Intraoperative angioscopy may improve the outcome of in situ saphenous vein bypass grafting: a prospective study.

Objective: To find out whether intraoperative angioscopic assistance has any effect on graft outcome in patients with critical leg ischemia.

Material And Methods: One hundred one patients requiring a below-knee bypass were assigned to undergo in situ saphenous vein bypass with or without intraoperative angioscopic assistance; otherwise treated similarly including preoperative duplex vein mapping, intraoperative graft flow measurements, and angiography. Data on operative details, morbidity, hospital stay, and graft patency were collected prospectively and compared.
