The authors describe their experience with surgery of suspected TOS (8 cases) and traumatic TOS after clavicular fracture (1 case) in the last 2 years. In the group there were 7 women and 2 men aged 39-59 years with a history from 6 months to 26 years. Seven patients reported complete or almost complete relief of symptoms. In one case we observed progressive deterioration during 6 weeks postoperatively. All patients underwent decompression of the brachial plexus and subclavian artery from a supraclavicular approach. There was one case of reoperation after 15 years after primary surgery.
