Direct cover-clip for ICA blood blister-like aneurysm

Abstract

Blood blister aneurysm (BBA) is the aneurysm characterized by fragile neck usually arising from the dorsal wall of internal carotid artery (ICA). Application of aneurysm clip on the neck of BBA usually tears out the wall of the parent artery, leaving a defect on ICA. Trapping of ICA or fail to control bleeding may cause death of patient. Although various surgical procedures were proposed, there is no consensus with regard to the best option for the treatment of BBA. Direct clipping is a simple and fast way to treat BBA, which avoids long time temporary occlusion of ICA, prevents the occurrence of brain ischemia, and provide direct observation of clipping under microscope. We report a rescue technique direct “cover-clip” for intraoperative rupture of BBA in this paper. Keywords: BBA, Direct clip, Cover-clip
