Summary

The nitinol stent has proven superior primary patency than balloon angioplasty in superficial femoral artery lesions. Recent stent design improvements focus on decreasing stent fracture rates which can negatively impact patency rates by rearranging strut alignment. In the literature, however, prospective, randomized, controlled, clinical trial for comparison of stent fracture and primary patency between different nitinol stents has never been performed except one study; SMART versus Luminexx stent named SuperSL trial. LifeStent is similar to S.M.A.R.T. stent in the design consisted of the peak-to-valley connected with S-shaped bridge but is different in lesser bridge (4 bridge vs. 6 bridge), large cell size on stent ends, and larger cell size than S.M.A.R.T. On the other hand, Recent meta-analysis has shown that the efficaty of cilostazol in the atherosclerotic femoropopliteal lesion was proven. However, still specific data regarding a variety of antiplatelet regimen in implanted femoropopliteal lesion are limited. Upto date, in the literature, never has never been performed the clinical trial for optimal duration of cilostazol use in the patient undergone stent implantation for femoropopliteal lesion. Thus, The purpose of our study is to examine and compare Primary patency and stent fracture between different two-nitinol stents (S.M.A.R.T. CONTROL versus Lifestent) in femoropopliteal arterial lesion and to examine and compare the optimal duration of cilostazol use.

DEVICE

S.M.A.R.T CONTROL Stent

Provisional stenting should be performed; the case that optimal ballooning response is not obtained (sub-optimal balloon response) should be enrolled. The procedure is usually done, as follows; After the guidewire is passed through the target lesion, predilation of the target lesion with an optimally sized balloon will be performed prior to stent implantation. Recommended, minimal balloon dilation time is 120 seconds. The sub-optimal balloon response is defined as a residual pressure gradient of \>15 mmHg, residual stenosis of \>30%, and flow-limiting dissection.
