Endoscopic third ventriculostomy in obstructive hydrocephalus: surgical technique and pitfalls

Area of Science:

• Neurosurgery
• Minimally Invasive Procedures
• Pediatric Neurosurgery

Background:

• Obstructive hydrocephalus presents diverse pathological origins.
• Endoscopic treatment offers a minimally invasive approach.
• Evaluating surgical technique, nuances, and potential pitfalls is crucial.

Purpose of the Study:

• To assess the effectiveness of endoscopic third ventriculostomy (ETV) for obstructive hydrocephalus.
• To analyze surgical nuances and identify potential pitfalls in ETV procedures.
• To determine the safety and efficacy of ETV as a primary treatment.

Main Methods:

• Retrospective review of 57 consecutive patients with obstructive hydrocephalus treated with ETV over 9 years.
• Inclusion of septostomy in ten cases.
• Reassessment of operative videos and surgical nuances.

Main Results:

• ETV was successful in 54 out of 57 patients (94.7%).
• An overall success rate of 81.5% (44/54) was achieved, with patients remaining shunt-independent.
• Benign aqueductal stenosis and tumors compressing the aqueduct showed the greatest benefit; no permanent morbidities or mortality were reported.

Conclusions:

• Endoscopic third ventriculostomy (ETV) is a safe and effective first-line treatment for obstructive hydrocephalus.
• Thorough understanding of ventricular anatomy and variations is essential for successful ETV.
• Meticulous preoperative planning and awareness of potential pitfalls are mandatory to minimize risks.
