Objective:
To evaluate and discuss the outcomes of a combination of ventriculocystostomy (VC) and endoscopic third ventriculostomy (ETV) for obstructive hydrocephalus (HCP) due to ventricular/cisternal arachnoid cysts, and only ETV for obstructive HCP due to different etiologies.
Methods:
We retrospectively reviewed all 40 symptomatic patients (aged 4 months - 61 years) of obstructive HCP treated by ETV or VC+ETV during October 2014 - April 2019. VC+ETV was performed in 7 patients with intraventricular/cisternal arachnoid cyst and obstructive HCP. Only ETV was performed in 33 patients with obstructive HCP due to other etiologies.
Results:
Successful ETV or VC+ETV surgery was performed in 35 patients. The procedure failed in 5 patients aged 90 percentile at the time of surgery. Another 5 patients aged 90 percentile).
