Evaluation of traumatic groin arteriovenous fistulas with duplex Doppler sonography.
Femoral arteriovenous fistula is a rare complication of percutaneous transfemoral catheterization. We report the duplex Doppler findings of three such cases. Continuous positive diastolic arterial flow, as well as an abnormal venous flow pattern, was observed in all cases. When present, these Doppler spectral changes support the diagnosis of arteriovenous fistula.
