Bilateral arterial thoracic outlet syndrome with intermittent subclavian artery occlusion

摘要

Etiologically, a significant percentage of patients with TOS presenting with vascular compressive symptoms of the upper extremity have congenital bony abnormalities. Cervical ribs occur in a small percentage of the general population and in a majority of cases, when seen is an incidental finding. Arterial TOS is a rare presentation that may result from the compression of the subclavian artery as it courses through the neck to the axilla. In this article we present a case of a young female with symptoms of vascular insufficiency resulting from fixed and dynamic subclavian artery narrowing and occlusion secondary to a congenital cervical rib.
