Impact of below-the-knee runoff in patients undergoing drug-coated balloon angioplasty for femoropopliteal disease: a propensity score-matched analysis.

ABSTRACT:

Background

In a real-world setting, the impact of below-the-knee (BTK) runoff status on outcomes following drug-coated balloon (DCB) treatment for femoropopliteal (FP) lesions remains insufficiently studied, and robust evidence is still lacking.

Methods

Between 2021 and 2024, a total of 1,574 patients undergoing drug-coated balloon (DCB) treatment for femoropopliteal arterial occlusive disease were retrospectively identified from 9 centers in China. Propensity score matching was applied to minimize baseline imbalances, resulting in 155 matched pairs for subsequent analysis. Outcome measures included 12-month amputation-free survival (AFS), freedom from clinically driven target lesion revascularization (CD-TLR), all-cause mortality, major adverse event rate, and amputation ra
