Venography in axillary-subclavian vein thrombosis.

Nineteen patients with 20 axillary-subclavian vein thromboses were examined by venography. In 70% the axillary and subclavian veins were involved in continuity. The innominate vein was seldom involved, although demonstration of this was difficult. In 50% of the patients the thrombosis was a secondary phenomenon associated with either breast carcinoma, central venous pressure lines, heroin addiction, or cervical rib.
