Traumatic arteriovenous fistula.

Traumatic arteriovenous fistula in the head and neck may present a difficult problem in management. We present a surgical case of traumatic arteriovenous fistula between the right subclavian artery and internal jugular vein with false aneurysm formation. Traumatic injury of the subclavian artery causing arteriovenous fistula with false aneurysm is a serious surgical emergency with appreciable morbidity and mortality that requires early recognition and prompt surgical intervention.
