Debulking plus drug-coated balloon combination as revascularization strategy for complex femoropopliteal lesions

Area of Science:

• Vascular Surgery
• Interventional Cardiology
• Medical Device Technology

Background:

• Drug-coated balloons (DCB) and atherectomy are key treatments for femoropopliteal artery disease.
• Both therapies have limitations and varying success rates in complex lesions.
• Optimal treatment strategies for complex femoropopliteal lesions remain under investigation.

Purpose of the Study:

• To review recent randomized trials and registries for DCB and atherectomy.
• To discuss the drawbacks of DCB and atherectomy as monotherapies.
• To evaluate the efficacy of combination therapy (atherectomy followed by DCB) in complex femoropopliteal lesions.

Main Methods:

• Analysis of data from recent randomized controlled trials.
• Review of findings from large patient registries.
• Synthesis of evidence on monotherapy and combination therapy outcomes.

Main Results:

• Some studies suggest combination therapy improves outcomes in complex, calcified femoropopliteal lesions.
• However, a key randomized pilot study did not show mid-term benefits for combination therapy.
• Drawbacks of both DCB and atherectomy as standalone treatments were identified.

Conclusions:

• The role of atherectomy followed by DCB angioplasty in complex femoropopliteal lesions requires further investigation.
• Larger, well-designed randomized studies are necessary to definitively establish the benefit of combination therapy.
• Current evidence is mixed, highlighting the need for more robust clinical data.
