Dissected thoracoabdominal aortic aneurysm repair with modified parallel endografting.

A 67-year-old woman with a prior history of aortic dissection was admitted for enlarging the thoracoabdominal aortic aneurysm (TAAA). She has received multiple treatments including Bentall procedure, hemiarch replacement, and subsequent endovascular procedures for the closure of re-entry. Preoperative computed tomography revealed previously implanted thoracic endograft from distal arch to superior mesenteric artery with dissected TAAA measuring up to 70 mm in diameter. Re-entry was observed at bilateral common iliac arteries. The patient was successfully treated by endovascular treatment using a fenestrated stent graft to obtain a landing zone for parallel endograft technique to the iliac arteries for the closure of re-entry.
