Ruptured intracranial aneurysm associated with isolated aortic arch interruption

Abstract

Interruption of the aortic arch is a very rare congenital defect consisting of discontinuity between the ascending and descending aorta. Few patients survive to adulthood, due to effective collateral arterial flow to the descending aorta. An intracranial aneurysm is reported in only one patient with aortic arch interruption. We report a 16-year-old boy with an isolated aortic arch interruption and a ruptured anterior communicating artery aneurysm.
