This state-of-the-art review and updated systematic review and meta-analysis examines drug-eluting resorbable scaffolds (DRS) for below-the-knee peripheral artery disease, drawing on prospective and observational studies of polymer- and magnesium alloy-based devices. The review describes favorable reported patency, wound-healing, and limb-salvage outcomes in patients with advanced infrapopliteal disease. It also highlights randomized evidence from the LIFE-BTK trial, in which DRS-treated lesions had superior patency and fewer revascularizations than lesions treated with plain balloon angioplasty. The abstract does not provide quantitative effect estimates.
Key findings
- Prospective and observational studies reported favorable patency, wound healing, and limb salvage with polymer- and magnesium alloy-based DRS.
- In the LIFE-BTK randomized trial, DRS showed superior patency and reduced revascularization rates compared with plain balloon angioplasty.
Why it matters
Infrapopliteal PAD treatment must address restenosis and the consequences of permanent implants while preserving options for future revascularization. DRS are designed to provide temporary support and localized drug delivery before resorption. The review brings together evidence on these devices and highlights randomized comparison with balloon angioplasty, helping clinicians understand the potential role and current evidence base for this approach.
What to keep in mind
The abstract provides no quantitative effect estimates or details on study quality, follow-up, or the meta-analysis results, limiting assessment of the magnitude and certainty of benefit.
