- Abstract: An 85-year-old man being treated for idiopathic interstitial pneumonia underwent chest CT 6 months prior to the current admission and was diagnosed as having an expanding saccular aneurysm of the aortic arch. Due to the patient's advanced age and the anatomical position of the aneurysm, it was difficult to perform total aortic arch replacement or hybrid arch repair with a commercially available device. After ethical approval had been obtained from the institutional review board, a commercially available stent graft (Relay Plus®) was fenestrated with a 12-mm hole. Under general anesthesia, bypass grafting was performed between the bilateral axillary arteries and the right common carotid artery with a T-shaped ring-supported e-PTFE prosthesis. The fenestrated stent graft was advanced through the left femoral artery and deployed with the device fenestration located at the bifurcation of the brachiocephalic artery. Then, a branched stent graft was deployed through the right common carotid artery in a retrograde manner between the brachiocephalic artery and the ascending aorta through the fenestration to complete the procedure. The patient had an uneventful postoperative course, with no detectable endoleak on postoperative digital subtraction angiography. The current technique, involving the use of an easy-to-make device，is effective for endovascular aneurysm repair, especially when a proximal neck needs to be created in the ascending aorta.
