[Vascular complications associated with cervical rib syndrome].

Two cases are reported of vascular complications in the cervical rib syndrome. In one case thrombosis developed in the distal part of the brachial artery, and in both cases compression of the subclavian artery could be demonstrated clinically and during arteriography. Attention is called to the necessity of surgical treatment of patients with evidence of vascular compression in view of the possibility of thrombotic complications. Coexistence of several causes of compression and the relationship of good therapeutic result to removal of all causes is stressed.
