Summary
Endoscopic ventriculocisternostomy with stent placement (EVSP) effectively treats trapped temporal horn (TTH) hydrocephalus. This neuroendoscopic procedure offers a safe alternative to traditional shunts, showing significant ventricle size reduction and symptom improvement.
Area of Science:
- Neurosurgery
- Hydrocephalus Management
- Minimally Invasive Procedures
Background:
- Trapped temporal horn (TTH) is a specific type of obstructive hydrocephalus.
- Traditional ventriculoperitoneal shunts carry risks of failure and infection.
- Neuroendoscopy offers ventriculocisternostomy as a less invasive alternative.
Purpose of the Study:
- To evaluate the safety and efficacy of endoscopic ventriculocisternostomy with stent placement (EVSP) for treating TTH.
- To compare EVSP with traditional shunt procedures for TTH.
Main Methods:
- Retrospective data collection of TTH patients treated with EVSP (September 2013 - September 2021).
- Creation of a ventricular stoma using neuroendoscopy with placement of a stent tube to ensure patency.
- Evaluation of patient characteristics, procedural outcomes, and ventricle size changes.
Main Results:
- 10 TTH patients (mean age 56.7 years) were included with follow-up averaging 35 months.
- Underlying causes included postoperative scarring and intraventricular/extraventricular tumors.
- No procedural complications occurred; one patient had recurrence. All patients showed symptom resolution and significant (84.5%) trapped ventricle shrinkage.
Conclusions:
- Endoscopic ventriculocisternostomy with stent placement (EVSP) is a safe and feasible treatment for TTH.
- EVSP presents a viable and effective alternative to ventriculoperitoneal shunts for TTH.
- The procedure leads to substantial clinical and radiological improvement in TTH patients.
