BACKGROUND: The superficial femoral and popliteal artery (SFPA) tract regularly experiences lateral and longitudinal significant wall stress.
In case of stent placement, strain is responsible of mesh rupture leading to restenosis. Aim of this report is to analyze short and mid-term results of Gore® Tigris® stent employment in patients with peripheral artery disease (PAD) at the SFPA.
METHODS: From September 2012 to May 2015, 27 patients (20 male, mean age 70 years) underwent percutaneous angioplasty at the femoralpopliteal tract with use of Gore® Tigris® stent. We analyze patient groups, risk factors, lesion morphology and stent employment recommendations. Patient follow up involves evaluation at one, 3, 6, 9 and 12 months.
RESULTS : Stent placement procedure was successful in all cases, with 15.7 cm average arterial covering. Mean follow up was 17.8 months (2-32 months). Four patients had stent thrombosis respectively at 45 days (above-knee amputation), at 6 months (femoral-tibial vein bypass) and two at nine months, treated conservatively. Mean functional class improved from three to one according to Rutherford scale. Primary potency at 30 months is 80%.
CONCLUSIONS: This new-generation heparin-bonded polytetrafluoroethylene (HePTFE) stent shows promising results. We expect more clinical and randomized trials with statistic assessment in order to evaluate medium and long-term results.
