Successful Hybrid Zone 0 Landing Thoracic Endovascular Aortic Repair for Ascending Aortic Pseudoaneurysm after Bentall Procedure and Coronary Artery Bypass Grafting in Takayasu Arteritis.

Pseudoaneurysm at the suture line is one of the most common complications in aortic surgery for Takayasu arteritis (TA) and is associated with a high mortality rate. A 52-year-old man with TA, who previously underwent the Bentall procedure and 2 redo surgeries for coronary artery obstruction and a pseudoaneurysm of a coronary button, was diagnosed with an anastomotic pseudoaneurysm in the ascending aorta. Hybrid zone 0 debranching thoracic endovascular aortic repair was performed, and the patient was discharged uneventfully on postoperative day 8.
