Summary
Biodegradable stents show promise for treating peripheral arterial diseases (PAD), offering a safe and effective option. However, current evidence is limited by study design and follow-up duration, preventing guideline changes.
Area of Science:
- Vascular Surgery
- Biomaterials Science
- Medical Device Technology
Background:
- Biodegradable scaffolds offer a novel approach to vascular repair, aiming to restore vessel integrity without permanent foreign body implantation.
- This technology seeks to mitigate chronic local inflammatory responses associated with traditional permanent implants.
- Peripheral arterial diseases (PAD) represent a significant clinical challenge requiring innovative treatment solutions.
Purpose of the Study:
- To systematically review the existing literature on the efficacy and safety of biodegradable stents in treating peripheral arterial diseases (PAD).
- To evaluate the current evidence base for biodegradable scaffold use in femoropopliteal and other lower limb arterial interventions.
- To identify gaps in the research and areas for future investigation in biodegradable stent technology for PAD.
Main Methods:
- A systematic review adhering to PRISMA guidelines was conducted, including English-language publications from January 2005 to March 2015.
- Literature searches were performed in PubMed and Ovid MEDLINE using keywords such as "biodegradable scaffolds," "biodegradable stents," "peripheral arterial disease," and "femoral."
- Eligible studies included those evaluating biodegradable scaffolds or stents for PAD treatment, with ongoing trials also examined.
Main Results:
- Six eligible studies involving 325 stents in 282 patients were included in the qualitative analysis.
- Technical success rates for biodegradable stent implantation were 100%.
- Short to medium-term follow-up (up to 58 months) revealed primary patency rates of 60.8% and secondary patency rates of 88.4%.
Conclusions:
- Current literature suggests biodegradable scaffolds are safe and effective for PAD treatment.
- However, the evidence is limited by study heterogeneity, small sample sizes, and short follow-up periods.
- Higher-level evidence is required to demonstrate superiority and influence current clinical practice guidelines for PAD management.
