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
