Abstract
A total of 107 patients with thoracic outlet syndrome were reviewed an average of 4.1 years (range 2–11 years) after primary scalenotomy. The sample included 86 women and 21 men, and the mean age at surgery was 41.9 years (range 16–59 years). The three most disturbing pre-operative symptoms were pain at rest (87%), numbness (66%) and lack of power (55%). The post-operative success rate diminished from 71% 1 month after operation to 63% at follow-up. The retirement frequency increased from 6% up to 33% during the follow-up time. It was highest among factory workers at 60%. Of the patients older than 45 years at surgery, 68% were retired at follow-up. The importance of careful selection for operation is emphasized, and also the need to consider vocational rehabilitation before resorting to surgical treatment of thoracic outlet syndrome. We recommend surgical treatment for this disabling disorder, especially for younger patients with clear evidence of thoracic outlet syndrome who are engaged in occupations demanding little repetitive work. The best results have occurred in this group.
