Endoscopic septostomy through a standard precoronal ventricular access: feasibility and effectiveness.

Area of Science:

• Neurosurgery
• Pediatric Neurosurgery
• Neurology

Background:

• Endoscopic septostomy is a common treatment for hydrocephalus, but indications and techniques are debated.
• Ventricular access for endoscopic septostomy is a particular area of discussion.
• This study evaluates endoscopic septostomy using a standard precoronal ventricular access with a rigid endoscope.

Purpose of the Study:

• To evaluate the safety and efficacy of endoscopic septostomy performed via a standard precoronal ventricular access.
• To assess the clinical and radiological outcomes of this procedure in a cohort of patients with hydrocephalus.

Main Methods:

• Retrospective review of 63 patients (50 children, 13 adults) who underwent endoscopic septostomy between March 2001 and March 2011.
• Analysis of clinico-radiological data and video recordings of the procedures.
• Standard precoronal ventricular access using a rigid endoscope.

Main Results:

• Septostomy was successful in 61 out of 63 patients; failure was due to a scarred septum in two cases.
• Common causes of hydrocephalus included neoplasms (adults and children), post-hemorrhagic/infectious (children), and malformative (children).
• Overall, 95% of patients showed clinical and radiological improvement, with a 92% long-term success rate. Late obstruction occurred in two patients with tumors.

Conclusions:

• Endoscopic septostomy through a standard burr-hole is a safe and effective neurosurgical procedure.
• The approach demonstrates high early (over 95%) and long-term (92%) success rates for treating hydrocephalus.
• This technique provides a reliable option for cerebrospinal fluid (CSF) pathway obstruction.
