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. Intimal 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 intimal 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.
在动脉重建手术期间使用实时B超扫描，以补充术前动脉造影的信息，并在恢复血流后立即检测血管缺陷。在55例手术中，对100个部位进行了检查。在3例手术中，超声提供了新的信息，其中2例直接影响了手术方案的选择。术中重建后扫描在超过20%的患者中检测到血管缺陷。内膜瓣是最常见的观察到的缺陷。在大多数发现缺陷的情况下，血管未被重新打开，因为这些缺陷被认为太小或位于非关键部位或两者皆有。一例颈总动脉相对较大的内膜瓣促使重新打开血管。血管手术中的超声被证明是一种高度敏感的诊断工具，可补充术前动脉造影并检测重建手术导致的血管缺陷。
