BACKGROUND: Whether intraluminal drug-coated balloon (DCB) angioplasty is superior to subintimal DCB angioplasty regarding femoropopliteal (FP) chronic total occlusion (CTO) outcomes has not been systematically determined.
OBJECTIVES: The aim of this study was to compare the 1-year clinical outcomes of intraluminal and subintimal DCB angioplasty for the treatment of patients with symptomatic FP CTO.
METHODS: This subanalysis of POPCORN (Prospective Multi-Center Registry of Drug-Coated Balloon for Femoropopliteal Disease) evaluated 469 lesions in 469 symptomatic patients with lower extremity artery disease who presented with FP CTO and underwent DCB treatment. Wire passage (intraluminal vs subintimal) was evaluated using intravascular ultrasound. The outcome measure, 1-year freedom from restenosis, was compared between subintimal and intraluminal DCB angioplasty groups after propensity score matching analysis. The Institutional Review Boards of participating centers approved this study. Informed consent was obtained from the participants or their families.
RESULTS: During the median follow-up period of 14.2 months, restenosis occurred in 140 patients. After propensity score matching, the subintimal group had a significantly lower 1-year rate of freedom from restenosis than the intraluminal group (77.0% vs 84.2%, respectively; P = 0.024). Interaction analysis revealed a more marked increased risk for restenosis in the subintimal DCB angioplasty group in patients with severe calcification, low-dose DCB use, or smoking.
CONCLUSIONS: The present study revealed that intraluminal DCB angioplasty was superior to subintimal DCB angioplasty for FP CTO treatment, with a significantly better 1-year rate of freedom from restenosis.
