Arteriovenous fistulas in the neck: diagnosis with color Doppler sonography
A. Lopez-Medina, I. Lopez-Vidaur, R. Villoria, G. Fernandez-Canton and J. I. Martin-Gomez
We report the use of color Doppler imaging in the diagnosis of four arteriovenous fistulas in the neck region: two had a traumatic origin and two were spontaneous. A perivascular color artifact was the most common initial finding on color images to indicate the underlying abnormality. In all four cases, a low-resistance flow with high systolic and diastolic velocities was observed in the feeding artery. Although angiography remains essential before therapeutic embolization, color Doppler sonography may be an important tool for screening and follow-up of cervical arteriovenous fistulas.
