Microsurgical clipping of anterior choroidal artery aneurysms: Tips and tricks

Abstract

Anterior choroidal artery (AChoA) aneurysms are rare intracranial aneurysms which pose considerable challenge both for surgical clipping and endovascular coiling. The small size of the parent artery, variability in its point of origin from the internal carotid artery and the high rate of ischemic complications make AChoA aneurysms formidable surgical challenge. We present two cases of aneurysm highlighting the technical challenges involved in the microsurgical clipping of AChoA aneurysms.
