[Simultaneous Repair for Aorto-iliac Occlusive Disease and Transcatheter Aortic Valve Implantation;Report of a Case].

: A 79-year-old womam presented with severe aortic stenosis (AS) and aorto-iliac occlusive disease (AIOD). The distal end of her abdominal aorta was occluded with severe calcification. Simultaneous Y-grafting of the terminal abdominal aorta and transcatheter aortic valve implantation (TAVI) using the left limb of a Y-shaped artificial graft as an access route were planned. After proximal and distal anastomoses of the abdominal aorta and the right common iliac artery(CIA) using the Y-shaped artificial graft, TAVI was performed through the left limb of the artificial graft. The technique was similar to that used for transfemoral TAVI. Subsequently, the left limb of the graft was anastomosed to the left CIA. The patient's postoperative course was unremarkable, without heart failure or lower limb ischemia. This option serves as an effective access route for TAVI in patients with AIOD.
