Wide opening of the uvulo-tonsillar space to facilitate early intraoperative control of feeding arteries in fourth ventricular tumor surgery: How I do it
The aim is to outline a technique for early control of feeding arteries during fourth ventricular tumor surgery.
Utilized wide opening of the uvulo-tonsillar space
Focused on early interruption of posterior inferior cerebellar artery (PICA) feeders
Performed during surgical treatment of fourth ventricular tumors
Achieved safe devascularization of tumors with significant arterial supply
Allowed effective management of feeding arteries during surgery
Abstract
This technique enables early interruption of PICA feeders, allowing safe and effective devascularization of fourth ventricular tumors with abundant arterial supply.
