Comparison of drug-coated balloons and plain old balloon angioplasty in hemodialysis patients with Below-The-Knee artery disease.

ObjectiveTo descriptively compare the clinical outcomes of drug-coated balloons (DCB) and plain balloon angioplasty (POBA) in hemodialysis patients with Below-The-Knee (BTK) peripheral artery disease.MethodsThis retrospective study included 96 hemodialysis patients (DCB:55 POBA:41). Outcomes included changes in Rutherford grade, wound healing, freedom from target lesion revascularization (CD-TLR), survival, and amputation-free survival.ResultsBoth groups demonstrated improvement in Rutherford grade at 12 months. Wound healing occurred in 60.6% (95% CI 42.1-76.8) of the DCB group and 50.0% (95% CI 32.0-67.9) of the POBA group. Amputation-free survival was 72.7% (95% CI 59.0-83.0) with DCB and 67.7% (95% CI 52.5-80.0) with POBA. Freedom from CD-TLR was 78.9% (95% CI 65.0-88.5) for DCB and 91.6% (95% CI 79.0-97.0) for POBA. No clear between-group differences were observed.ConclusionNo significant differences were observed between DCB and POBA in this small retrospective cohort.
