A high-position basilar top aneurysm approached via third ventricle: case report.

ABSTRACT

The authors report a subfrontal transventricular approach to a high-position basilar top aneurysm considered to be inaccessible by conventional pterional or subtemporal techniques. This special technique may be preferred in the case where a megadolichobasilar artery coexists with such an aneurysm as it has the advantage of protecting the brain from the detrimental effects of strong retraction.
