Bail-out thoracic endovascular aortic repair for incorrect deployment of frozen elephant trunk into the false lumen.

We report a rare case of bail-out thoracic endovascular aortic repair after incorrect deployment of a frozen elephant trunk into the false lumen. A 54-year-old man presented to our department complaining of chest pain. Enhanced computed tomography revealed Stanford type A acute aortic dissection, which had a large entry site at the mid-descending aorta. Emergency total aortic arch replacement with a frozen elephant trunk was performed. Progressive intraoperative acidosis was observed. Immediate postoperative enhanced computed tomography showed that the distal end of the frozen elephant trunk was deployed into the false lumen through the initial tear at the proximal descending aorta. We performed emergency thoracic endovascular aortic repair through a fenestration made into the intimal flap using an Outback LTD re-entry device. The patient was discharged home on postoperative day 67 after a complete recovery.
