Clipping of Vertebro-basilar Aneurysms by the Transoral Transclival Approach

Skull Base Approaches for Vertebro-Basilar Aneurysms

Transoral-transclival clipping of a midline vertebral artery aneurysm.

The technical advantages and possible indications for a transoral-transclival approach for low midline posterior circulation aneurysms are discussed. A case report using such a route is described. The prognosis of untreated vertebro-basilar aneurysms is briefly discussed.

Microscopic anatomy of the human vertebro-basilar system.

Concerning the structure of connective-muscular components the authors studied the walls of the terminal segments of the vertebral arteries as well as the basilar artery, utilizing the following staining methods: Azan modified by Heidenheim, Weigert's resorcin-fuchsin, and Weigert modified by van Gieson. It was established that wall of the vertebro-basilar system exhibits a mixed structure, mus...

Basilar artery fenestration associated with aneurysms treated by endovascular approach

Introduction: Arterial fenestrations are associated with saccular aneurysms that are often difficult to treat with open surgical techniques. Basilar artery fenestration reported in the literature is highly variable depending on the technique used. Typically fenestration occurs at the lower end of the basilar artery just at the vertebral arteries join. For basilar artery fenestrations associated...

Orbitozygomatic approach to basilar apex aneurysms.

Basilar apex region aneurysms are among the most complex cerebral aneurysms. They are not, however, among the most common aneurysms, and increased use of endovascular treatment has further decreased the number of patients with these lesions who undergo surgery. Nonetheless, not all basilar apex aneurysms are amenable to coil embolization, and neurosurgeons must be prepared to treat patients wit...
