Middle Meningeal Artery to Premeatal Anterior Inferior Cerebellar Artery Bypass via Anterior Petrosectomy: An Anatomic Feasibility Study

摘要

BACKGROUND: Anterior inferior cerebellar artery (AICA) aneurysms are rare with no optimal consensus on management strategies. When treatment requires parent artery occlusion, postoperative ischemic or neuropathic complications can occur. This study evaluated the feasibility of direct revascularization of premeatal AICA using the middle meningeal artery (MMA) as the donor through an anterior petrosectomy window.
