Giant pseudoaneurysm of subclavian artery after blunt chest trauma

Subclavian artery (SCA) pseudoaneurysm after blunt chest trauma is rare and its delayed presentation months after the SCA injury is even rarer. Herein we discuss a case of SCA pseudoaneurysm in a 74-year-old man who presented to us 5 months after blunt chest trauma. He had been managed conservatively for the fracture of first rib and clavicle until presentation to our hospital. He had uncontrolled hypertension and a rapidly increasing large painful swelling (10 by 8 cm) in left clavicular region along with purplish discoloration of the overlying skin. The diagnosis was confirmed after computed tomography angiography and the patient was successfully treated with surgical evacuation of clots, primary repair of the rent in the SCA, and plating of clavicular fracture.
