Facial artery pseudoaneurysm: diagnosis by colour Doppler ultrasonography.

Pseudoaneurysms of the facial region are rare and usually result from direct penetrating or blunt trauma. The authors report a pseudoaneurysm of the facial artery in a 22-year-old man injured in a motor vehicle accident. Colour Doppler ultrasonography was used to locate the aneurysm sac and establish its relation to the adjacent facial artery. Successful operative repair of the aneurysm was performed on the basis of the sonographic findings alone, without selective angiography.
