High Flow Bypass Surgery with a Saphenous Vein Graft

Abstract

High flow bypass (HFB) surgery is often used to treat proximal large/giant aneurysms of the intracranial carotid artery followed by a parent artery occlusion (PAO). The authors report important key techniques for successful HFB including avoidance of graft twisting, use of double insurance bypass, and the proper PAO method.
