Delayed Subclavian Artery Aneurysm Following Fixation of a Clavicular Fracture.

Aneurysms of the subclavian artery are rare phenomena that have the potential for limb and life-threatening complications. Delayed diagnosis increases the risk of life-threatening complications or at the very least may result in a detrimental effect to both functional capacity and quality of life; primary care offers a vital opportunity to screen for such rare vascular complications and should be a consideration in all patients with evolving peripheral nerve or vascular symptoms with a history of localized clavicular trauma. We present the case of a left subclavian artery aneurysm with radial artery thrombotic sequelae following an injury and screw-plate fixation of his left clavicle. This required a 2-stage surgical approach to treatment and provides useful learning considerations for identifying rare vascular anomalies early in a primary care setting.
