RESUMEN
The fluoropolymer-coated, paclitaxel-eluting Eluvia stent has shown promising results for the endovascular treatment of femoropopliteal artery lesions in patients with claudication. The aim of the current study was to evaluate efficacy and safety outcomes of the Eluvia stent for the treatment of long femoropopliteal lesions in Asian patients. This is a single-center, retrospective study. The primary endpoint was primary patency at 1 year. Secondary outcomes were 30-days complication rate, technical success, 1-year freedom from clinically driven target lesion revascularization (CD-TLR), limb salvage, survival, amputation-free survival (AFS), wound healing, and clinical improvement. A total of 64 patients with 67 femoropopliteal lesions were included; 78% suffered from diabetes and 84% had chronic limb-threatening ischemia (CLTI). Of those with ischemic wounds, 79% did not have run-off to the foot. Mean lesion length was 193 ± 128 mm and 52% were severely calcified. Primary patency at 1 year was 84% in the overall cohort and 91% in patients with complete lesion coverage with the Eluvia stent. Technical success was achieved in 100% of the cases and 30-day complications occurred in six patients. Twelve-month freedom from CD-TLR, limb salvage, survival, and AFS were 92%, 93%, 85%, and 80%, respectively. In 80% of patients, complete wound healing was experienced and 84% had clinical improvement after 1 year. The Eluvia stent showed promising 12-month patency and clinical results for femoropopliteal treatment in this CLTI-dominant patient population with severely calcified, long lesions. Patient numbers were, however, small; larger trials are required to validate these findings. Aneurysmal change seen in some cases also needs further investigation.
