Post-PEG complications were compared between two groups according to the presence or absence of VP shunts. VP shunt infection rates, the interval between PEG placement and VP shunt catheter insertion, and long-term follow-up were also investigated.RESULTS: Fifty-five patients qualified for the study. Seven patients (12.7%) had pre-existing VP shunts. All patients received prophylactic antibiotics. The complication rate did not differ between VP shunt patients undergoing PEG (PEG/VP group) and non-VP shunt patients undergoing PEG (control group) [1 (14.3%) vs 6 (12.5%), P=1.000]. All patients in the PEG/VP group had undergone VP shunt insertion prior to PEG placement. The mean interval between VP shunt insertion and PEG placement was 308.7 d (range, 65-831 d). The mean follow-up duration in the PEG/VP group was 6.4 mo (range, 1-15 mo). There were no VP shunt infections, although one patient in the PEG/VP group developed a minor peristomal infection during follow-up.CONCLUSION: Complications following PEG placement in patients with VP shunts were infrequent in this study.展开更多

Several theories have been suggested to explain its occurrence. The main symptoms are painful abdominal distension and vomiting, abdominal distension on examination, as abdominal ultrasound and computed tomography confirm its diagnosis. The treatment involves drainage associated with drain relocation and resection of the pseudocyst’s wall. We report two patients diagnosed with this condition who underwent surgical treatment. The first patient had an unremarkable 12-month follow-up, while the second died on the seventh postoperative day due to intravascular disseminated coagulation. In these patients, the cause has not been identified;however, an infection cannot be ruled out.展开更多

Since 1908, ventriculoperitoneal shunts have been considered the best option in hydrocephalus management. Manifestation related to VPS may arise anywhere whilst tunneling the VPS from the ventricle to the peritoneal cavity, but complications associated with the distal catheter are especially common and a leading cause of revision surgeries. Among the many complications associated with peritoneal shunts, migration of the catheter into other parts of the body is still common. Scrotal migration mainly takes place in children aged 4 days to 5 years. Patent processus vaginalis, formation of an inguinal hernia, and increased intraabdominal pressure are leading risk factors associated with migration of the peritoneal catheter into the scrotum. Thoracic migration of peritoneal catheters predominantly occurs in adult patients. Important mechanisms in thoracic migration include(1) iatrogenic perforation of the external or internal jugular veins by the surgeon during tunneling and(2) gradual destruction of the venous structures by the catheter due to routine extension and flexion of the neck. After entering the vessel, negative intrathoracic pressure combined with positive intraabdominal pressure aids migration into the thoracic cavity. Sharp tips or shunt types contribute to intraabdominal migration and perforation.展开更多

Methods: The study was conducted in the Department of Pediatric Neurosurgery, National Neuroscience Institute, King Fahad Medical City, Riyadh, Saudi Arabia from January 2010 to December 2013. The data were collected retrospectively. The patients who had emergency insertion of external ventricular drain (EVD) due to hydrocephalus before the definitive posterior fossa tumor surgery were included in the study. Results: The preoperative emergency insertion of EVD was done in 38 patients with pediatric posterior fossa tumors. The patients were divided into two groups. Group A consists of those patients who had duration of preoperative EVD equal or less than 7 days. Group B includes those patients who had duration of preoperative EVD more than 7 days. Group A has 16 patients while Group B has 22 patients. The predominant clinical feature was symptoms and signs of raised intracranial pressure (ICP) only. Infection related to EVD was seen in seven patients. Ventriculoperitoneal (VP) shunt was required in 31.25% of Group A patients and 18.18% of Group B patients (p value = 0.35). Overall shunt rate was 23.68%. Conclusion: There are well known number of factors that can determine the need of permanent CSF diversion in patients with posterior fossa tumors. However, there is no effect of preoperative duration of EVD in determining the requirement of postoperative VP shunt.展开更多

CSF diversion procedures are commonly used for treatment if medical treatment failed. The aim of this study is to report our experience in treatment of IIH with lumboperitoneal (LP) and stereotactic guided ventriculoperitoneal (VP) shunts. The clinical data of 43 consecutive patients with IIH refractory to medical treatment and underwent CSF diversion procedures between 2009 and 2014 were analyzed. 29 patients underwent LP shunts and the remaining 14 patients underwent stereotactic guided Ventricular shunts. All patients underwent clinical, imaging and CSF manometry evaluation. 38 (88.4%) patients were female and the remaining 5 (11.6%) patients were male. The mean age was 27.2 years. The opening pressure was above 300 mm H2O in 26 (69.8%) patients. Headache (100%) and blurring and/or diminution of vision (81.4%) were the commonest clinical presentation. 36 (83.7%) patients reported recovery of their headache and 30 (69.7%) patients showed complete resolution of papilledema. The clinical outcome between both procedures was not significant. The incidence of perioperative complications (20.7% vs. 0%) and shunt revisions (27.6% vs. 7.1%) were higher in patients with LP shunt than patients with stereotactic Ventricular shunts. The results of this study demonstrate that both LP and Ventricular shunts are valid diversion procedures for treatment of IIH. Stereotactic guided Ventricular shunt has lower incidence of complications and revisions and seems to be safe, effective and feasible alternative procedure for treatment of IIH.展开更多

Case Report: We report the case of a 36-year-old with severe scoliosis status post repair over a decade ago, neurofibromatosis type I, and a known large meningocele in the left thoracic cavity, presenting with new acute respiratory compromise. She was taken to the operating room for a lumboperitoneal shunt, but the operation was aborted due to her severe spinal deformity. Two days later, she successfully underwent a procedure for ventriculoperitoneal shunt placement. Upon discharge a week later, the patient was hemodynamically stable, able to move all extremities with good strength, and demonstrated improved oxygenation. In the following 7 months, the patient demonstrated continued minimal requirement on nasal cannula, and MRI showed a stable left thoracic giant meningocele. Conclusion: Ventriculoperitoneal shunting is a method of treating and stabilizing acutely symptomatic giant meningoceles.展开更多

However, there is no therapeutic consensus, especially the place of drainage of cerebrospinal fluid (CSF). We report the result of our experience on the management of this pathology from a group of patients with a high volume VS (Koos IV) and operated consecutively. After reflections based on current literature data, we propose a therapeutic decisional algorithm. Materials and Methods: This is an analytical, retrospective study of 171 patients operated on KOOS IV vestibular schwannoma from January 2003 to December 2016 at the Marseille University Hospital Center. Of these, 32 patients with hydrocephalus and stage IV vestibular schwannoma were included. Radio-diagnostic criteria for hydrocephalus were based on Evans’ index, cortical furrow status, and the presence of trans-ependymal resorption. Our sample was divided into 2 groups. The first consisted of patients first operated on their hydrocephalus and secondarily treated with schwannoma surgery (group I);patients who underwent surgical resection of their first-line tumor were group II. Epidemiological, clinical, radiological, therapeutic and monitoring data were analyzed. The comparison of the quantitative variables was made by Fisher’s test. Results: During our study period (13 years), 171 cases of stage IV SV had been operated. The association between hydrocephalus and SV stage IV of Koos accounted for 18.7%. The average age of our patients was 53 years with a sex ratio of 0.7. The clinical picture was primarily composed of otological signs (90.6%), headache (56.3%) and cerebellar involvement (43.8%). The average diameter of VS inponto-cerebellar angle (PCA) was 31.5 mm. The treatment consisted of placing a first shunt of the CSF in 34.4% (group I). The ventriculoperitoneal shunt (VPS) was performed in 90.9% of cases. The first surgical removal of the tumor (group II) involved 65.6% of the patients. The postoperative tumor residue averaged 0.76 cc. The Evans index was evaluated on average at 0.33 in each of the 2 groups postoperatively. The average follow-up time for patients was 51 months. Eight cases of complications were recorded during the study. Secondly, in group II, VPS was performed in 9.5% (2 cases). Conclusion: Hydrocephalus is a condition commonly associated with stage IV vestibular schwannoma. The first optimal surgical excision of the tumor seems to be the treatment of choice for this pathological association. The success of the surgery is very often related to the management of hydrocephalus pre, per and post operative.展开更多
文摘BACKGROUND Intra-gastric migration of the distal ventriculoperitoneal shunt(VPS)catheter clinically presenting with or without trans-oral extrusion is one of the rare complications of VPS catheter insertion.AIM To identify the demographics,clinical presentation,clinical findings,and results of surgical therapy offered for the treatment of intra-gastric migration of the distal VPS catheter,clinically presented with or without trans-oral extrusion.METHODS An online search was performed for the extraction/retrieval of the published/available literature pertaining to the above-mentioned VPS complication.Manuscripts were searched from PubMed,PMC(PubMed Central),ResearchGate,and Google Scholar databases using various terminology relating to the VPS complications.The first case of migration of a VPS catheter into the stomach was reported in the year 1980,and the data were retrieved from 1980 to December 2022.Cases were categorized into two groups;Group A:Cases who had migration of the distal VPS catheter into the stomach and clinically presented with trans-oral extrusion of the same,and Group B:Cases who had migration of the distal VPS catheter into the stomach,but presented without trans-oral extrusion.RESULTS A total of n=46 cases(n=27;58.69%male,and n=19;41.3%females)were recruited for the systematic review.Group A included n=32,and Group B n=14 cases.Congenital hydrocephalus was the indication for the primary VPS insertion for approximately half of the(n=22)cases.Approximately sixty percent(n=27)of them were children≤5 years of age at the time of the diagnosis of the complication mentioned above.In seventy-two percent(n=33)cases,this complication was detected within 24 mo after the VPS insertion/last shunt revision.Clinical diagnosis was evident for the entire group A cases.Various diagnostic modalities were used to confirm the diagnosis for Group B cases.Various surgical procedures were offered for the management of the complication in n=43 cases of both Groups.In two instances,intra-gastric migration of the distal VPS catheter was detected during the autopsy.This review documented four deaths.CONCLUSION Intra-gastric migration of the peritoneal end of a VPS catheter is one of the rare complications of VPS catheter implantation done for the treatment of hydrocephalus across all age groups.It was more frequently reported in children,although also reported in adults and older people.A very high degree of clinical suspicion is required for the diagnosis of a case of an intra-gastric migration of the distal VPS catheter clinically presenting without transoral extrusion.

文摘BACKGROUND Delayed intracranial hemorrhage(DICH),a potential complication of ventriculoperitoneal(VP)shunts,has been associated with high mortality,but its risk factors are still unclear.AIM To investigate the risk factors of DICH after VP shunts.METHODS We compared the demographic and clinical characteristics of DICH and non-DICH adult patients with VP shunts between January 2016 and December 2020.RESULTS The 159 adult VP shunt patients were divided into 2 groups according to the development of DICH:the DICH group(n=26)and the non-DICH group(n=133).No statistically significant difference was found in age,sex,laboratory examination characteristics or preoperative modified Rankin Scale(mRS)score between the DICH and non-DICH groups(P>0.05);however,a history of an external ventricular drain(EVD)[P=0.045;odds ratio(OR):2.814;95%CI:1.024-7.730]and postoperative brain edema around the catheter(P<0.01;OR:8.397;95%CI:3.043-23.171)were associated with a high risk of DICH.A comparison of preoperative mRS scores between the DICH group and the non-DICH group showed no significant difference(P=0.553),while a significant difference was found in the postoperative mRS scores at the 3-mo follow-up visit(P=0.024).CONCLUSION A history of EVD and postoperative brain edema around the catheter are independent risk factors for DICH in VP shunt patients.DICH patients with a high mRS score are vulnerable to poor clinical outcomes.
文摘AIM:To investigate whether percutaneous endoscopic gastrostomy (PEG) tube placement is safe in patients with ventriculoperitoneal (VP) shunts.METHODS: This was a retrospective study of all patients undergoing PEG insertion at our institution between June 1999 and June 2006. Post-PEG complications were compared between two groups according to the presence or absence of VP shunts. VP shunt infection rates, the interval between PEG placement and VP shunt catheter insertion, and long-term follow-up were also investigated.RESULTS: Fifty-five patients qualified for the study. Seven patients (12.7%) had pre-existing VP shunts. All patients received prophylactic antibiotics. The complication rate did not differ between VP shunt patients undergoing PEG (PEG/VP group) and non-VP shunt patients undergoing PEG (control group) [1 (14.3%) vs 6 (12.5%), P=1.000]. All patients in the PEG/VP group had undergone VP shunt insertion prior to PEG placement. The mean interval between VP shunt insertion and PEG placement was 308.7 d (range, 65-831 d). The mean follow-up duration in the PEG/VP group was 6.4 mo (range, 1-15 mo). There were no VP shunt infections, although one patient in the PEG/VP group developed a minor peristomal infection during follow-up.CONCLUSION: Complications following PEG placement in patients with VP shunts were infrequent in this study.
文摘We are describing a case of a female infant with ventriculoperitoneal shunt scheduled for inguinal hernia repair under spinal anesthesia. The child was a premature newborn who, in a recent past, underwent surgery in general anesthesia for retinopathy correction with subsequent difficult mechanical ventilation weaning. The benefit of spinal anesthesia in high-risk infant was described and the risks of spinal anesthesia in the presence of a ventricular shunt device-especially dural leakage and infections were briefly discussed.
文摘An abdominal cerebrospinal fluid pseudocyst is a rare complication of ventriculoperitoneal shunt. Several theories have been suggested to explain its occurrence. The main symptoms are painful abdominal distension and vomiting, abdominal distension on examination, as abdominal ultrasound and computed tomography confirm its diagnosis. The treatment involves drainage associated with drain relocation and resection of the pseudocyst’s wall. We report two patients diagnosed with this condition who underwent surgical treatment. The first patient had an unremarkable 12-month follow-up, while the second died on the seventh postoperative day due to intravascular disseminated coagulation. In these patients, the cause has not been identified;however, an infection cannot be ruled out.

文摘Traumatic acute subdural hematoma is one of the most lethal causes of head injuries,which leads to high mortality.While combined diseases always make it more intractable for the treatment.We present a case of a 68-year-old female patient with traumatic acute subdural hematoma combined with hydrocephalus after ventriculoperitoneal shunt assisted by the neuronavigation system in January 12,2017.She was undergone ventriculoperitoneal shunt 6 years and 5 months ago on two sides respectively because of hydrocephalus,with the ventriculoperitoneal shunt device on the right side out of work.The initial neurological examination showed a Glasgow Coma Scale of E2V1M5 with no papillary defect.A CT scan of the head revealed a left homogeneously hyperdense and subdural hematoma,with compression of the lateral ventricle(2.6 cm thick)and a 0.5 cm midline shift.To protect the ventriculoperitoneal shunt device,we used neuronavigation system to precisely mark the relative location of the device and“invisible”subdural hematoma,thus to design a perfect incision preoperatively.Subsequently,evacuation of the subdural hematoma was performed via craniotomy without damaging the ventriculoperitoneal shunt device.Postoperative CT of the head showed totally removing of the subdural hematoma.The patient recovered three months later.With the assistant of neuronavigation system,it is much easier for the preoperative planning and to reduce the surgical risk.Our case gives a clue that more approaches can be considered when encountering acute head trauma with the complicated combined diseases.
文摘Objective:To analyze the effect of ventriculoperitoneal shunt on the recovery of brain function in children with hydrocephalus.Methods:The clinical data of 40 children with hydrocephalus were retrospectively analyzed.Ventriculoperitoneal shunt was performed with 9003 shunt tube and P.S.Shunt tube,B.C.E.shunt tube.Electroencephalogram(EEG),and brain CT/MRI were performed before and after surgery,and postoperative follow-up was carried out to observe the therapeutic effect.Results:In this study,there were seven cases of intracranial injury,seven cases of congenital hydrocephalus,11 cases of ventricular end obstruction,three cases of abdominal end obstruction,nine cases complicated with bacterial infection,and 3 cases of shunt entering the scrotum.The prognosis of all the children was good,and there were no significant changes in eight cases.Conclusion:Ventriculoperitoneal shunt is effective in the treatment of children with hydrocephalus.

文摘A ventriculoperitoneal shunt(VPS) is a medical device used to deflect cerebrospinal fluid from cerebral ventricles to the peritoneal cavity. Since 1908, ventriculoperitoneal shunts have been considered the best option in hydrocephalus management. Manifestation related to VPS may arise anywhere whilst tunneling the VPS from the ventricle to the peritoneal cavity, but complications associated with the distal catheter are especially common and a leading cause of revision surgeries. Among the many complications associated with peritoneal shunts, migration of the catheter into other parts of the body is still common. Scrotal migration mainly takes place in children aged 4 days to 5 years. Patent processus vaginalis, formation of an inguinal hernia, and increased intraabdominal pressure are leading risk factors associated with migration of the peritoneal catheter into the scrotum. Thoracic migration of peritoneal catheters predominantly occurs in adult patients. Important mechanisms in thoracic migration include(1) iatrogenic perforation of the external or internal jugular veins by the surgeon during tunneling and(2) gradual destruction of the venous structures by the catheter due to routine extension and flexion of the neck. After entering the vessel, negative intrathoracic pressure combined with positive intraabdominal pressure aids migration into the thoracic cavity. Sharp tips or shunt types contribute to intraabdominal migration and perforation.
文摘Dear Editor,The incidence of complications associated with ventriculoperitoneal(VP)shunts ranges from 24%to 47%,with abdominal complications comprising 25%of these cases[1].The shunt may migrate to various body parts,including the abdominal wall,gastrointestinal tract,vagina,bladder,scrotum,mediastinum,and the oral cavity.Cerebrospinal fluid(CSF)leakage through the vagina is an uncommon complication of VP shunts;however,its exact incidence remains unknown.Such complications can result in failure of the shunt procedure,often requiring revision or reinsertion in affected patients[2].
文摘BACKGROUND Cerebrospinal fluid(CSF)pseudocysts are uncommon complications of ventriculoperitoneal(VP)shunts,usually occurring within 3 weeks to 10 years of insertion.We report a perihepatic CSF pseudocyst presenting over 27 years after shunt placement,representing an exceptionally long interval compared with prior reports.This case highlights the importance of maintaining diagnostic openness when investigating unexplained ascites,and demonstrates the role of fluid beta-2 transferrin in confirming a rare diagnosis.CASE SUMMARY A 42-year-old man with spina bifida and prior VP shunt insertion was admitted for urinary tract infection,later developing recurrent symptomatic perihepatic fluid collections.Extensive hepatic,cardiac,and surgical evaluations were unremarkable,and repeated percutaneous drainages failed.The possibility of CSF origin was raised after clinical reappraisal,and beta-2 transferrin testing of the drained fluid confirmed a CSF pseudocyst.The patient underwent VP shunt exploration and revision with relocation to the pleural space,leading to resolution of the abdominal collections and symptoms.CONCLUSION Persistent diagnostic uncertainty requires broad clinical suspicion and selective testing to identify rare causes of ascites.
文摘OBJECTIVE The aim of this study was to provide a comprehensive benchmark of 30-day ventriculoperitoneal(VP)shunt failure rates for a single institution over a 5-year study period for both adult and pediatric patients,to compare this with the results in previously published literature,and to establish factors associated with shunt failure.METHODS A retrospective database search was undertaken to identify all VP shunt operations performed in a single,regional neurosurgical unit during a 5-year period.Data were collected regarding patient age,sex,origin of hydrocephalus,and whether the shunt was a primary or secondary shunt.Operative notes were used to ascertain the type of valve inserted,which components of the shunt were adjusted/replaced(in revision cases),level of seniority of the most senior surgeon who participated in the operation,and number of surgeons involved in the operation.Where appropriate and where available,postoperative imaging was assessed for grade of shunt placement,using a recognized grading system.Univariate and multivariate models were used to establish factors associated with early(30-day)shunt failure.RESULTS Six hundred eighty-three VP shunt operations were performed,of which 321 were pediatric and 362 were adult.The median duration of postoperative follow-up for nonfailed shunts(excluding deaths)was 1263 days(range 525-2226 days).The pediatric 30-day shunt failure rates in the authors'institution were 8.8%for primary shunts and 23.4%for revisions.In adults,the 30-day shunt failure rates are 17.7%for primary shunts and 25.6%for revisions.In pediatric procedures,the number of surgeons involved in the operating theater was significantly associated with shunt failure rate.In adults,the origin of hydrocephalus was a statistically significant variable.Primary shunts lasted longer than revision shunts,irrespective of patient age.CONCLUSIONS A benchmark of 30-day failures is presented and is consistent with current national databases and previously published data by other groups.The number of surgeons involved in shunt operations and the origin of the patient's hydrocephalus should be described in future studies and should be controlled for in any prospective work.The choice of shunt valve was not a significant predictor of shunt failure.Most previous studies on shunts have concentrated on primary shunts,but the high rate of early shunt failure in revision cases(in both adults and children)is perhaps where future research efforts should be concentrated.
文摘BACKGROUND Dandy-Walker malformation(DWM)was first reported in 1914.In this case report,a pediatric case was complicated with giant and isolated arachnoid cysts in the right cerebellar hemisphere along with the typical DWM.CASE SUMMARY The patient was at 20 mo old boy,with the complaint of staggering for more than 2 mo.He was admitted to the hospital due to high intracranial pressure and staggering.At admission,the patient had typical manifestations of high intracranial pressure,including vomiting,poor appetite and feeding difficulty.Physical examination revealed increased head circumference,closed anterior fontanelle,unstable standing,staggering,leaning right while walking and ataxia.After admission,he was diagnosed with DWM accompanied by giant isolated arachnoid cysts in the posterior fossa.He underwent Y-shaped three-way valve repair for treating differential pressure between the supratentorial hydrocephalus and the subtentorial arachnoid cysts at once.The child recovered well after the surgery.CONCLUSION In this case,supratentorial and subtentorial shunts were placed,which solved the problem of differential pressure between the supratentorial and subtentorial parts simultaneously.This provides useful information regarding treatment exploration in this rare disease.

文摘BACKGROUND The common treatment for hydrocephalus is insertion of a ventriculoperitoneal shunt.Shunt tube displacement is one of the common complications.Most shunt tube displacements occur in children and has a reportedly lower incidence in adults.CASE SUMMARY This study reports an adult patient(male,56 years)who suffered from intracranial aneurysm and subarachnoid hemorrhage and underwent aneurysm clipping following hospitalization.One month post onset of the disease,the patient underwent ventriculoperitoneal shunt due to hydrocephalus.The peritoneal end of the shunt tube was displaced in the peritoneal cavity 9 years after the aneurysm clipping.The peritoneal end of the shunt tube was removed and ventriculoperitoneal shunt was re-performed after anti-inflammatory treatment.CONCLUSION Shunt tube displacement has a low incidence in adults.In order to avoid shunt tube displacement,there is a need to summarize its causative factors and practice personalized medicine.
文摘Objective: Aim of the study was to assess the duration of preoperative external ventricular drain (EVD) as a predictor for permanent cerebrospinal fluid (CSF) diversion in pediatric posterior fossa tumors. Methods: The study was conducted in the Department of Pediatric Neurosurgery, National Neuroscience Institute, King Fahad Medical City, Riyadh, Saudi Arabia from January 2010 to December 2013. The data were collected retrospectively. The patients who had emergency insertion of external ventricular drain (EVD) due to hydrocephalus before the definitive posterior fossa tumor surgery were included in the study. Results: The preoperative emergency insertion of EVD was done in 38 patients with pediatric posterior fossa tumors. The patients were divided into two groups. Group A consists of those patients who had duration of preoperative EVD equal or less than 7 days. Group B includes those patients who had duration of preoperative EVD more than 7 days. Group A has 16 patients while Group B has 22 patients. The predominant clinical feature was symptoms and signs of raised intracranial pressure (ICP) only. Infection related to EVD was seen in seven patients. Ventriculoperitoneal (VP) shunt was required in 31.25% of Group A patients and 18.18% of Group B patients (p value = 0.35). Overall shunt rate was 23.68%. Conclusion: There are well known number of factors that can determine the need of permanent CSF diversion in patients with posterior fossa tumors. However, there is no effect of preoperative duration of EVD in determining the requirement of postoperative VP shunt.
文摘Idiopathic intracranial hypertension (IIH) is a disorder characterized by increased intracranial pressure without any identifiable etiology with normal brain imaging and normal cerebrospinal fluid (CSF) content. CSF diversion procedures are commonly used for treatment if medical treatment failed. The aim of this study is to report our experience in treatment of IIH with lumboperitoneal (LP) and stereotactic guided ventriculoperitoneal (VP) shunts. The clinical data of 43 consecutive patients with IIH refractory to medical treatment and underwent CSF diversion procedures between 2009 and 2014 were analyzed. 29 patients underwent LP shunts and the remaining 14 patients underwent stereotactic guided Ventricular shunts. All patients underwent clinical, imaging and CSF manometry evaluation. 38 (88.4%) patients were female and the remaining 5 (11.6%) patients were male. The mean age was 27.2 years. The opening pressure was above 300 mm H2O in 26 (69.8%) patients. Headache (100%) and blurring and/or diminution of vision (81.4%) were the commonest clinical presentation. 36 (83.7%) patients reported recovery of their headache and 30 (69.7%) patients showed complete resolution of papilledema. The clinical outcome between both procedures was not significant. The incidence of perioperative complications (20.7% vs. 0%) and shunt revisions (27.6% vs. 7.1%) were higher in patients with LP shunt than patients with stereotactic Ventricular shunts. The results of this study demonstrate that both LP and Ventricular shunts are valid diversion procedures for treatment of IIH. Stereotactic guided Ventricular shunt has lower incidence of complications and revisions and seems to be safe, effective and feasible alternative procedure for treatment of IIH.
文摘Objective: The authors report a rare case of giant thoracic meningocele causing acute respiratory compromise, treated with a ventriculoperitoneal shunt. Case Report: We report the case of a 36-year-old with severe scoliosis status post repair over a decade ago, neurofibromatosis type I, and a known large meningocele in the left thoracic cavity, presenting with new acute respiratory compromise. She was taken to the operating room for a lumboperitoneal shunt, but the operation was aborted due to her severe spinal deformity. Two days later, she successfully underwent a procedure for ventriculoperitoneal shunt placement. Upon discharge a week later, the patient was hemodynamically stable, able to move all extremities with good strength, and demonstrated improved oxygenation. In the following 7 months, the patient demonstrated continued minimal requirement on nasal cannula, and MRI showed a stable left thoracic giant meningocele. Conclusion: Ventriculoperitoneal shunting is a method of treating and stabilizing acutely symptomatic giant meningoceles.
文摘Introduction: The association hydrocephalus and vestibular schwannoma (VS) has been known for a long time. However, there is no therapeutic consensus, especially the place of drainage of cerebrospinal fluid (CSF). We report the result of our experience on the management of this pathology from a group of patients with a high volume VS (Koos IV) and operated consecutively. After reflections based on current literature data, we propose a therapeutic decisional algorithm. Materials and Methods: This is an analytical, retrospective study of 171 patients operated on KOOS IV vestibular schwannoma from January 2003 to December 2016 at the Marseille University Hospital Center. Of these, 32 patients with hydrocephalus and stage IV vestibular schwannoma were included. Radio-diagnostic criteria for hydrocephalus were based on Evans’ index, cortical furrow status, and the presence of trans-ependymal resorption. Our sample was divided into 2 groups. The first consisted of patients first operated on their hydrocephalus and secondarily treated with schwannoma surgery (group I);patients who underwent surgical resection of their first-line tumor were group II. Epidemiological, clinical, radiological, therapeutic and monitoring data were analyzed. The comparison of the quantitative variables was made by Fisher’s test. Results: During our study period (13 years), 171 cases of stage IV SV had been operated. The association between hydrocephalus and SV stage IV of Koos accounted for 18.7%. The average age of our patients was 53 years with a sex ratio of 0.7. The clinical picture was primarily composed of otological signs (90.6%), headache (56.3%) and cerebellar involvement (43.8%). The average diameter of VS inponto-cerebellar angle (PCA) was 31.5 mm. The treatment consisted of placing a first shunt of the CSF in 34.4% (group I). The ventriculoperitoneal shunt (VPS) was performed in 90.9% of cases. The first surgical removal of the tumor (group II) involved 65.6% of the patients. The postoperative tumor residue averaged 0.76 cc. The Evans index was evaluated on average at 0.33 in each of the 2 groups postoperatively. The average follow-up time for patients was 51 months. Eight cases of complications were recorded during the study. Secondly, in group II, VPS was performed in 9.5% (2 cases). Conclusion: Hydrocephalus is a condition commonly associated with stage IV vestibular schwannoma. The first optimal surgical excision of the tumor seems to be the treatment of choice for this pathological association. The success of the surgery is very often related to the management of hydrocephalus pre, per and post operative.
