Seven patients who underwent femoral-femoral by pass between June 1980 and September 1982 underwent pre-operative angiography and pre and post-operative non-invasive evaluation to determine: (1) the hemodynamic effects created by the crossover graft, and (2) if angiographic findings would be predicative of post-operative results. The mean ankle/arm (a/a) index in the donor extremity changed from 0.82 +/- 0.20 to 0.70 +/- 0.27 (NS). The a/a index in the recipient extremity increased from 0.39 +/- 0.30 to 0.74 +/- (p less than 0.02). One patient developed a "steal" syndrome. There was no correlation between angiographic findings and post-operative changes. This study demonstrated a significant increase in recipient extremity ankle pressure and a clinically insignificant decrease in donor limb pressure.
1980年6月至1982年9月期间接受股-股旁路手术的7例患者进行了术前血管造影以及术前和术后的非侵入性评估，以确定：（1）交叉移植所产生的血流动力学效应，以及（2）血管造影结果是否可预测术后结果。供体肢体的平均踝/臂（a/a）指数从0.82±0.20变为0.70±0.27（无显著性差异）。受体肢体的a/a指数从0.39±0.30增加到0.74±（p<0.02）。1例患者出现“窃血”综合征。血管造影结果与术后变化之间无相关性。本研究表明，受体肢体踝压显著升高，而供体肢体压力的降低在临床上无显著意义。
