Abstract
Reporting outcomes with a new generation paclitaxel eluting balloon (Luminor®; iVascular, Vascular, S.L.U., Barcelona, Spain) in the popliteal district. Endovascular treatment of popliteal artery atherosclerotic disease is still debated without definitive evidences. From January to June 2019, patients' data presenting popliteal artery atherosclerotic diseases and treated with the Luminor® (iVascular) drug eluting balloon (DEB) were prospectively collected. Critical limb ischemia (CLI) or severe claudication associated with popliteal artery stenosis >50% were the inclusion criteria. Measured outcomes were technical success, early and late results; including mortality, morbidity, symptoms recurrence, amputation, ankle-brachial index (ABI), survival, primary patency, secondary patency, freedom from restenosis. Median follow-up was 22.43 ± 4 (mean:21.58; IQR:20-24) months. Of the 33 included patients, 28 (85%) were diagnosed with CLI, with a mean preoperative run-off score of 5.39 (r:0-10; SD:3) and a chronic popliteal occlusion in 21 (64%). Technical success was achieved in all cases. Perioperative mortality was observed in 1 (3%) patient and perioperative complications in 2 (6%). During the follow-up were reported 2 symptoms recurrence; a significant ABI increase (0.57; IQR:0.41-0.47 vs. 0.69; IQR:0.50-0.67; P < 0.01); 1 (3%) major and 2 (6%) minor amputations. Estimated 24 months survival, primary patency, secondary patency, and freedom from restenosis were 97%, 96.9%, 100%, and 93.8% respectively. In this prospective study, the use of the Luminor® (iVascular) was safe and effective in addressing atherosclerotic popliteal artery lesions. Larger studies with longer term-outcomes are required to assess the durability of this device in the popliteal artery.
