A 16 year review of femoropopliteal bypass grafts identified five factors with significant influence on long term patency. Most important was the nature of the graft itself, with vein grafts having superior long term performance as compared to a variety of prosthetic grafts. Arteriographic runoff, indications for operation, site of the distal anastomosis and prior femoropopliteal operation had a major influence on long term patency of prosthetic grafts but rather minimal effects on the patency of autogenous vein grafts. The influence of several variables proved cumulative, leading to a favorable subset of patients in whom prosthetic grafts may approach long term performance of vein grafts. Differences in such key variables is a major contribution to the widely differing patency rates of previous studies and must be carefully controlled in any future prospective studies.
一项针对股腘动脉搭桥术的16年回顾研究确定了五个对长期通畅率有重大影响的因素。最重要的是移植物本身的性质，与各种人工血管相比，静脉移植物具有更好的长期性能。动脉造影显示的血流情况、手术指征、远端吻合口位置以及既往股腘动脉手术对人工血管的长期通畅率有重大影响，但对自体静脉移植物通畅率的影响极小。几个变量的影响被证明是累积性的，导致了一部分预后良好的患者群体，在这些患者中，人工血管的长期性能可能接近静脉移植物。这些关键变量的差异是先前研究中通畅率差异巨大的主要原因，在未来任何前瞻性研究中都必须仔细加以控制。
