Background: Endoscopic third ventriculostomy (ETV) has been shown to be a sufficient alternative to shunts in surgical treatment of obstructive hydrocephalus. Long-term failure, age limitations, and outcome by cause are some of the issues debated in literature. The objective of this article is to analyze the clinical success and failure of ETV and its main complications. Methods: A total of 209 patients with hydrocephalus were submitted to ETV, including a mixed population of children and adults (from 0 to 59 years). Patients were divided into five groups: A – tumors, B – aqueductal stenosis, C – myelomeningocele, D – infection and hemorrhage, and E – arachnoid cyst. Variables were analyzed: age, ETV success rate, cerebrospinal fluid (CSF) fistula, mortality, and complications. Results: The two main causes of hydrocephalus were tumors (44.9%) and aqueductal stenosis (25.3%). The overall success rate was of 82.8%, and patients in Group E had the highest rate 90.9%. Group A had a success rate of 89.3%, and Group B had a rate of 88.6%. The ETV success rate was significantly higher in patients older than 1 year (P < 0.001); the former also had a lower risk of CSF fistula (P < 0.0001). The overall mortality rate was 2.8%. Conclusion: Better results were observed in the groups of patients with tumors, aqueductal stenosis, and arachnoid cysts, while those whose primary causes of hydrocephalus were myelomeningocele, infections, or bleeding had higher rates of failure after the procedure. This study demonstrated that age under 1 year and hydrocephalus caused by myelomeningocele, bleeding, and infection were considered independent risk factors of poor prognosis in ETV.

Background Endoscopic third ventriculostomy (ETV) is one of the important management options for hydrocephalus, especially obstructive hydrocephalus. The result of ETV in different age and etiology is quite variable according to the different authors. The study was carried out to assess the success rate of ETV as a treatment for this type of hydrocephalus in infant age group. Material and Methods The study was done prospectively on infants (age ≤ 12 months) admitted in the period from January 2009 to June 2013 suffering from obstructive hydrocephalus due to cerebral aqueductal stenosis (CAS). After making the diagnosis, we counseled the patient party about the probability of high failure rate of ETV in this age group and probable necessity of a second operation. With the informed consent, we performed ETV in these cases and followed up regularly in postoperative period. Control neuroimaging studies were done whenever needed (suspected failure of ETV and suspected stomal block). Results Total 17 infants were studied. Average follow-up was 18.7 months. Twelve infants were between the age group of six and under six months while five were above six months to one year old. Fourteen (82.35%) out of 17 patients showed overall clinical improvement. Clinical improvement was seen in two (66.6%) infants aged 2 months or younger, three (75%) aged 2+ to 3 months, five (100%) aged 3+ to 6 months, and four (80%) aged 6+ months to 1 year. Two patients had bleeding during surgery. Three developed CSF leak through the burr hole. In one case (the patient's age was 2 months), the stoma was found blocked, and hydrocephalus returned 9 weeks after ETV. In two patients, in whom VP shunt was needed, “failed ETV” was obvious in early postoperative period. In this series, average ETV success score (ETVSS) was 52.35 (range: 40–70) and overall success rate was 82.35%. This indicates that ETVSS does not correlate with the outcome of ETV in infants with CAS. Conclusion Outcome of ETV for hydrocephalus from CAS in infant is quite good and ETVSS does not correlate with the outcome.

OBJECT Endoscopic third ventriculostomy (ETV) is the procedure of choice in the treatment of obstructive hydrocephalus. The excellent clinical and radiological success rates are well known. Nevertheless, very few papers have addressed the very long term outcomes of the procedure in very large series. The authors present a large case series of 113 patients who underwent 126 ETVs, and they highlight the initial postoperative outcome after 3 months and long-term follow-up with an average of 7 years. METHODS All patients who underwent ETV at the Department of Neurosurgery, Mainz University Hospital, between 1993 and 1999 were evaluated. Obstructive hydrocephalus was the causative pathology in all cases. RESULTS The initial clinical success rate was 82% and decreased slightly to 78% during long-term follow-up. Long-term success was analyzed using Kaplan-Meier curves. Overall, ETV failed in 31 patients. These patients underwent a second ETV or shunt treatment. A positive impact on long-term success was seen for age older than 6 months, and for obstruction due to cysts or benign aqueductal stenosis. The complication rate was 9% with 5 intraoperative and 5 postoperative events. CONCLUSIONS The high clinical success rate in short-term and long-term follow-up confirms ETV’s status as the gold standard for the treatment of obstructive hydrocephalus, especially for distinct pathologies. The patient’s age and underlying pathology may influence the outcome. These factors should be considered carefully preoperatively by the surgeon.

<b><i>Background:</i></b> 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. <b><i>Aims and Objectives:</i></b> 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. <b><i>Material and Methods:</i></b> 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. <b><i>Results:</i></b> 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. <b><i>Conclusion:</i></b> ETV is a good surgical procedure for less than 1-year-old children.

Endoscopic third ventriculostomy (ETV) is a routine and safe procedure for therapy of obstructive hydrocephalus. The aim of our study is to evaluate ETV success rate in therapy of obstructive hydrocephalus in pediatric patients formerly treated by ventriculoperitoneal (V-P) shunt implantation. From 2001 till 2011, ETV was performed in 42 patients with former V-P drainage implantation. In all patients, the obstruction in aqueduct or outflow parts of the fourth ventricle was proved by MRI. During the surgery, V-P shunt was clipped and ETV was performed. In case of favourable clinical state and MRI functional stoma, the V-P shunt has been removed 3 months after ETV. These patients with V-P shunt possible removing were evaluated as successful. In our group of 42 patients we were successful in 29 patients (69%). There were two serious complications (4.7%)—one patient died 2.5 years and one patient died 1 year after surgery in consequence of delayed ETV failure. ETV is the method of choice in obstructive hydrocephalus even in patients with former V-P shunt implantation. In case of acute or scheduled V-P shunt surgical revision, MRI is feasible, and if ventricular system obstruction is diagnosed, the hydrocephalus may be solved endoscopically.

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.

Endoscopic third ventriculostomy is the procedure of choice to treat obstructive hydrocephalus now a days. Published case series of endoscopic third ventriculostomy (ETV) for childhood hydrocephalus have reported widely varying success rates. The purpose of this study is to determine the success rate and complications of ETV for treating obstructive hydrocephalus.Patients with obstructive hydrocephalus and already shunted patients for obstructive hydrocephalus presented with blocked shunt were included in the study. The exclusion criteria consisted ofrecurrent tumor or intra ventricular hemorrhage. Endoscopic third ventriculostomy was performed. Patients were followed up for one year and Clinical and Radiological improvement, complications and mortality was noted. This study was conducted in Neurosurgery Department, Govt. Medical College, Kota between 2015-2016.There were 56 patients including 36 males and 20females. Success rate in the form of clinical and/ or radiological improvement was seen in 88.8% 0f patients. Complications were seen in 6 patients including ETV failure and ventricular hemorrhage. There was no mortality during follow up period of 1 year.ETV is cost effective and safe procedure in patients with obstructive hydrocephalus with good outcome. It may be used as replacement procedure of ventriculo-peritoneal shunt as initial line of management in selected patients based on ETV score. Nepal Journal of Neuroscience, Vol. 14, No. 2,  2017 Page: 21-24

OBJECT Endoscopic third ventriculostomy (ETV) is the treatment of choice for obstructive hydrocephalus; however, the success of ETV in patients who have previously undergone shunt placement remains unclear. The present study analyzed 103 adult patients with aqueductal stenosis who underwent ETV for obstructive hydrocephalus and evaluated the effect of previous shunt placement on post-ETV outcomes. METHODS This study was a retrospective review of 151 consecutive patients who were treated between 2007 and 2013 with ETV for hydrocephalus. One hundred three (68.2%) patients with aqueductal stenosis causing obstructive hydrocephalus were included in the analysis. Postoperative ETV patency and aqueductal and cisternal flow were assessed by high-resolution, gradient-echo MRI. Post-ETV Mini-Mental State Examination, Timed Up and Go, and Tinetti scores were compared with preoperative values. Univariate and multivariate analyses were performed comparing the post-ETV outcomes in patients who underwent a primary (no previous shunt) ETV (n = 64) versus secondary (previous shunt) ETV (n = 39). RESULTS The majority of patients showed significant improvement in symptoms after ETV; however, no significant differences were seen in any of the quantitative tests performed during follow-up. Symptom recurrence occurred in 29 (28.2%) patients after ETV, after a median of 3.0 (interquartile range 0.8–8.0) months post-ETV failure. Twenty-seven (26.2%) patients required surgical revision after their initial ETV. Patients who received a secondary ETV had higher rates of symptom recurrence (p = 0.003) and surgical revision (p = 0.003), particularly in regard to additional shunt placement/revision post-ETV (p = 0.005). These differences remained significant after multivariate analysis for both symptom recurrence (p = 0.030) and surgical revision (p = 0.043). CONCLUSIONS Patients with obstructive hydrocephalus due to aqueductal stenosis exhibit symptomatic improvement after ETV, with a relatively low failure rate. Patients with a primary history of shunt placement who undergo ETV as a secondary intervention are at increased risk of symptom recurrence and need for surgical revision post-ETV.

Object Endoscopic third ventriculostomy (ETV) has become a well-accepted option for obstructive hydrocephalus. However, standard ventriculostomy at the floor of the third ventricle might not be feasible under certain conditions. Here, the authors report in detail on their initial experience with an alternative option of endoscopic ventriculostomy through the lamina terminalis via a transventricular route. Methods Endoscopic third ventriculostomy through the lamina terminalis from a transventricular transforaminal route was evaluated in 4 cadaveric human heads and in 4 clinical cases. Results In all 4 human cadavers, an opening of the lamina terminalis via a transventricular approach could be achieved without injury to either the optic chiasm or the anterior cerebral arteries. In the 4 clinical cases, an accurate and reliable ventriculostomy was performed at the lamina terminalis. The bur hole was placed directly at the coronal suture 2 cm lateral from the midline. After identifying the optic chiasm and the anterior cerebral arteries, a blunt perforation was made just anterior to the optic chiasm by using perforation forceps and a balloon catheter. After the opening, the stoma was inspected with a 0° and 30° rod lens endoscope, and its patency as well as the preservation of vessels and optic nerves was checked. No complications occurred, although all patients suffered from a clinically silent fornical contusion at the foramen of Monro. Conclusions Endoscopic opening of the lamina terminalis via a transventricular transforaminal route appears to be feasible. No complications were observed. Although no conclusions on the clinical success rate can be drawn, the reliable anatomical opening and known success rate for anterior subfrontal approaches suggest that the technique represents an alternative in a small subgroup of patients in whom a standard ETV cannot be performed.

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.
