Endoscopic third ventriculostomy in obstructed hydrocephalus.

Area of Science:

• Neurosurgery
• Pediatric Neurosurgery
• Neurology

Background:

• Obstructive hydrocephalus is a condition requiring intervention to manage cerebrospinal fluid (CSF) pathway obstruction.
• Ventriculoperitoneal (VP) shunt has been a traditional treatment, but carries risks and complications.
• Endoscopic Third Ventriculostomy (ETV) presents a less invasive alternative for specific types of hydrocephalus.

Purpose of the Study:

• To evaluate the efficacy and safety of Endoscopic Third Ventriculostomy (ETV) in patients with obstructive hydrocephalus.
• To compare ETV outcomes in different age groups: infants/young children versus older children/adults.
• To assess ETV as an alternative to VP shunt for managing CSF pathway obstruction.

Main Methods:

• Forty-three ETV procedures were performed in 46 patients diagnosed with obstructive hydrocephalus.
• Patients were divided into two groups: Group 1 (29 children < 2 years) and Group 2 (17 patients > 2 years, adolescents, adults).
• Clinical and radiological outcomes were assessed for both groups to determine treatment success and complications.

Main Results:

• Group 1 (< 2 years) achieved 70% clinical and 63% radiological improvement.
• Group 2 (> 2 years) demonstrated higher success rates with 100% clinical and 73% radiological improvement.
• ETV failed in eight patients, who subsequently benefited from VP shunt; one unrelated postoperative death occurred.

Conclusions:

• ETV is a viable and effective alternative to VP shunt for obstructive hydrocephalus, particularly in older pediatric and adult populations.
• While ETV shows promising results, VP shunt remains a necessary option for cases where ETV is unsuccessful.
• The study highlights ETV's potential to improve CSF flow and reduce reliance on shunts in managing hydrocephalus.
