Bioresorbable scaffolds in lower limb arterial disease: a narrative review of advancements and future directions

Endovascular recanalization has revolutionized the treatment of peripheral artery disease (PAD), offering minimally invasive alternatives to open surgery. However, permanent metallic stents, while effective in restoring blood flow, are associated with long-term complications such as chronic inflammation, restenosis, and stent thrombosis. Bioresorbable scaffolds (BRS) have emerged as an innovative solution, providing temporary mechanical support while delivering antiproliferative drugs before ful
