Endoscopic Third Ventriculostomy in Children with Failed Ventriculoperitoneal Shunt

Area of Science:

• Neurosurgery
• Pediatric Neurosurgery
• Hydrocephalus Management

Background:

• Endoscopic third ventriculostomy (ETV) is established for obstructive hydrocephalus.
• Its efficacy in managing shunt malfunction requires further evaluation.
• This study assesses ETV in pediatric patients previously treated with ventriculoperitoneal (V-P) shunts.

Purpose of the Study:

• To evaluate the success rate of ETV in pediatric patients experiencing shunt malfunction.
• To determine ETV's viability as an alternative to shunt revision after initial V-P shunt failure.

Main Methods:

• Retrospective analysis of 33 pediatric patients with obstructive hydrocephalus and first-time shunt failure.
• Patients underwent ETV between 2008 and 2014.
• Data collected on hydrocephalus causes, ETV outcomes, and follow-up duration.

Main Results:

• Common causes included aqueductal stenosis and myelomeningocele.
• ETV succeeded in 20 out of 33 cases (60.6%); 13 required shunt revision.
• No serious complications were noted during ETV procedures; mean follow-up was 18 months.

Conclusions:

• ETV is a viable alternative treatment for obstructive hydrocephalus in patients with prior shunt failure.
• The procedure demonstrates an acceptable success rate of approximately 60%.
• Long-term follow-up is essential to fully ascertain the durability of ETV outcomes in this cohort.
