Bilateral carotid artery occlusion with concurrent basilar apex aneurysm is extremely rare 1. When it occurs, the brain blood supply mainly relies on thevertebral artery through the basilar artery. The unnatural reliance on this route is such that the pressure inside the apex of the basilar artery makes it vulnerable to aneurysm 2-4. These need to be treated quickly, as they may cause hemorrhaging and subsequent death 3,5. Craniotomy is one approach to treat patients with basilar apex aneurysm. However, in the case of a bilateral carotid artery occlusion, the increased blood pressure in the basilar artery leads to higher risks in the surgical clipping of aneurysms 3,6. The alternative approach is the endovascular treatment that has been developed since 1991 7,8. It is performed with the guidance of DSA, for accurate localization during surgery with minimal tissue damage. Here we report a case of successful treatment of bilateral carotid artery occlusion with concurrent basilar apex aneurysm using the endovascular approach. In addition, we reviewed six similar cases found through a PUBMED database search for the years 1980-2010, including cases with bilateral common carotid artery occlusion. These cases further supported the application of endovascular treatment for bilateral carotid artery occlusion with concurrent basilar apex aneurysm.
