Diagnostic Considerations

Differential diagnosis of arteriovenous fistula (AVF) includes other conditions that may cause hyperdynamic circulation (increased heart rate, increased cardiac output, and low peripheral resistance). Cirrhosis, hyperthyroidism, Paget disease of the bone, and, occasionally, vary large highly vascular tumors like sarcomas should be considered.

Missing the presence of AVF after blunt or penetrating trauma is easy, but this condition should always be looked for in this setting. In cases of any gunshot wound or stab wound that traverses the course of a blood vessel, ruling out vascular injury, particularly AVF, with an imaging study (duplex ultrasonography, computed tomography, magnetic resonance angiography, or even conventional angiography) is important. Failure to diagnose may have medicolegal implications.
