Abstract

A 71-year-old man underwent thoracic endovascular aortic repair (TEVAR). His postoperative course was uneventful, with no endoleak by enhanced computed tomography (CT). CT performed 3 months postoperatively showed stent graft stenosis. The patient was readmitted to the hospital, and balloon dilation was performed for stent graft stenosis. During the procedure, obstruction of abdominal aorta and left renal artery developed secondary to thrombus expressed from the aneurysm in response to balloon dilation. The patient subsequently underwent immediate thrombectomy using a Fogarty catheter. While reperfusion was obtained, partial thrombus remained in the right common iliac artery. After thrombectomy, additional TEVAR was performed to prevent further thromboembolic events. Bare stent was placed in the right iliac artery on postoperative day 15, and the patient discharged on postoperative day 20 with no symptoms. We conclude that treatment for stent graft stenosis should be considered carefully prior to surgery.
