Endovascular Repair of Interrupted Aortic Arch: Approach with Hope for Fewer Complications.

Interrupted aortic arch (IAA) is a rare congenital malformation defined as complete discontinuity between ascending and descending parts of aorta. We present a case of IAA, which was referred to us due to dilatation of proximal and mid parts of his thoracic aorta accompanied by narrowing of aorta proximal to the branching of the left subclavian artery. Further evaluation revealed interruption of aorta at the proximal part of descending thoracic aorta by a transverse septum along with several collateral formations. In general, the standard treatment of IAA is open surgical repair. Endovascular repair of IAA is an alternative approach for IAA, which is applied when two distinct parts of aorta are too close to each other. Here, we present a new approach of endovascular transcatheter repair of IAA with implantation of a self-expandable stent that we believe has fewer complications.
