[Venous involvement in the thoracic outlet syndrome (apropos of 30 cases)].

This paper present 30 patients with subclavian venous compression caused by a thoracic outlet syndrome. 3 stages are differentiated: intermittent compression: 15 patients; acute occlusion: 5 patients; chronic occlusion: 10 patients. Every stage corresponds with a clinic and radiologic unit: venous claudication of the upper limb; phlebitis; post-phlebitis syndrome. 8/30 patients had a bilateral compression. 22/30 patients had an associated arterial compression. The hypertrophy of the subclavian muscle is the main etiology of the venous compression. The venography dynamic of the upper limb is the basic investigation. The resection of the first rib is the basic intervention, according to the technic of Roos. A venous thrombectomy was associated in 4 cases. A previous general thrombolysis was associated in one case.
