Axillary artery and brachial plexus injury secondary to blunt trauma.

Abstract

Rupture of the axillary artery in the absence of a fracture of dislocation is a rare traumatic event. An associated injury to the brachial plexus may accompany an axillary artery injury but has rarely been reported in the literature. We present the case of an elderly female, who fell onto an outstretched arm and sustained an axillary artery rupture, combined with a brachial plexus injury. The patient in this case did well post-operatively. The challenge in these cases is early recognition and diagnosis of a vascular injury. A significant mechanism of injury needs to alert the clinician to the possibility of such injuries and if suspected, early investigation and surgical exploration should be initiated to prevent limb ischemia. Subsequently, if the neurological symptoms do not improve, consideration must be given to the possibility of a nerve injury and early recognition and management to prevent long-term functional deficits.
