Vascular Disorders: Surgical Approaches and Operative Technique

Abstract

Saccular aneurysms in juveniles and adolescents are dealt with technically in the same way as in adults, though the surgeon may be confident that he will not encounter arteriosclerosis or arterosclerotic plaques. Giant aneurysms, irrespective of their location, must be resected “in toto” because of their tendency to act as tumors. Posterior inferior cerebellar artery (PICA) aneurysms are more common, and generally larger in size. The standard techniques for exposing the suprachiasmatic, parasellar, interpeduncular, and lateral medullary regions for access to anterior or posterior circle aneurysms, or aneurysms of the vertebral basilar junction, are used.
