Thoracic outlet syndrome is an often misdiagnosed syndrome which consists of a neurovascular compression at the upper thoracic outlet. The clinical presentation can be variable, ranging from mild symptoms to venous thrombosis and muscle atrophy. Many aetiologies, both congenital and acquired, related either to bony or soft tissue anomalies, have been associated with this syndrome. As a consequence, the diagnosis is often challenging and sometimes it can be obtained only with surgical exploration. Additionally, no specific clinical test is considered diagnostic of thoracic outlet syndrome. However, the recent advances in imaging techniques together with a careful clinical evaluation give the surgeon the chance to recognize the constricting anatomy before surgery in many cases. No standard surgical procedure has been identified; however, in literature the largest series have been treated with transaxillary first rib resection. Here we report our experience in the surgical treatment of this syndrome with a minimum follow-up of three years. Our approach consists of performing a supraclavicular decompression without routine first rib resection. This allows for identifying and removing the constricting anatomy in most cases, with satisfactory results in 96.9% of patients and a low complication rate.

Subclavius posticus muscle is a supernumerary anatomical variation of the subclavius muscle. The aim of this study was to show the possible contribution of the posticus muscle in the development of unilateral thoracic outlet syndrome (TOS) in overhead athletes, presenting hypertrophy of the dominant arm due to their sport activity. Reported here are 2 young overhead athletes complaining pain, paresthesia, weakness in the dominant upper limb, although presenting none of the main shoulder and neurological disorders. After developing subclavian vein thrombosis, TOS was suspected and finally diagnosed by dynamic magnetic resonance angiography, which also showed bilateral subclavius posticus muscle in both patients. Despite bilateral subclavius posticus, TOS was only evident in the dominant limb in which the association of hypertrophy of lateral cervical muscles, resulting from the overhead sport activity, to the subclavius posticus likely led to a significant reduction of the upper thoracic outlet space.
