ABSTRACT
Takayasu Arteritis causes annuloaortic ectasia and coronary ostial stenosis, which may necessitate open heart surgery. However, pseudoaneurysms are sometimes observed postoperatively, making subsequent treatment difficult. We report thoracic endovascular aortic repair of a pseudoaneurysm of the ascending aorta with an anastomosis of the great saphenous vein in a 61-year-old female with a history of multiple open-heart procedures. Thirty years earlier, she underwent aortic valve replacement and coronary artery bypass surgery for aortic regurgitation, and right coronary ostial stenosis. Eleven years after surgery, an ascending aortic aneurysm was found and Bentall's surgery was performed. Multiple open thoracotomies were subsequently performed. Postoperatively, a pseudoaneurysm was found at the anastomosis between the ascending aorta and the great saphenous vein. The patient was transferred to the emergency room owing to hemoptysis and was diagnosed with a ruptured pseudoaneurysm at the anastomosis of the ascending aorta and the great saphenous vein. By inserting a stent graft into the ascending aorta, we avoided further complications and her prognosis was good. She was discharged on postoperative day 18 and did not experience any end leak for a year. Thoracic endovascular aortic repair in the ascending aorta is a minimally invasive procedure that may be useful for high-risk patients.
