Thoracic Outlet Syndrome Caused by Synostosis of the First and Second Thoracic Ribs: 2 Case Reports and Review of the Literature

We present 2 cases of combined arterial and neurogenic thoracic outlet syndrome triggered by trauma in patients with congenital synostoses of the first and second ribs. These patients were successfully treated with supraclavicular resection of the first and second ribs and scalenectomy. We review these cases and the associated literature on thoracic outlet syndrome and rib synostosis.
