The use of the GORE® TIGRIS® Vascular Stent with dual component design in the superficial femoral and popliteal arteries at 6 months (original) (raw)

PubMed, 2013

Abstract

Aim: The aim of this study was to collect procedural and clinical data assessing safety and performance of the GORE® TIGRIS® Vascular Stent, a novel dual component stent, made of a nitinol wire frame combined with a fluoropolymer-interconnecting structure. Methods: This retrospective analysis included 32 consecutive patients (20 men, mean age 72.8 years) with 40 atherosclerotic femoropopliteal lesions (occlusions in 5%) who underwent angioplasty and implantation of a GORE® TIGRIS® Vascular Stent. The patients were scheduled for follow-up at 3, 6 and 12 months after stent implantation for Duplex ultrasound and assessment of Rutherford Becker class (RBC) and Ankle-Brachial Index (ABI) RESULTS: The mean implanted stent length was 62.3 mm (range 30-100 mm). Procedural success (residual stenosis <30%) was achieved in 100% of the lesions. At 6 months 2 restenosis in 2 patients were observed, resulting in a cumulative primary patency rate (±standard error) of 91.7±8.0%. Between baseline and 6 months the ABI increased from 0.65±0.18 to 0.96±0.12 (P<0.0001) and the median of RBC increased from 3 to 1.5 (P<0.0005). No stent thrombosis was found. Conclusion: In this retrospective collection of patients all lesions could be successfully treated with this novel hybrid TIGRIS stent. These preliminary results show promising primary patency rates at 6 months. In addition, significant improvements were observed in symptom classification and hemodynamics.
