Cerebral Revascularization in Skull Base Tumors

ABSTRACT

Skull base tumors involving the carotid artery pose a difficult surgical challenge. The potential for bypass grafting for cerebral revascularization carries inherent risks but may aid in tumor resection and control in those who warrant carotid sacrifice but have inappropriate natural cerebrovascular reserve. We include a review of the literature discussing the indications for carotid resection as part of skull base tumor surgery, indications for cerebral revascularization, balloon test occlusion, graft types and operative technique, complications, and results.

KEYWORDS

Skull base tumor - carotid occlusion - revascularization - saphenous vein bypass graft - radial artery bypass graft
