Abstract

Nonvisualization of the internal carotid artery (ICA) on cross-sectional imaging studies can be due to congenital (dysgenesis of the ICA) or acquired (complete occlusion of ICA) causes. We report two cases, one with absent carotid canal on bone window setting of computed tomography (CT) suggestive of congenital cause and the other with normal carotid canal, suggesting acquired cause. Development of aortic arches with six pathways of collateral circulation in brain is also discussed.

摘要

横断面影像学检查中颈内动脉（ICA）不显影可能是由于先天性（ICA发育不全）或后天性（ICA完全闭塞）原因所致。我们报告两例病例，一例在计算机断层扫描（CT）的骨窗设置上显示颈动脉管缺如，提示先天性原因；另一例颈动脉管正常，提示后天性原因。本文还讨论了具有六条脑侧支循环途径的主动脉弓的发育情况。
