Comparative Analysis of Anterior Petrosectomy and Transcavernous Approaches to Retrosellar and Upper Clival Basilar Artery Aneurysms

Abstract

From an anatomic standpoint, the TcA offers more advantages than the AP, when approaching retrosellar BA aneurysms, except for those cases in which proximal control is the principal issue and the neck of the aneurysm is located more than 6.0 mm below the floor of the sella.
