Objective: The aim of this study is to determine the frequency of complication among patients after endoscopic third ventriculostomy in obstructive hydrocephalus.

Study Design: Descriptive study

Place and Duration: Conducted at the department of Neurosurgery, Bacha Khan Medical College Mardan/ Medical Complex Mardan and Frontier Medical and Dental College, Abbottabad for duration of 06 months from April 2021 to September 2021.

Methods: There were one hundred and fifteen patients of both genders with ages 1-40 years were presented. Included patients had obstructive hydrocephalus. Detailed demographics, including age, sex, and BMI, were obtained from all patients with signed permission. Patients underwent CT scan and brain MRI. Endoscopic third ventriculostomy was performed among all the cases after indication of symptoms. Post-treatment effectiveness and complication were assessed after follow up within duration of 2-weeks. SPSS 25.0 version was used to analyze all data.

Results: Mean age of the patients was 6.2 ±3.25 years. Among 115 cases, 70 (60.9%) were males and 45 (29.1%) were female patients. Aqueductal stenosis was the most common disease found in 77 (67%) cases followed by posterior fossa tumours 20 (17.4%), VP shunt blocked in 17 (14.8%) and CSF ascites in 3 (2.6%) cases. We found complications in 24 (20.9%) cases CSF leak was the most common found in 12 (10.4%) cases, meningitis in 4 (3.5%), seizures  and bleeding in 3 (2.6%). Mortality found in 2 (1.7%) cases.

Conclusion: We concluded in this study that the endoscopic third ventriculostomy is an effective and safe method for the patients of obstructive hydrocephalus in terms of minimum complication with lower rate of mortality.
