Review articleFirst Rib Resection in Thoracic Outlet Syndrome
Section snippets
Pathophysiology of TOS
Thoracic outlet syndrome results from impending thoracic outlet pressure on the neurovascular bundle exiting the thoracic cavity and entering the upper extremity. The pressure is created by several factors. These include the first rib and accessory or cervical ribs. Associated surrounding hypertrophic muscles, namely the scalene and the subclavius with their corresponding tendons, will also contribute to this local pressure syndrome. Detailed understanding of the local anatomy is critical in
Diagnosis
A detailed history and examination is usually sufficient to suspect and even diagnose TOS. Arm claudication, exercise-induced paresthesia, color discoloration after exercise or after erect postures are highly suspicious of TOS. Absent radial pulse with contralateral head rotations (Adson maneuver) is helpful but not always present in patients with TOS. Some normal individuals also tend to have a positive Adson test. Additional investigations are helpful but not mandatory in the diagnostic
Treatment
Physical therapy with special dedicated postural exercises should be routinely used as the initial treatment for TOS. However, patients with severe symptomatic TOS will often not benefit from physical therapy.1
The decompression of the neurovascular bundle in vascular TOS should include the first rib resection in each case.8 This is an essential step in therapy of all 3 types of TOS (neurogenic, venous, and arterial).

Discussion
Some prefer a combination of approaches to treat TOS. Vascular TOS is seen less frequently than the neurogenic form; however, in most cases it requires surgical treatment. Some prefer a combined supraclavicular and infraclavicular approach because it offers complete exposure of the subclavian artery, cervical and first ribs, and all soft tissue anomalies.22
One study followed 300 operations for TOS for at least 1 year. The first group was treated with either supraclavicular or transaxillary
Conclusions
Thoracic outlet syndrome should be suspected in individuals with upper extremity vascular compromise and paresthesia. First rib resection remains an important and essential step in management of the TOS. This procedure can be performed with minimal morbidity and with excellent outcomes. Both the supraclavicular route and the transaxillary route of the first rib resection remain effective surgical techniques and should be considered in patients with refractory symptoms.
