Analysis of 193 femoropopliteal angioplasties demonstrated patency rates in the stenotic group of 75.5% at 6 months and 54.4% at 54 months. The patency rates for the occlusive group were 93.7% at 6 months and 72.9% at 54 months; these rates were significantly better than those in patients with stenoses. A group of 14 patients with long-segment (greater than 7 cm) stenosis had the highest risk of early failure, with a 6-month patency of 23.1%. After removal of the long-segment stenosis group from the results, there were no significant differences between the long-term patencies for stenotic and occlusive lesions. If angioplasty of long stenoses is attempted, a high initial success rate but early failure should be anticipated.
对193例股腘动脉血管成形术的分析表明，狭窄组在6个月时的通畅率为75.5%，在54个月时为54.4%。闭塞组在6个月时的通畅率为93.7%，在54个月时为72.9%；这些比率明显优于狭窄患者的比率。一组14例长段（大于7 cm）狭窄患者早期失败风险最高，6个月通畅率为23.1%。从结果中剔除长段狭窄组后，狭窄性病变和闭塞性病变的长期通畅率无显著差异。如果尝试对长段狭窄进行血管成形术，应预期初始成功率高但早期会失败。
