Reason: Evaluate fistula for abscess History: fever Images demonstrate a tubular structure within the superficial soft tissues of the left anterior arm which presumably represents a dialysis AV fistula. Color Doppler flow is present within the structure with some aliasing suggestive of turbulent flow. No abnormal fluid collections are identified within the adjacent surrounding soft tissues to suggest abscess.
1.No evidence of abscess associated with the left upper arm AV fistula. 2.Turbulent flow within the fistula. Dedicated vascular ultrasound can be considered as clinically warranted.
