Abstract

AIMS:

To examine the efficacy and durability of an interwoven self-expanding nitinol stent in the treatment of complex femoropopliteal artery lesions in unselected patients.

METHODS AND RESULTS:

Five hundred and twenty-seven limbs in 470 patients with femoropopliteal arterial disease were treated with SUPERA stents. Follow-up data were prospectively collected in a single-centre registry and were available for 439 patients (492 limbs). The patients were followed by Doppler ultrasound, stent roentgenograms, estimation of Rutherford-Becker class (RBC) and ankle-brachial index (ABI). Total occlusions were present in 277 limbs (52.6%) and 52.4% had either moderate or severe calcification. The mean lesion length was 126.4 mm. The primary patency (PP) rates were 83.3% after 12 months and 72.8% at two years. The secondary patency rates were 98.1% after 12 months and 92.0% at two years. Patency rates did not differ between superficial femoral artery (SFA) and popliteal lesions. Between baseline and a mean of 21 months of follow-up, mean ABI increased from 0.53 to 0.91, and mean RBC decreased from 3.0 to 1.9 (p<0.001 for both comparisons). Radiographs performed on 229 patients at a mean of 16.6 months confirmed the absence of stent fractures in all patients.

CONCLUSIONS:

Over a two-year surveillance period, the patency rate and fracture resistance of SUPERA stents implanted for complex femoropopliteal artery disease were high.
