Learning objectives
Upon completing this education exhibit,
the user will be familiar with the postoperative appearance of endoscopic third ventriculostomy (ETV) and how to assess its anatomic and functional patency and what to look for regarding complications.
Background
Following endoscopic third ventriculostomy (ETV),
computed tomography (CT) and magnetic resonance imaging (MRI) are the most valuable tool for the non-invasive evaluation of the post-operative patient.
CT and MRI can be utilized to accurately describe surgical complications and to monitor the patency and efficacy of the ventriculostomy.
Findings and procedure details
Introduction:
Endoscopic third ventriculostomy (ETV) is a neuorsurgical procedure performed for obstructive hydrocephalus where a near physiologic CSF circulation is restored by making a permanent defect in the floor of the third ventricle anterior to the mammillary bodies,
thus connecting it to the interpeduncular.
The overall complication rates reported in published series varies widely from 4–30%,
but the overall rate of serious complications is less than 10% including an infection rate of 3%,
and hemorrhage rate 2.5%.
Late failure occurs in up to 40%.
Anatomical...
Conclusion
CT and MRI provides excellent noninvasive postoperative evaluation of ETV providing important pertinent information on its patency (anatomically and functionally) and post-operative complications.
