and PHE growth(OR=1.28,95%CI:1.19-1.38,I2=0%,P<0.01).Qualitative analysis of each outcome revealed overall moderate risk of bias mainly due to lack of control for systemic confounders.CONCLUSION The available literature suggests that a possible association may exist between NLR on admission and HE,and PHE growth.Future studies controlled for systemic confounders should be designed to consolidate this finding.If confirmed,NLR could be added as a readily available and inexpensive biomarker to identify a subgroup of patients at higher risk of developing HE.
文摘Middle meningeal artery embolization(MMAE)has revolutionized chronic subdural hematoma management,yet procedural risks persist due to anatomical variability.We analyze a case report by Zhao et al describing transient diplopia caused by inadvertent embolization of the lacrimal artery via a dynamic middle meningeal–ophthalmic anastomosis.This correspondence advances three critical innovations in MMAE safety.First,intraoperative anastomotic unmasking—exposing occult middle meningeal-ophthalmic collaterals during particle injection—reveals dynamic vascular behavior missed by preoperative angiography,underscoring the need for adaptive imaging protocols.Second,hybrid embolization(liquid agents for proximal occlusion+particles for distal control)balances precision and safety,reducing reflux risks compared to monotherapy.Third,a 108-day follow-up establishes a benchmark for functional recovery,challenging assumptions about irreversible cranial nerve injuries and emphasizing structured postprocedural care.Collectively,these findings advocate for procedural agility,multimodal embolic strategies,and sustained rehabilitation to optimize MMAE outcomes while minimizing iatrogenic harm.

文摘Purpose： Posterior fossa epidural hematomas （PFEDH） are uncommon in children but usually require timely surgical intervention due to the risk of life-threatening brainstem compression. We attempt to make the surgical procedure less invasive by treating selected pediatric patients with trephination minicraniectomy. Methods： We retrospectively reviewed the clinical courses, radiological findings, surgical procedures, and prognoses of the pediatric patients who were treated in our departments for traumatic PFEDH from January 2010 to January 2015. Results： During this period, a total of 17 patients were surgically treated for PFEDH and 7 were managed with trephination mini-craniectomy for hematoma evacuation. The outcomes were good in all 7 patients as evaluated with Glasgow Outcome Score. There was no mortality in this series. The on average 30-month clinical follow-up showed that patients experienced satisfactory recoveries without complications. Conclusion： Our results suggest that trephination mini-craniectomy is a safe surgical technique for selected PFEDH patients with moderate hematoma volume and stabilized neurological functions. However, standard craniectomy is recommend when there are rapid deteriorations in patients＇ neurological functions or the hematomas are large and exerted severe mass effects.
文摘Background Spinal epidural hematoma （SEH） is a rare but acute and possibly devastating clinical event. The purpose of this study is to assess the multiple etiologies of SEH seen in an academic medical center over a 15-year span. We have examined the etiologies of SEH occurring in a single institution, the University of Pittsburgh Medical Center （UPMC） over the last fifteen years using an electronic record keeping system and database： the Medical Archive Retrieval System （MARS）. Methods We screened MARS from 1986-2001 using key words： epidural, hematoma and spinal. All potential SEH cases were reviewed and only those confirmed by surgical intervention were identified as positive SEH and reported in this study. Results There were 17 cases of confirmed SEH. Among them, seven cases were from spontaneous bleeding, seven cases following spinal surgery, and three cases from traumatic spinal fracture. There were no findings of SEH that were related to spinal or epidural anesthesia. Among the seven patients with spontaneous SEH; two were receiving anti-coagulants for deep venous thrombosis （DVT） and had elevated prothrombin time （PT） and activated partial thromboplastine time （APTT）, one had hemophilia （type B）, four had hypertension, and three out of seven had chronic renal or liver disease. Among postoperative SEH patients, two of the seven patients were receiving chemotherapy and radiation therapy and one had ongoing hemodialysis for renal failure. Among three patients with traumatic SEH, two had ankylosing spondylitis. Six patients had a history of alcohol abuse. Conclusions Spontaneous bleeding is by far the leading cause of SEH with spinal surgery being the second leading cause. Patients with multiple co-morbidities that result in coagulopathy from a variety of causes include liver or renal disease, alcohol abuse, radiation therapy, or chemotherapy. Neuraxial anesthesia is an extremely rare cause of SEH.
