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

Completed
Conditions
Thoracic Outlet Syndrome
Interventions
Diagnostic Test: Transcutaneous oximetry
Registration Number
NCT05702866
Lead Sponsor
University Hospital, Angers
Brief 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.

Primary Outcome Measures
NameTimeMethod
DROPmin according on the type of compressionthirty minutes

Variation in upper limb ischemia is estimated by TcpO2 measurement and calculating of the DROPmin (TcpO2 variation regarding a reference) depending on the type of damage (arterial, venous, or both arterial and venous).

DROP is Decrease Rest of Oxygen Pressure

Secondary Outcome Measures
NameTimeMethod
DROPmin according on the degree of arterial stenosisthirty minutes

To assess the correlation between the severity of upper limb ischemia by TcpO2 measurement and the degree of arterial stenosis observed in diagnostic arteriography.
