Background:
Vein graft stenosis is a critical complication of lower-limb bypass surgery. For vein graft stenosis, balloon angioplasty has been performed instead of surgical revision in recent years. We therefore investigated the effectiveness of the balloon angioplasty for vein graft stenosis.
Methods And Result:
We conducted a retrospective analysis of prospectively collected data for 115 vein graft stenoses performed via balloon angioplasty from August 2011 to January 2018. The rate of freedom from reintervention after balloon angioplasty was 54.3%, 44.4%, and 38.0% at 1, 2, and 3 years, respectively. The rate of freedom from graft occlusion after balloon angioplasty was 79.9%, 71.9%, and 61.3% at 1, 2, and 3 years, respectively. Predictors of freedom from graft occlusion after balloon angioplasty by a multivariate analysis were a single treated lesion (hazard ratio [HR]: 0.38; 95% confidence interval [CI]: 0.17-0.85; P = 0.0189), balloon angioplasty within 90 days after bypass surgery (HR: 3.59; 95% CI: 1.56-8.07; P = 0.0033), and using a cutting balloon (HR: 0.42; 95% CI: 0.17-0.97; P = 0.0426).
Conclusions:
The freedom from graft occlusion rate after balloon angioplasty remained relatively high. Furthermore, better results can be expected in single treated lesions and cases of balloon angioplasty occurring 90 days after bypass surgery or in which a cutting balloon was used. Balloon angioplasty for lower-limb bypass graft stenosis was shown to be a useful treatment.
