    Abstract:
    BACKGROUND: Thoracic Outlet Syndrome (TOS) refers to compression of the neurovascular structures in the region between the scalene muscles and the first rib, or by anatomical abnormalities such as cervical rib, fibrous bands and other variations in the scalene musculature. METHODS: Our experience with 63 consecutive operations for TOS, over a period of 10 years, has been reviewed. Preoperative symptoms and signs, investigations, surgery done, complications and the outcome of surgery are analysed. RESULTS: A total of 60 patients underwent 63 operations for decompression of TOS. All the 63 first ribs, were excised by the transaxillary approach. In seven patients (16%), a combined transaxillary and supraclavicular approach was used. There was no operative mortality in this series. The operative complications included pneumothorax in four patients (6.3%), which was treated by insertion of chest drain, and lower brachial plexus neuropraxia in two patients (3%), which improved with conservative management. The mean duration of postoperative hospital stay was 3.6 days. At 12 months following surgery, 56 patients (93%) had complete or partial relief of symptoms and only four patients (6.6%) had no relief of symptoms. CONCLUSION: The results of the present study confirm that transaxillary excision of the first rib is a surgical procedure associated with very low morbidity and excellent relief of symptoms. It can therefore be offered as an early option for patients with thoracic outlet syndrome. It may be combined with the supraclavicular approach if exposure of the subclavian artery is required for vascular reconstruction.
