    Area of Science:

    • Vascular Surgery
    • Interventional Radiology

    Background:

    • Vascular access stenosis is a common complication in patients requiring hemodialysis.
    • Early detection and effective treatment are crucial for maintaining vascular access patency.

    Purpose of the Study:

    • To evaluate the efficacy of percutaneous transluminal angioplasty (PTA) for treating vascular access stenosis.
    • To assess the impact of PTA on prolonging the survival of vascular access.

    Main Methods:

    • Retrospective analysis of 12 patients with vascular access stenosis.
    • Diagnosis confirmed by retrograde venous fistulography.
    • 13 PTA procedures were performed to dilate stenotic lesions.

    Main Results:

    • Functional success was achieved in 7 out of 13 PTA attempts.
    • Patients who underwent successful PTA experienced a significant prolongation of vascular access survival.
    • PTA demonstrated a favorable safety profile in this cohort.

    Conclusions:

    • Percutaneous transluminal angioplasty is a viable nonsurgical option for managing vascular access stenosis.
    • PTA can effectively restore patency and extend the functional life of vascular access.
    • Further research is warranted to optimize PTA techniques and patient selection.
