    Factors associated with patency following drug-coated balloon angioplasty of hemodialysis access by Guijun Huo, Jianhui Xue, Jin Zheng, Yao Tang, Dayong Zhou

    Published 2025-06-01
    “…The secondary patency rates at 6, 12, 18, 24, 30 and 36 months were 98.8%, 93.8%, 89.8%, 81.9%, 76.1% and 48.6%, respectively. Multivariate analysis using Cox proportional hazard regression models showed that lesion length>4 cm(p=0.002), tandem stenosis(p=0.007) and thrombosis (p < 0.001) were independent risk factors for primary patency after DCBA in patients with AVF. …”
