Treatment of Cerebral Saccular Aneurysms Located in Peripheral Arteries of the Posterior Cranial Fossa

Abstract

In most patients with cerebral aneurysms of the peripheral portion of the anterior inferior cerebellar artery or posterior inferior cerebellar artery, selective endovascular aneurysmal obliteration is very difficult. Endovascular occlusion of the parent artery may be an easier approach, but this can have potentially unfavorable clinical consequences due to ischemic complications. Here we propose aneurysmal neck clipping with preservation of blood flow in the parent artery as an ideal firstline treatment for such lesions, although expertise in microsurgical techniques and anatomical knowledge are required.
