Arterial complications of the thoracic outlet syndrome.
OBJECTIVE
Arterial complications due to compression of the thoracic outlet are uncommon. The objective of this study was to review our fairly extensive experience with this problem with particular reference to its management.


METHODS
Patients entered into the Vascular Clinic database were reviewed over an 11 year period. Twenty six records were found. In 24 patients the vasculopathy was caused by a cervical rib (complete in 15) and in two by an anomaly of the first rib. In all patients the basic arteriopathy was a fibrous structure with a post-stenotic aneurysm in 13. Seventeen presented with a fixed pulse deficit; 13 had a palpable aneurysm and 12 had distal embolisation.


RESULTS
Two patients refused operation. In 22 with cervical rib, the rib was removed via a supraclavicular incision, an anterior scalenectomy was performed and the arterial pathology repaired on its merit, usually by vein graft replacement or bypass. In two with first rib anomalies these were resected by the transaxillary route. Twenty three patients have been followed for between 3 months and 10 years; 20 are cured and three have residual claudication.


CONCLUSIONS
Our results show that simple excision of the cervical rib via the supraclavicular route together with vascular reconstruction is adequate. This is in disagreement with the view of those who advocate routine excision of the first rib in addition to cervical rib excision.
