Abstract
• Real-time B-mode ultrasound scanning was used during arterial reconstruction surgery to supplement the information of preoperative arteriography and to detect vascular defects immediately after restoration of blood flow. At 55 operations, 100 sites were examined. At three operations, ultrasound provided new information that, in two patients, directly affected the choice of operation. Intraoperative postreconstruction scanning detected vascular defects in over 20% of the patients. Intimai flaps were the commonest defects observed. In most instances in which defects were seen, the vessels were not reentered because the defects were considered to be too small or located in a nonstrategic site or both. One relatively large intimai flap in a common carotid artery prompted reentry. Ultrasound during vascular operations proved to be a highly sensitive diagnostic tool to supplement preoperative arteriography and to detect vascular defects resulting from reconstructive surgery.
