PURPOSE: Evaluate the short and mid-term safety and efficacy of the EPIC™ Nitinol Vascular Stent System for the treatment of lesions located in the Superficial Femoral Artery (SFA).
METHODS: From October 2010 to June 2012, 83 subjects were enrolled in a prospective, multi-center, non-randomized study designed to demonstrate that the EPIC Nitinol Vascular Stent System for SFA lesions is non-inferior to the published patency rates found in literature. Inclusion criteria were stenosis or occlusion of the SFA or SFA and proximal popliteal artery, with total length from 4 to 11 cm and amenable for treatment with a single stent, in patients with a score from 2 to 5 on Rutherford classification. The primary endpoint was primary patency rate at 12 months as determined by duplex ultrasound. The secondary endpoints evaluated were: initial arteriographic success, primary patency rate at 6 months, major adverse event rate at 1 year and technical success. Follow-up with a complete clinical and physical exam, including ABI and Duplex ultrasound was performed at 6 and 12 months.
RESULTS: Most patients (56.6%) were men and the mean age was 68.59 (33.1 – 99.15) years. 25.3% of the total population had intermittent claudication and 73.5% presented with critical limb ischemia. Most lesions were total occlusions (75.9%) and the mean lesion length was 71.16 mm. Contralateral femoral access was performed in 26.5%cases, and ipsilateral femoral approach was used for the remaining 73.5% patients. Technical and arteriographic success was obtained in all 83 (100.00%) patients. Duplex controlled primary patency rate at 6 and 12 months was 95.8 and 76.1%, respectively. The freedom from target lesion revascularization rate was 98.7 and 92.6% at 6 and 12 months, respectively. No stent fractures were observed in this study. Major adverse event rate at 1 year (clinically driven TLR, major amputation, and all-cause mortality) was 15.7%: two target lesion revascularizations (2.4%), one major amputation (1.2%) and ten deaths not related to the procedure (12%).
CONCLUSION: In conclusion, this study demonstrates the safety and efficacy of the EPIC™ Nitinol Vascular Stent System for the treatment of SFA lesions.
