Endovascular Aortic Fenestration and Stent Graft Placement after Inadvertent False Lumen Deployment of a Frozen Elephant Trunk

Abstract

A 48-year-old man with Stanford type A acute aortic dissection underwent emergent total arch replacement with frozen elephant trunk (FET). Postoperative computed tomography showed inadvertent deployment of the FET into the false lumen. We therefore performed endovascular fenestration of the dissection flap and distal extension of the stent graft into the true lumen, which resulted in a thrombosed false lumen in the proximal descending thoracic aorta. Endovascular fenestration of the dissection flap and distal extension of the stent graft can be an effective bailout procedure for inadvertent deployment of the FET into the false lumen.
