Superior Cerebellar Artery Aneurysm
Last Updated: September 28, 2018
Aneurysms of the posterior circulation, including superior cerebellar artery (SCA) aneurysms, present unique technical challenges because they can only be accessed via maneuvering through deep operative corridors with limited working angles bounded by critical neurovascular structures.
The posterior circulation is intimately involved with the brainstem and cranial nerves, and complications related to aneurysm treatment frequently result in clinically significant consequences.
SCA aneurysms are rare lesions with a reported incidence of 1-2% of all aneurysms. The majority of these aneurysms are located at the proximal aspect of the SCA, typically at the basilar junction. The SCA supplies the main portions of t...
