Endovascular Treatment of Bilateral Carotid Artery Occlusion with Concurrent Basilar Apex Aneurysm: A Case Report and Literature Review

Abstract

We report a case of successful endovascular treatment of bilateral carotid artery occlusion with concurrent basilar apex aneurysm. An elderly female patient with subarachnoid hemorrhage (SAH) onset was admitted to the hospital. Computed tomography (CT) and digital subtraction angiography (DSA) confirmed the presence of bilateral carotid artery occlusion with concurrent basilar apex aneurysm. Brain blood supply was provided by the bilateral vertebral artery through the basilar artery. We treated the aneurysm with the endovascular approach by embolizing the aneurysm with three coils. The patient recovered well after surgery and showed no recanalization of the aneurysm on a one-year follow-up DSA. We also reviewed six similar cases found with a PUBMED database search (1980-2010), including those with bilateral common carotid artery occlusion. In conclusion, by using the endovascular approach, bilateral carotid artery occlusion with concurrent basilar apex aneurysm was efficiently treated.</p
