Embolization of Anterior Communicating Aneurysm associated with Interrupted Aortic Arch / 신경중재치료의학

ABSTRACT

Interrupted aortic arch (IAA) is an interruption in the continuity of the aortic arch, often with a fibrous cord between the two segments. It accounts for about 1% of congenital cardiovascular defects and is differentiated from severe coarctation and aortic atresia by the absence of any structural connection (1). Survival may be prolonged because effective arterial collaterals to the descending aorta develop during fetal and postnatal life (2). Although only two cases reported a combination between IAA and an aneurysm of the circle of Willis, there is none of report in coil embolization of the same case. We describe a 31-year-old patient, in whom IAA and unruptured aneurysm were discovered during angiography. Coil embolization was performed via direct puncture of the common carotid artery, which was required due to arterial tortousity and interruption.
