BeGraft Peripheral PMCF Study: 12-month results

BACKGROUND: The BeGraft Peripheral PMCF study is a prospective, non-randomized study, conducted at the vascular departments of 4 hospitals in Belgium. This manuscript reports the findings up to 12-month follow-up time for the total cohort. The primary endpoint of the study is primary patency at 12 months. Primary patency is defined as a target lesion without a hemodynamically significant stenosis on Duplex ultrasound (>50%, systolic velocity ratio no greater than 2.4) and without target lesion revascularization (TLR) within 12 months. METHODS: Between June 2014 and March 2015, 70 patients with TASC II Class A (77.1%), B (14.3%), C (5.7%) or D (2.9%) aortoiliac lesions were included. The mean lesion length was 34.3 mm with a mean degree of stenosis of 83.16%. RESULTS: Primary patency rate for the total patient population was 94.4% at 12-month follow-up. Freedom from TLR at 12-month was 96.7%. CONCLUSIONS: These results confirm the already existing enthusiasm of the use of covered stents in the aorto-iliac field. Longer follow-up and more complex lesions have to be studied in the upcoming future.
