Effectiveness of Endoscopic Third Ventriculostomy in Obstructive Hydrocephalus of Different Etiology in Terms of Reduction of Ventricle Diameter.
J Saidu Med Col Jan ;11(4):185-90.

Background: Endoscopic techniques are now gaining insight into the management of various neurosurgical pathologies, including Endoscopic third ventriculostomy (ETV), which is a well-accepted technique for obstructive hydrocephalus of various etiologies. Objective: To determine the effectiveness of endoscopic third ventriculostomy in obstructive hydrocephalus in terms of reduction of third ventricle diameter (width).Material and Method: This descriptive case series study was conducted at the Department of Neuro Surgery, Lady Reading Hospital, from January 2019 to December 2020. A total of 195 patients between age 1- 60 years meeting the inclusion criteria underwent endoscopic third ventriculostomy by a single expert neurosurgeon. Effectiveness of endoscopic third ventriculostomy was measured to reduce at least 1 mm or more from the baseline third ventricle diameter (width) after two months of surgery. Results: In our study, 127 (65.12%) patients were male, while 68 (34.87%) were Females. Mean, and S.D. for Age was as 30.05Years + 17.46.The Mean Baseline 3rd Ventricle Diameter was 5.218mm +1.1, whereas on 60th postoperative Day Follow Up, the mean 3rd Ventricle Diameter was recorded as 4 .35mm +1.25. The difference in means between the two groups was 0.864 (p value < 0.0001), which is statistically significant. Effectiveness of Endoscopic Third Ventriculostomy was recorded on 105 (53.84%)patients, whereas in 90 (46.15%) patients, Obstructive Hydrocephalus remained unchanged. Conclusion: Calculated volumetric measurements (e.g., width) from C.T. scans after successful third ventriculostomy can display a demonstrable reduction in ventricular volume and help evaluate patients postoperatively. Keywords: ETV, Hydrocephalus, stereotactic.
