Occipital Artery Harvesting and Anastomosis to P3 Segment of Posterior Inferior Cerebellar Artery: Operative Video.

ABSTRACT: Aneurysms involving the origin of the posterior inferior cerebellar artery (PICA) have a greater incidence of fusiform morphology, intraluminal thrombi, and wall calcifications. At times, a complex treatment strategy with vessel occlusion and revascularization using a bypass graft is necessary for successful obliteration of these aneurysms. The occipital artery (OA) is often the preferred donor graft for lesions of the posterior fossa because of its proximity to the target recipient vessels. However, dissection of an OA can be challenging, given its anatomically tortuous path and the presence of thick surrounding muscles. This video captures the dissection of the OA using an unconventional, "inside-out" harvesting technique and the end-to-side anastomosis of the OA to the PICA at the p3 se
