- Abstract
- Interwoven nitinol stents (INS) and drug-eluting stents (DES) were designed to improve the mid- and long-term results of femoropopliteal (F-P) angioplasty. The aim of this study was to systematically compare these stents. Between 2015 and 2017, 62 patients with symptomatic peripheral artery disease of the F-P segment treated by INS or DES were identified from a prospectively maintained institutional database. The primary outcome measure was one-year primary patency; secondary outcomes were in-stent restenosis (ISR), stent occlusion, target lesion revascularization (TLR) and mortality. The mean follow-up was 26.9 ± 11.2 months. No statistically significant difference in primary patency at one year was observed (88.6% vs. 88.9%). Throughout follow-up, overall rates of ISR (5.7% vs. 11.1%, p = 0.645), stent occlusion (25.7% vs. 7.4%, p = 0.094) and TLR (25.7% vs. 18.5%, p = 0.505) were statistically equivalent between the groups. Mortality reached 14.3% in the INS group and 3.7% in the DES group, but this difference was not statistically significant (p=0.196). Multivariable analysis revealed significant correlations between ISR and stent occlusions; popliteal lesion localization (p = 0.016) and poor below the knee vessel outflow (p < 0.001). In the short- and mid-term, the use of an INS or DES in the F-P arterial segment did not result in a difference in primary patency rate, stent occlusion, restenosis, re-intervention or mortality. The overall data do not provide any evidence to favor one stent over the other.
