Abstract 13591: Durability of S.M.A.R.T. ControlTM Stent for Superficial Femoral Artery, J-SMART registry
Backgrounds: Stent deployment for superficial femoral artery (SFA) is still controversial. Although some published data reported efficacy of nitinol stent for long (≥10cm) SFA under appropriate medical therapy, there were a few long term and large scale studies Method and Result: We conducted retrospective, multicenter registry of S.M.A.R.T ControlTM deployed for de novo SFA. Four hundred and thirty-six patients and 528 lesions were studied. Mean age was 72.5±7.5 years old, and mean stent length was 15.5±8.4 cm and TASC C/D lesion were 260 lesions (49%). Four year primary patency and secondary patency was 66% and 87%. Cilostazol administration was significantly lower in restenosis group (59 vs 71%, P<0.01). Restenosis group tended to have more chronic occlusion (CTO) (72 vs 52%, P<0.01) and more female gender (74 vs 54%, P<0.01).
Conclusion: The result of S.M.A.R.T ControlTM for SFA lesion was good long term durability. Cilostazol administration, CTO, and female gender were associated with long term patency.
