Summary

Thoracic outlet syndrome (TOS) is characterized by nervous, venous or arterial symptoms resulting from a compression of the thoracic bundle in the thoracic outlet. The diagnostic approach of TOS is still controversial. The investigating team is interested in arterial TOS and have already been able to demonstrate the presence of arm ischemia during dynamic maneuvers using transcutaneous oximetry (TcpO2). The correlation between the measurement of TcpO2 during dynamic maneuvers and the vascular compression type (arterial, venous or both) will be evaluated. The evaluation the correlation between TcpO2 and degree of arterial compression observed in dynamic arteriography (considered as a gold standard examination) will be calculated too. The use of TcpO2 could be developed in the diagnosis assessment of TOS.
