- Abstract
- Background: Optimal stenting strategy for long femoropopliteal artery lesions still remains undefined. Longer stent length has been shown to be associated with increased risk of restenosis. We sought to compare the efficacy of spot versus long stenting in the treatment of femoropopliteal artery disease. Methods: This study was designed as a multicenter randomized controlled trial to compare immediate and mid-term outcomes of spot versus long primary stenting for femoropopliteal arterial lesions. A total of 125 patients were randomized 1: 1 to spot stenting group (n = 59) or long stenting group (n = 66). Results: All lesions were treated with self-expanding bare nitinol stents. Baseline clinical and lesion characteristics were similar between the 2 groups except for male gender and current smoker. The mean lesion length was 24.1 +/- 8.8 cm. Technical success was achieved in all patients. The 1-year primary patency and TLR-free (target lesion revascularization) survival did not differ significantly between the 2 groups. However, the spot stenting group showed a trend toward higher primary patency (86.1% vs. 72.7%, P = 0.158) and TLR-free survival (94.2% vs. 82.5%, P = 0.120). The total stented length (hazard ratio [HR] 1.01, 95% confidence interval [CI] 1.00-1.01, P = 0.011) and age (HR 0.94, 95% CI 0.90-1.00, P = 0.035) were independent predictors of restenosis. Conclusions: The spot stenting appears to be more favorable than the long stenting in terms of primary patency and TLR-free survival, although the difference was not statistically significant. The stented length was an independent predictor of restenosis.
