A retrospective study of 34 patients with 29 autologous vein femoropopliteal and 8 femorotibial bypasses was conducted, examining the correlation of angiographic runoff and non-invasive flow determinants as prognostic indicators of early graft occlusion of lower limb bypass grafts. The followup period was 3-27 months, with a mean of 5.8 months. Graft patency and improvement in presenting symptoms were unrelated to preoperative ankle systolic pressure indices. Preoperative and postoperative flow measurements were similar in patients with patent grafts (greater than 12 months) and in those with early graft occlusion (0-6 months, p greater than .05). Preoperative pressure indices did not correlate with calf vessel runoff (p. greater than 05). The data suggest: (1) the noninvasive flow studies are not reliable predictors of future graft patency, (2) vessel runoff is not a reliable predictor of limb flow, and (3) bypass procedures in the lower extremities should not be excluded on the basis of noninvasive flow studies when indicated by other clinical parameters.
对34例患者进行了回顾性研究，其中29例为自体静脉股腘动脉搭桥术，8例为股胫动脉搭桥术，研究血管造影显示的流出道情况与非侵入性血流指标之间的相关性，以此作为下肢搭桥移植血管早期闭塞的预后指标。随访期为3至27个月，平均为5.8个月。移植血管通畅情况及症状改善与术前踝部收缩压指数无关。移植血管通畅（超过12个月）的患者与早期移植血管闭塞（0至6个月）的患者术前和术后血流测量结果相似（p>0.05）。术前压力指数与小腿血管流出道情况无相关性（p>0.05）。数据表明：（1）非侵入性血流研究并非未来移植血管通畅情况的可靠预测指标；（2）血管流出道情况并非肢体血流的可靠预测指标；（3）当其他临床参数表明需要进行下肢搭桥手术时，不应基于非侵入性血流研究而排除该手术。
