The authors present immediate and long-term results of treatment of 117 patients with superior thoracic outlet syndrome (STOS). There were different reasons for compression of neurovascular fascicle in outlet of the thorax. The costaclavicular syndrome was a reason in 48 patients, additional cervical ribs had 36 patients. Skalenus syndrome was noted in 26 cases, rudimentary cervical ribs or hypertrophy of cervical vertebrae C7 had 7 patients. Raynaud’s syndrome took place in 19 cases. The required volume of diagnostic procedures and surgical treatment of STOS were determined according to the cause of the syndrome. Differentiated approach to the different forms of STOS was used in relation to dominant symptoms of the disease and reasons for compression of neurovascular fascicle. This allowed getting positive results in majority of patients (90,4%) in long-term period.
