We report a rare case of surgical treatment of arteriomegaly with multiple aneurysms. The patient was a 76-year-old man who was suffering from swelling, pain, and numbness of his left lower extremity. Three-dimensional computed tomography(3D-CT)revealed arteriomegaly from the left external iliac artery to the popliteal artery with ruptured superior gluteal arterial aneurysm and superficial femoral aneurysm, and with unruptured external iliac aneurysm and popliteal aneurysm. We performed left external iliac artery―posterior tibial artery bypass, exclusion of superior gluteal aneurysm, and resection of three other aneurysms. Because of arteriomegaly, back flow from the dilated arterial branches was considerable, and the femoral artery was expanded with tension despite of distal and proxymal clamp. We therefore divided the femoral artery to avoid development of a aneurysm. The postoperative course was uneventful and 3D-CT showed good bypass flow and thrombotic occlusion of the residual femoral artery.
