SP 208 OP 210 DO 10.1136/jnis.2009.001966 VO 2 IS 3 A1 Drazin, Doniel A1 Choulakian, Armen A1 Alexander, Michael J YR 2010 UL http://jnis.bmj.com/content/2/3/208.abstract AB In a 41-year-old woman with a ruptured anterior communicating artery aneurysm, cerebral angiography incidentally showed an absence of the right common carotid artery. The right internal and external carotid artery originated from the ipsilateral inominate artery. The absence of the common carotid artery is extremely rare and association with a ruptured cerebral aneurysm is even less common. A description of the case and review of the literature are reported.
