Combined transpetrosal-transtentorial approach with occipital artery - anterior inferior cerebellar artery bypass and aneurysm clipping for a lower basilar artery aneurysm involving anterior inferior cerebellar artery: Two-dimensional operative video.

ABSTRACT:

Background

Aneurysms of the lower basilar artery (BA) are rare, accounting for <1% of all intracranial aneurysms. This location has been described as "No man's land" since it poses a potential challenge for microsurgery. Recently, endovascular treatment has become an alternative option; however, there are some disadvantages regarding the obliteration rate, patency of the parent, and perforating arteries.

Case description

We present the case of a 69-year-old female with an incidentally found lower BA aneurysm. The imaging examinations revealed a wide-neck aneurysm size of 8.5 mm arising just distal to the vertebrobasilar junction, with involvement of the left anterior inferior cerebellar artery (AICA). After a discussion with the patient, she opted to undergo the surgical tre
