    Abstract:
    One of the major problems associated with bare nitinol stent implantation is stent fracture, particularly in the popliteal artery. The purpose of this study was to determine whether drug coated balloons (DCB), interwoven stents (IWS), or plain old balloon angioplasty (POBA) would be suitable for use in distal femoropopliteal (FP) long lesions when an Eluvia stent was implanted proximal to a lesion. This was a multi-center retrospective study enrolling patients undergoing concomitant use of Eluvia with DCB, IWS or POBA for symptomatic atherosclerotic femoropopliteal disease (lesion length > 15 cm) [Rutherford category 2-6] between January 2018 and September 2021. 79 patients with 89 femoropopliteal lesions were enrolled in this study. The mean lesion length and the percentage of the popliteal artery involvement was 24.3 ± 6.4 cm vs 24.0 ± 9.0 cm vs 26.6 ± 6.2 cm and 65.8% vs 89.4% vs 67.8% for the Eluvia + DCB, Eluvia + IWS, and Eluvia + POBA groups, respectively. The 1-year Kaplan-Meier estimates of primary patency and freedom from major adverse limb events (MALEs) were 53.3% vs 44.1% vs 24.2% and 62.4% vs 51.0% vs 28.1%, respectively. Eluvia + POBA was associated with a lower rate for 1-year primary patency (HR 2.49; 95% confidence interval (CI): 1.28-4.87; p = 0.007 and HR 2.38; 95% CI: 1.13-5.77; p = 0.04). In SFA long lesions with proximal Eluvia implantation, distal implantations of either a DCB or IWS were comparable, as opposed to POBA alone which generated worse results.
