註釋Abstract: Background
Long-term data on drug-coated balloon (DCB) outcomes in complex femoropopliteal atherosclerotic lesions are limited.

Objectives
The authors sought to report 5-year safety and effectiveness outcomes of a paclitaxel DCB for the treatment of de novo in-stent restenosis (ISR), long lesions (LL), or chronic total occlusions (CTOs) in the prespecified imaging cohorts of the IN.PACT Global Study.

Methods
The IN.PACT Global study was a prospective, international single-arm study. Assessments through 5 years included freedom from clinically driven target lesion revascularization (CD-TLR), a safety composite (freedom from device- and procedure-related death to 30 days, and freedom from major target limb amputation and freedom from clinically driven target vessel revascularization within 60 months), and major adverse events.

Results
The prespecified imaging cohorts enrolled 132 de novo ISR, 158 LL, and 127 CTO participants. Kaplan-Meier estimates of freedom from CD-TLR through 5 years were 58.0% (ISR), 67.3% (LL), and 69.8% (CTO). The cumulative incidences of the composite safety endpoint were 56.0% (ISR), 65.7% (LL), and 69.8% (CTO). The 5-year freedom from all-cause mortality with vital status update were 81.4% (ISR), 75.2% (LL), and 78.2% (CTO). Within the ISR cohort, 15.9% of participants experienced 2 or more TLRs, compared with 9.5% and 5.5% in the LL and CTO groups, respectively.

Conclusions
Results demonstrate long-term safety and effectiveness of this DCB in all 3 cohorts, with low reintervention rates in the LL and CTO cohorts and no safety issues. These results support the inclusion of this DCB into the treatment algorithm for complex femoropopliteal disease
