Endovascular fenestration of aortic dissection membrane after failed frozen elephant trunk procedure.

ABSTRACT

We report a case of a 51-year-old male with complicated acute type A aortic dissection who initially underwent a supracoronary and aortic arch replacement using frozen elephant trunk technique. False-lumen perfusion was revealed later which resulted in the collapse of the true lumen. Endovascular fenestration of the dissection flap was performed. True-lumen reperfusion with false-lumen regression was achieved. Endovascular fenestration using a re-entry catheter represents an efficient and safe treatment approach for this rare but serious complication.
