Abstract
Radiation therapy for cancer sometimes causes vascular occlusion, and is known as radiation arteritis. We report two successfully treated cases of suspected radiation arteritis with intermitted claudication. In both cases artery reconstruction was performed by avoiding direct incision, because it was reported that direct incision to radiated area had a high complication rate. Case 1 was a 53-year-old man, who had received irradiation for testicular seminoma at the age of 35. The occlusion was located in the right external iliac artery and we performed extra-anatomical bypass. Case 2 was a 59-year-old woman, who had received the irradiation for uterine carcinoma at the age of 40. The occlusions were located in bilateral external iliac arteries and we performed percutaneous trasluminal angioplasty with stenting. Both had an uneventful postoperative course and no postprocedured intermittent claudication after procedure.
