    Area of Science:

    • Nephrology
    • Vascular Surgery
    • Biomedical Engineering

    Background:

    • Hemodialysis necessitates consistent, high-flow vascular access, often achieved via arteriovenous fistulas.
    • Vascular access dysfunction, including thrombosis and infection, presents significant challenges for end-stage renal disease (ESRD) patients.
    • Current access methods highlight the critical need for reliable circulatory access in hemodialysis.

    Discussion:

    • This review examines the mechanisms of permanent vascular access creation for hemodialysis.
    • It details common complications associated with hemodialysis access, focusing on thrombosis and infection.
    • The article evaluates existing strategies and introduces novel approaches to manage these complications.

    Key Insights:

    • Arteriovenous fistulas are the preferred long-term hemodialysis access, yet remain susceptible to dysfunction.
