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.
