[Primary axillary subclavian venous thrombosis].

The thoracic outlet syndrome includes primary axillary-subclavian vein thrombosis. The subclavian vein is compressed in a narrowed costo-clavicular space during certain movements of the arm. The intermittent compression of the vein results in position-dependent symptoms often misinterpreted. When occlusion of the vein occurs, the diagnosis of deep venous thrombosis suffers no difficulty. Non invasive vascular diagnostic techniques are nowadays paramount. Treatment, medical and/or surgical (removal of the first rib), depends on the venous state of the upper extremity.
