Frequency of success and complications of primary endoscopic third ventriculostomy in infants with obstructive hydrocephalous

Objectives: To determine the success rate and complications of primary endoscopic third ventri-culostomy (ETV) in infants with obstructive hydrocephalous. Methods: This case series was conducted at the Department of Neurosurgery, Medical and Teaching Institute, Lady Reading Hospital Peshawar from July 2016 to June 2018. All consecutive patients with age less than one year who underwent ETV for primary obstructive hydrocephalous, of both gender, were included in the study. The patients were followed up to six months after surgery. The data was entered in a specially designed Performa. Patients’ data was analyzed using SPSS version 21.0. Results: We had total 21 patients with age less than one year during the study period. Male patients were 11 (52.4%). Success rate of ETV at six months of follow up was 12 (57.1%). Post-op complications observed were in 9.52% (2/21) cases. One patient had cerebrospinal fluid CSF) leak and the other had significant bleed. Conclusion: ETV is successful in 57.1% of infants with obstructive type of hydrocephalous. The post op complications in case of ETV are lower than Ventriculo-peritoneal shunts. Therefore, ETV can be offered to infants having obstructive hydrocephalous. doi: https://doi.org/10.12669/pjms.38.1.4097 How to cite this:Sharafat S, Khan Z, Azam F, Ali M.

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.

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.

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.

Introduction. To evaluate outcomes of wide-diameter (6 mm) implants immediately provisionalized with cement-retained single crowns in posterior molar sites.Materials and Methods. Forty-eight consecutive patients received a total of 53 moderately rough-surface, 6 mm diameter implants in healed sites. All implants were immediately provisionalized with a cement-retained provisional crown. Final prosthesis with cement-retained porcelain fused to metal crowns was delivered 3–6 months later. Patients were followed up for 1 year. Outcome measures were implant failures and success rate, complications, marginal bone levels, bone level changes, papilla index, bleeding on probing, and inflammation.Results. One patient was lost to follow-up. At one year, the implant survival and success rate were 98.1%. The mean marginal bone loss after 1 year was −0.17±1.84 mm. Ideal papilla score was recorded at 83.8% of the sites. More than 95.6% of the sites showed no bleeding or inflammation. No procedure-related or device-related adverse events were reported.Conclusion. Wide-diameter (6 mm) implants can safely and successfully replace single posterior molars. Longer follow-up studies are necessary to evaluate the long-term success of these implants.

Introduction: Obstructive hydrocephalus has long been managed by valve-regulated shunts. These shunts are associated with a myriad of short and long-term complications. This has fueled interest in Endoscopic Third Ventriculostomy (ETV) which provides a more physiological pathway for cerebrospinal fluid (CSF) diversion while avoiding many shunt-related complications. Aim: The objective of this study is to analyze the outcomes of ETV at our institution, focusing on the indications, success rates, and short-term complications. Methods: Between July 2010 and September 2015, 47 patients with obstructive hydrocephalus underwent ETV at the Neurosurgery Teaching Hospital in Baghdad/ Iraq. We retrospectively analyzed the data of these patients using hospital health records. Simple statistics were performed using SPSS Version 20. A standardized surgical technique was employed in all cases. Results: The mean age was 4.4 years (range 40 days - 38 years). The male: female ratio was 1.23:1 (55% males and 45% females). The most common cause of obstructive hydrocephalus in patients undergoing ETV was aqueductal stenosis (62%; N=29). The second most common cause was posterior fossa tumours (23%; N=11). The overall success rate for ETV was 68%. The net post-operative complication rate was 13% (N=6). CSF leak and seizures were the only two charted post-operative complications at the rates of 9%(N=4) and 4% (N=2), accordingly. No deaths were recorded. Conclusion: ETV is a viable alternative to shunt insertion in a select group of patients with obstructive hydrocephalus, with acceptable success rate and safety profile.

Choroid Plexus Cauterization

OBJECT Combining endoscopic third ventriculostomy (ETV) with choroid plexus cauterization (CPC) has been shown to improve the success rate compared with ETV alone in infants (less than 24 months) with hydrocephalus who were treated in developing countries. The authors sought to evaluate the safety and efficacy of this procedure, using a rigid neuroendoscope, in a single North American center, and to assess whether the ETV success score (ETVSS), the CURE Children’s Hospital of Uganda ETVSS (CCHU ETVSS), and other pre- and intraoperative variables could predict success. METHODS The authors performed a retrospective review of consecutive ETV/CPC procedures performed using a rigid neuroendoscope to treat infantile hydrocephalus. The infants underwent the procedure at Miami Children’s Hospital between January 2007 and 2014, with at least one postoperative follow-up. Duration of follow-up or time to failure of ETV/CPC, the primary outcome measure, was documented. A repeat CSF diversion procedure or death was considered as a failure of ETV/CPC. The time to event was measured using a Kaplan-Meier analysis. The authors analyzed ETVSS, CCHU ETVSS, and pre- and intraoperative variables to determine their suitability to predict success. RESULTS Eighty-five patients (45 boys) with a mean age of 4.3 months (range 1 day to 20 months) underwent ETV/CPC. Etiology included intraventricular hemorrhage of prematurity in 44 patients (51.7%), myelomeningocele (MMC) in 7 (8.2%), congenital aqueductal stenosis in 12 (14.1%), congenital communicating hydrocephalus in 6 (7.1%), Dandy-Walker complex in 6 (7.1%), postinfectious hydrocephalus in 5 (5.8%), and other cause in 5 (5.8%). Six procedure-related complications occurred in 5 (5.8%) patients, including 2 hygromas, 1 CSF leak, and 3 infections. There were 3 mortalities in this cohort. ETV/CPC was successful in 42.1%, 37.7%, and 36.8% of patients at 6, 12, and 24 months follow-up, respectively. The median (95% CI) time to ETV/CPC failure was 4.0 months (0.9–7.1 months). In univariate analyses, both the ETVSS (hazard ratio [HR] 1.03; 95% CI 1.01–1.05; p = 0.004) and CCHU ETVSS (HR 1.48; 95% CI 1.04–2.09; p = .028) were predictive of outcome following ETV/CPC. In multivariate analysis, the presence of prepontine scarring was associated with ETV/CPC failure (HR 0.34; 95% CI 0.19–0.63; p < 0.001). Other variables, such as radiological criteria (prepontine interval, prepontine space, aqueductal stenosis, Third Ventricular Morphology Index) and intraoperative findings (ventriculostomy pulsations, extent of CPC), did not predict outcome. CONCLUSIONS ETV/CPC is a feasible alternative to ETV and ventriculoperitoneal shunt in infants with hydrocephalus. Both the ETVSS and CCHU ETVSS predicted success following ETV/CPC in this single-center North American cohort of patients.
