Multi-detector computed tomography demonstration of double-lumen aortic arch – persistent fifth arch – as an isolated anomaly in an adult

Abstract

AbstractPersistent fifth – double-lumen – aortic arch is a rarely seen entity, which is usually associated with other cardiac anomalies; it has been previously reported only in children. We report a new case of double-lumen aortic arch with a systemic-to-systemic connection diagnosed incidentally during cardiac multi-detector computer tomography evaluation of coronary artery bypass grafts in an adult.
