概要	BACKGROUND Patients with an abdominal aortic aneurysm and long-segment iliac artery occlusion are usually treated with aorto-uni-iliac stent-graft implantation with femoro-femoral crossover bypass. However, it is more invasive than aorto-bi-iliac stent-graft implantation and poses patency issues. Herein, we describe a minimally invasive two-stage procedure of aorto-bi-iliac stent-graft implantation following iliac artery endovascular recanalization. CASE REPORT A 76-year-old man was diagnosed with an abdominal aortic aneurysm and long-segment left iliac artery occlusion. Abdominal aortic aneurysm was diagnosed during the examination of lower back pain. There were no other symptoms, including intermittent claudication. Factoring in his frail constitution and multiple comorbidities, we decided to perform aorto-bi-iliac stent-graft implantation after iliac artery endovascular recanalization to improve the patency of the left iliac artery. Aorto-bi-iliac stent-graft implantation was performed 2 days after iliac artery endovascular recanalization to avoid distal embolization. The postoperative course and 1-year follow-up were uneventful, with computed tomography revealing no endoleak and good patency. CONCLUSIONS The stent-graft implantation used in this patient is minimally invasive and results in good patency while reducing the risk of embolization. Furthermore, the long-term outcome of aorto-bi-iliac stent-graft implantation following iliac artery endovascular recanalization is more favorable than that involving treatment with aorto-uni-iliac stent-graft implantation with femoro-femoral crossover bypass.
