We reported a first case of a 62-year-old woman have ideopathic arteriovenous fistula. Duplex scan and angiography showed an arteriovenous fistula in the brachial artery. Because ischemic symptoms increased in the left arm, we performed arteriovenous fistula resection and partial brachial artery interposition using grate saphenous vein. In postoperative course, her ischemic symptoms and blood pressure were improved.
