# Intraventricular Shunt as a Treatment for Entrapped Temporal Horn After Removal of Ventricular Meningioma: A Report of Two Cases

## TL;DR

This paper reports two cases where an intraventricular shunt effectively treated a rare complication after brain tumor surgery.

## Contribution

The paper introduces an intraventricular shunt using a T-connector for treating entrapped temporal horn.

## Key findings

- Intraventricular shunt with a T-connector is effective for entrapped temporal horn.
- Temporal-frontal horn and trigone-front horn shunts were successfully used in two patients.
- The shunt provided good prognosis and resolved the space-occupying effect.

## Abstract

Entrapped temporal horn (ETH) is a complication following resection of ventricular trigone tumors. It is a special localized hydrocephalus. Obstruction of cerebrospinal fluid outflow following resection of ventricular trigone tumors leads to dilation of the temporal horn and the production of the local space-occupying effect. This article presents two cases of ETH following the resection of ventricular trigone tumors. Our Intraventricular shunt is an effective treatment that uses a T-connector to connect a reservoir with two catheters. We presented temporal-frontal horn shunt and trigone-front horn shunt. A patient presented with ETH shunt dependency. Our intraventricular shunt surgery achieved a good prognosis.
