Type A Thoracic Aortic Dissection Following Endovascular Repair of a Common Iliac Artery Aneurysm

We discuss a rare case of acute Type A thoracic aortic dissection (TAAD) following endovascular aneurysm repair (EVAR) of a common iliac artery aneurysm, which likely resulted from complications due to aberrant anatomy. Valve replacement, ascending aortic arch graft, and entry tear suture repair were necessary to contain the TAAD. Postoperative computed tomography with angiography (CTA) demonstrated stable disease, and the patient remained asymptomatic. Open and endovascular repair of the descending abdominal aorta was avoided. Few cases in the literature report TAAD following EVAR. Detection and repair of the entry site was crucial for containing the TAAD.
