Endoscopic Management of Intraventricular Neurocysticercosis.

Abstract

To evaluate the technique and outcome of endoscopic management of intraventricular neurocysticercosis (NCC). We retrospectively analysed the records of 30 consecutive patients of intraventricular (intra-third and fourth ventricle) NCC who underwent endoscopic management. The clinical profiles of the patients were evaluated which included age, symptoms and signs. Transcranial endoscopy was performed through a frontal burr hole using a Gaab Universal Endoscope system with rigid 0° and 30° telescope for endoscopic third ventriculostomy and removal of the cyst was described. The mean follow-up period was 22.6 months. In 86.67% (26/30) patients we are able to visualize/excise/decompress the cyst. We were able to successfully excise all the third ventricular cysts (16/16) and in 66.67% (8/12) of the fourth ventricular cysts. In 90% (27/30) patients we were able to successfully divert the CSF flow and achieve long-term shunt free period. We found that endoscopic cerebrospinal fluid (CSF) diversion in cases of intraventricular NCC is feasible and associated with high success rate. Endoscopic CSF diversion in NCC related hydrocephalus usually produces a long-term cure.
