Abstract

OLIVEIRA, Giuliano da Paz; SOARES, Nara Lívia Rezende; OLIVEIRA, Germano da Paz  and  VALE, Benjamim Pessoa. Bilateral internal carotid artery agenesis: a case report. J. vasc. bras. [online]. 2014, vol.13, n.4, pp.336-339. ISSN 1677-5449.  http://dx.doi.org/10.1590/1677-5449.0046.

Agenesis of the internal carotid artery (ICA) is defined as a congenital absence of the carotid canal and occurs in less than 0.01% of the population. This anomaly is usually diagnosed as an incidental finding or after a cerebrovascular event. We present the case of a 36-year-old woman, with bilateral agenesis of the ICA who had suffered a subarachnoid hemorrhage due to ruptured aneurysm of the basilar artery. Therefore, agenesis of the ICA is a condition that, although rare, should be considered since there is a risk of coexistence with other life-threatening conditions such as aneurysms.

Keywords : internal carotid artery; carotid artery diseases; intracranial aneurysm.
