Introduction:
An intraventricular cysticercus cyst is observed in 7%-30% patients of neurocysticercosis (NCC). Apart from causing arachnoiditis, intraventricular NCC (IVNCC) can cause sudden death due to acute episodes of hydrocephalus. Various treatment modalities available are external cerebrospinal fluid (CSF) diversion, microsurgical removal, and endoscopic management. There is no consensus regarding the optimal surgical treatment strategy. We are presenting our experience by doing a retrospective analysis of 26 patients having endoscopic removal of IVNCC with a rigid endoscope and angiocatheter.
Aim:
The aim of this study is to evaluate the results of neuroendoscopy in restoring the CSF pathway and removal of the cyst in patients of IVNCC.
Materials And Methods:
Retrospective analysis of clinical record and follow-up of 26 patients of IVNCC who were treated endoscopically between 2010 and 2018 was done. The diagnosis of IVNCC was made based on contrast enhanced magnetic resonance imaging of the brain. Transcranial endoscopy with 0° endoscope was performed through the frontal burr hole. Third ventriculostomy and removal of the cysticercus cyst with angiocatheter were the procedures done.
Results:
The success rate of intraventricular cyst excision, whether complete or partial, was 100% (14/14) in the third ventricular cyst, 62.5% (5/8) in the fourth ventricular cyst and 100% (4/4) in the lateral ventricular cyst. The overall success rate of cyst excision by endoscopy was 88.46%. The overall successful CSF flow pathway was established in 88.46% cases. The mean duration of follow-up was 44 months, and all the patients were found symptom free in the follow-up period.
Conclusion:
Neuroendoscopy, being a single burr hole technique successfully providing internal CSF diversion and cyst removal, is the treatment modality of choice for IVNCC.
