ENDOSCOPIC THIRD VENTRICULOSTOMY (ETV);

Objective: To know the surgical outcome of endoscopic third ventriculostomy(ETV) in non communicating hydrocephalous. Materials and methods: This study wasconducted in Abaseen Hospital, Peshawar, from 13th December 2010 to 12th October 2011.Patients with non-communicating hydrocephalous, irrespective of gender discrimination wereincluded in this study. Patients with communicated hydrocephalous, patients below two years ofage and hydrocephalus with infected CSF or hemorrhage were excluded. Hydrocephalous wasdiagnosed on CT scan brain. The procedure was done under general anesthesia. ClinicalOutcome of ETV was evaluated by the time of discharge and on subsequent follow up visits i.e.monthly for the first three months and then at six months. Any patient who subsequently neededVP shunting after the ETV procedure was described as having treatment failure. Results: Weoperated 27 patients during our study period. Age ranged from 2 years to 57 years with mean age20.8 years. There were 16(59.26%) males and 11(40.74 %) females. Etiologically,4th ventriculartumors was present in 9 patients(33.33%), tuberculous meningitis in 8(29.62%), aquiductalstenosis in 7(25.92%), brain stem glioma in 1(3.70%). cerebellar haemengioblastoma in 1(3.70%)and pineal tumor (3.70%) with infra tentorial extension in 1 (3.70%) patient. The procedure wassuccessful in 24(88.89%) patients and converted to ventriculoperitoneal shunts in 3(11.11%)cases. Post operatively CSF leakage was present in 2 (7.40%) patients, transient memory loss in1(3.70%), pneumocephalus in 1(3.70%) and pseudomeningocele in 1(3.70%) patients.Conclusions: Endoscopic third ventriculostomy is a good alternative to the VP shunt in cases ofnon-communicating hydrocephalous. Although ETV does have some complications but theseare transient and can be minimized with proper patient selection and meticulous surgicaltechnique

Abstract Purpose Intraventricular neuroendoscopic techniques, particularly third ventriculostomy, are employed increasingly in the management of infantile hydrocephalus. However, surgical access to the ventricular cavities is associated with a risk of post-operative cerebrospinal fluid (CSF) leak. Here, we describe a structured, multi-layered approach to wound opening and closure which aims to maximise the natural tissue barriers against CSF leakage. We present a series of patients undergoing this technique and subsequently review the literature regarding opening and closure techniques in paediatric intraventricular neuroendoscopic procedures. Methods We performed a retrospective case series analysis of patients under 1 year of age who underwent intraventricular neuroendoscopic procedures in a single institution over a 5-year period. Patients were identified from an institutional operative database, and operation notes and clinical records were subsequently reviewed. Results 28 patients fulfilled the inclusion criteria for this study. The mean age at operation was 9 weeks. 27 patients underwent endoscopic third ventriculostomy whilst 1 underwent endoscopic septostomy, and all patients underwent our structured, multi-layered opening and closure technique. Follow-up ranged from 4 months to 5 years. There were no cases of post-operative CSF leak, infection or wound breakdown. 12 patients remained shunt-free at the last follow-up, with the remaining 16 requiring shunt insertion for progressive hydrocephalus at a mean of 24 days post-operatively. Conclusion Various methods aiming to prevent post-operative CSF leak have been reported in the literature. We propose that our institutional technique may be of benefit in minimising this risk in infants undergoing endoscopic third ventriculostomy and similar intraventricular neuroendoscopic procedures.

Case Presentation

Introduction: Hydrocephalus is not usually part of Down syndrome (DS). Fourth ventricle outlet obstruction is a rare cause of obstructive hydrocephalus, difficult to diagnose, because tetraventricular dilatation may suggest a communicant/nonobstructive hydrocephalus. Case Presentation: We describe the case of a 6-year-old boy with obstructive tetraventricular hydrocephalus, caused by Luschka and Magendie foramina obstruction and diverticular enlargement of Luschka foramina (the so-called fourth ventricle outlet obstruction) associated with DS. He was treated with endoscopic third ventriculostomy (ETV) without complications, and a follow-up MRI revealed reduction of the ventricles, disappearance of the diverticula, and patency of the ventriculostomy. Conclusion: Diverticular enlargement of Luschka foramina is an important radiological finding for obstructive tetraventricular hydrocephalus. ETV is a viable option in tetraventricular obstructive hydrocephalus in DS.

Background: Endoscopic third ventriculostomy (ETV) is currently considered as an alternative to cerebrospinal fluid (CSF) shunt systems in the treatment of obstructive hydrocephalus. This procedure allows the CSF to drain in the basal cisterns and reabsorbed by arachnoid granulations, and avoiding implantation of exogenous material. Aims and Objectives: The purpose of this study was to assess the success rate of ETV in infants less than 1 year of age with congenital noncommunicating hydrocephalus. Material and Methods: This study was a 2-year prospective study from August 2017 to July 2019. ETVs were performed in 14 patients younger than 1 year with diagnosis of noncommunicating hydrocephalous. A failure was defined as the need for shunt implantation after ETV. Phase-contrast MRI of the brain was done after 6 months to see patency of ETV fenestration and CSF flow through ventriculostomy. Results: ETV was tried in 18 patients and successfully performed in 14 patients. Out of the 14 patients, shunt implantation after ETV was performed in 3 patients (failed ETV). In the successful cases, etiology was idiopathic aqueductal stenosis in 8, shunt complications in 2, and 1 case was a follow-up case of occipital encephalocele; the mean age was 7.7 months (range 3–12). In the 3 failed cases, etiology was aqueductal stenosis, mean age was 7.6 months (range 3–11). In all ETVs, failed patients MPVP shunting was done. Follow-up of nonshunted patients was done from 6 to 24 months (mean 15 months). There was no mortality or permanent morbidity noted following ETV. Conclusion: ETV is a good surgical procedure for less than 1-year-old children.

CONTEXT: VP Shunt is most commonly used procedure for hydrocephalus but shunt failure is also the common complication in many patients. Endoscopic third ventriculostomy (ETV) is an accepted procedure for the treatment of obstructive hydrocephalus. The aim of our study is to evaluate the success rate AIM AND OBJECTIVE - of ETV in patients of obstructive hydrocephalus formerly treated by ventriculo-peritoneal (VP shunt) shunt. The failure VP shunt was removed before ETV. MATERIALS AND METHOD: This study was conducted between June 2015 and December 2019 in single unit of our department. Twenty one (n=21) patients were enrolled for this study. All patients were admitted with failure of VP shunt. They were known case of non-communicating hydrocephalus previously operated for VP shunt. Six patients were excluded for ETV because CT/MRI show grossly distorted anatomy of ventricles. Endoscopic third ventriculostomy was attempted in 15 patients, but ventriculostomy was done successfully in 10 patients, rests were treated with revision of VP shunt. All patients in this study were radiologically diagnosed RESULTS: case of hydrocephalus due to aqueduct stenosis. They were experienced VP shunt insertion but there were failure of shunt due to any reason. ETV procedures were done successfully in 10 patients. Out of 10 patients one patient needed shunt insertion due ineffective ETV. Shunt revision was done in 11 patients. There was no serious complication during and after ETV procedures. The follow-up period of patients with successful ETV was 6–60 months. This follow-up was uneventful and peaceful for their parents. ETV can be considered as an alternative treatment for the patients w CONCLUSION: ith VP shunt failure with an acceptable success rate of 80%, although long-term follow-up is needed for these patients.

Dandy–Walker syndrome associated with syringomyelia is a rare condition, with few reports of adult cases. We describe an adult case of Dandy–Walker syndrome with concomitant syringomyelia. A 33-year-old man presented with a 3-month history of walking instability, numbness in the hands, memory deterioration, and urinary incontinence. A physical examination showed a positive Romberg sign. Brain computed tomography and magnetic resonance imaging showed hydrocephalus, a cyst in the posterior fossa, absence of the cerebellar vermis, hypoplasia of the corpus callosum and cerebella, and syringomyelia. All of these symptoms were consistent with the diagnosis of Dandy–Walker syndrome. Surgery involving arachnoid adhesiolysis and endoscopic third ventriculostomy was performed. At the 6-month follow-up, the symptoms were completely relieved. Magnetic resonance imaging showed that syringomyelia was greatly reduced and the hydrocephalus remained unchanged. Dandy–Walker syndrome with concomitant syringomyelia in adults is exceedingly rare. Early diagnosis and appropriate surgical treatment of this condition should be highlighted. Combined arachnoid adhesiolysis and endoscopic third ventriculostomy may be an effective approach.

ABSTRACT BACKGROUND: Routinely, hydrocephalus related to fourth ventricular outlet obstruction (FVOO) has been managed with ventriculoperitoneal (VP) shunting or endoscopic third ventriculostomy (ETV). Few reports on Magendie foraminoplasty exist, and Luschka foraminoplasty has not been described. OBJECTIVE: To present an alternative technique in the management of FVOO via an endoscopic transventricular transaqueductal Magendie and Luschka foraminoplasty and to discuss the indications, technique, findings, and outcomes. METHODS: Between 1994 and 2011, all patients who underwent endoscopic Magendie and Luschka foraminoplasty were analyzed. RESULTS: A total of 33 Magendie (28) and/or Luschka (5) foraminoplasties were performed in 30 patients. Twenty-three were adult and 7 were pediatric patients. The etiology of the FVOO was divided into primary etiologies (congenital membrane in 5 and atresia in 2) and secondary causes (neurocysticercosis in 14 patients, bacterial meningitis in 9). Fifteen (50%) had previously failed procedures. Intraoperative findings that led to Magendie/Luschka foraminoplasty were ETV not feasible to perform, nonpatent basal subarachnoid space, or primary FVOO. Minor postoperative complications were seen in 3 patients. Only 26 patients had long-term follow-up; 17 (65.3%) of these had clinical improvement and did not require further procedures. Nine (34.7%) did not improve. Eight required another procedure (7 shunts, and 1 endoscopic procedure). One patient died. CONCLUSION: Flexible neuroendoscopic transventricular transforaminal Magendie and Luschka foraminoplasty is feasible and safe. These procedures may prove to be viable alternatives to standard ETV and VP shunt in appropriate patients. Adequate intraoperative assessment of ETV success is necessary to identify patients who will benefit.

Abstract INTRODUCTION Myelomeningocele is associated with hydrocephalus in 35% to 90% of cases. Hydrocephalus is usually treated with insertion of ventriculoperitoneal shunt. However, endoscopic third ventriculostomy with or without choroid plexus cauterization is a viable alternative. METHODS A prospective longitudinal study from January 2016 to December 2018 on patients with myelomeningocele who presented to Lagos University Teaching Hospital, Nigeria and who had hydrocephalus.Informed consent for research and surgery were obtained. ETV with or without CPC or VPS was done with general anesthesia using standard operative techniques. Patients were followed up monthly for at least 6 mo. The surgery was adjudged failed if there was progressive head enlargement as well as other signs of hydrocephalus necessitating another surgery for hydrocephalus. RESULTS A total of 48 patients completed the study. A total of Six patients were lost to follow-up. Age range of the patients was 1 to 44 wk. A total of Five patients had ETV, 21 had ETV/CPC, and 22 patients had VPS. The mean OFC at the time of surgery were 45.3 cm and 44.9 cm for the endoscopic and VPS arms respectively. There were 2 (7.6%) cases of CSF leak in the endoscopic arm and 3 (13.6%) cases of wound dehiscence, with 1 (4.5%) case of CSF leak in the VPS arm. Mean age at surgery for ETV/CPC arm was 12.3 wand 11.5 wk for the VPS arm. Mean time to failure was 9.9 and 6.3 wk for endoscopic and VPS arms respectively. Four (80%) of the patients who had ETV had a successful outcome, 11 (52.3%) of those who had ETV/CPC had a successful outcome and 13 (59%) of those who had VPS had a successful outcome. At 6 mo follow up, overall success rate for the endoscopic arm was 57.6% and 59% for the VPS. CONCLUSION Endoscopic third ventriculostomy with or without choroid plexus cauterization had similar success rate with VPS at 6 mos.

Choroid Plexus Cauterization

Object Shunt dependence is more dangerous for children in less developed countries. Combining endoscopic third ventriculostomy (ETV) with choroid plexus cauterization (CPC) was previously shown to treat hydrocephalus more effectively than ETV alone in infants < 1 year of age. The goal of this prospective study was to evaluate the effectiveness of ETV-CPC as primary treatment of hydrocephalus in infants with myelomeningocele. Methods One hundred fifteen consecutive East African infants with myelomeningocele requiring treatment for hydrocephalus were intended for primary management using ETV-CPC. Patient information was prospectively entered into a database. Outcomes were evaluated by life table analysis. Potential predictors for treatment failure were evaluated using multivariate logistic regression. Results Ninety-three patients had a completed ETV-CPC with > 1 month of follow-up. The ETV-CPC procedure was successful in 71 patients (76%), with a mean and median follow-up of 19.0 months. Treatment failures occurred before 6 months in 86% of the patients, and none occurred after 10 months. The operative mortality rate was 1.1%, and there were no infections. Life table analysis suggested that 72% of the patients would be successfully treated using a single ETV-CPC and 78% would remain shunt-independent with reopening of a closed ETV stoma. Multivariate logistic regression showed scarring of the cistern (p = 0.021) or choroid plexus (p = 0.026) as predictors of failure, but age at the time of surgery was not a significant predictor. Conclusions Using ETV-CPC appears to successfully provide a more durable primary treatment of hydrocephalus for infants with spina bifida than does shunt placement. These results support ETV-CPC as the better treatment option for these children in developing countries.

Neurocytomas are typically intraventricular in location, and extraventricular neurocytomas are uncommon. The authors report the unique case of a 15-year-old girl who was found to have a low-grade neurocytoma infiltrating the brainstem and cerebellum and spreading along the CSF pathways to the lateral and third ventricles. The patient underwent endoscopic third ventriculostomy to treat associated hydrocephalus, and biopsy specimens from intraventricular tumor nodules were obtained. Because of the low-grade pathology, the fact that the lesion was not amenable to resection, and the extensive radiation field required for radiation therapy, she has been treated conservatively with close follow-up. Over the course of almost 4 years since diagnosis, no additional treatment has been required. Neurocytoma with widespread infiltration of the brainstem and cerebellum has not been previously reported.
