Vascular Compression Assessment Using Transcutaneous Oxymetry in Patients Suspected of Having Thoracic Outlet Syndrome

Apport de l'évaluation de l'ischémie de Membre supérieur Par oxymétrie transcutanée Dans la caractérisation de la Compression Vasculaire Chez Les Patients Suspects de Syndrome du défilé Thoraco-brachial

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.

Inclusion Criteria:

• patient suspected of having a thoracic outlet syndrome
• patient having carried out additional examinations as part of the diagnostic assessment : venous and arterial Doppler or dynamic arteriography and venography
• patient having carried out a dynamic TcpO2 recording

Exclusion Criteria:

• patient under 18 year old
• non french speaker
• patient who expressed his/her refusal
