Radial artery pseudoaneurysm complicating a Brescia-Cimino dialysis fistula

The authors describe an unusual case of radial artery pseudoaneurysm in a patient with a Brescia-Cimino fistula. Evaluation of a pulsatile mass on the patient's forearm which occurred after hemodialysis led to a nondiagnostic fistulogram. Color flow ultrasound was helpful in identifying the nature of the abnormality, which was subsequently confirmed arteriographically. This case illustrates that fistulography is not 100% sensitive and should be supplemented with other imaging modalities when the clinical and fistulographic findings are discordant.
