The aim of this study is to examine long–term results of balloon angioplasty(BA) for femoropopliteal(FP) artery disease.
Methods and Results
From January 2004 to December 2009, a retrospective analysis was conducted of data from a multicenter study. A total of 509 patients were included. 252 patients were treated with balloon BA for de novo A/B according to the TransAtlantic Inter–Society Consensus(TASC) II classification. 257 patients were treated with stent. The outcomes were primary and secondary patency during the follow–up period and predictors associated with restenosis. Using Cox proportional–hazards model, factors through univariate analysis (P < 0.10) were entered into a multivariable analysis for association with these patency rate. In BA group, the primary and secondary patencies were 80.0% and 96.3% at 1 year, 74.8% and 95.2% at 2 years, and 62.4% and 91.7% at 4 years, respectively. In stent group, the primary and secondary patency were 69.1% and 95.3% at 1 year, 59.4% and 94.2% at 2 years, and 51.9% (p=0.002 versus BA group at same interval) and 90.6% (p=0.239) at 4 years rates. The adjusted hazard ratio of primary patency significantly associated with cerebrovascular disease, hemodialysis, and coronar artery disease were 1.66 (95% confidence interval:1.19–2.28; p=0.003), 1.67 (95% confidence interval:1.19–2.33; p=0.002), 1.47 (95% confidence interval:1.04–2.13; p=0.031).
In the TASCII A/B group, BA seems to be a valuable in the patients with FP artery disease.
