Introduction
Frozen elephant trunk (FET) deployment for type A acute aortic dissection (TAAD) has been widely accepted because it induces aortic remodeling in the downstream aorta.1 FET malposition into the false lumen (FL) has rarely been reported. However, urgent intervention is required to prevent ischemic organ damage because endograft malposition has dire consequences for visceral, renal, and lower extremity perfusion.2,3 In this report, we describe the clinical features of this complication and the endovascular technique used to divert back persistent FL perfusion to the true lumen (TL) of the downstream aorta. The patient provided consent for this report.
