Dialysis Access

    Dialysis Fistula or Vascular Access Problems: When Ultrasound Helps

    Guide for AV fistula and dialysis access ultrasound when there is low flow, high pressure, arm swelling, difficult cannulation, clot concern, or pre-operative mapping.

    Why access ultrasound is requested

    Dialysis access needs enough flow and a usable vein or graft pathway. Ultrasound may be requested before access creation, after surgery to assess maturation, or later when there is low flow, difficult cannulation, arm swelling, prolonged bleeding, abnormal pressures, or clot concern.

    What the report may include

    A focused report can document access type, inflow artery, outflow vein, flow volume when feasible, depth, diameter, stenosis clues, thrombus, pseudoaneurysm, or surrounding fluid collection, depending on the clinical question.

    Coordinate with the dialysis team

    Bring dialysis-unit notes, access history, operation date, previous reports, and the specific problem noticed during dialysis. The ultrasound result should support the nephrology and vascular team plan.

    Important Signs to Mention

    Low access flow
    High venous pressure
    Difficult cannulation
    Arm swelling
    Prolonged bleeding
    Pre-operative vein mapping
