    Peripheral arterial transluminal dilation offers a treatment option for localized vascular disease, with a two-year success rate of 58.9%. Success is influenced by factors like iliac segment dilation and patient age, but it

    Area of Science:

    • Vascular Surgery
    • Interventional Cardiology
    • Peripheral Artery Disease

    Background:

    • Peripheral artery disease (PAD) affects millions globally, leading to claudication and limb ischemia.
    • Transluminal angioplasty is a minimally invasive option for PAD management.
    • Evaluating the long-term efficacy and predictors of success for angioplasty is crucial.

    Purpose of the Study:

    • To assess the cumulative success rate of peripheral arterial transluminal dilation.
    • To identify factors influencing the success of the procedure.
    • To analyze outcomes, including complications and residual symptoms, after dilation.

    Main Methods:

    • Prospective evaluation of 384 peripheral arterial transluminal dilations.
    • Analysis using clinical and vascular laboratory criteria.

  • Life-table method for cumulative success rate calculation.

    • Main Results:

    • Overall two-year cumulative success rate was 58.9% +/- 3.3%.
    • Higher success rates observed with iliac segment dilation, single-site dilation, claudication indication, normal distal vessels, ankle-brachial BP ratio > 0.35, and patients < 55 years.
    • Complication rate was 3.9%; worsened symptoms occurred in 8% and decreased ankle-brachial BP ratio in 23% after failed dilation.

    Conclusions:

    • Transluminal dilation is a viable option for localized peripheral vascular disease.
    • Predictors of success include specific procedural and patient characteristics.
    • While not superior to surgery, dilation plays a significant role in PAD management.
