Thoracic outlet syndrome in children.

Abstract

Thoracic outlet syndrome, although uncommon in children, may be precipitated during rapid growth in adolescence, especially in association with a cervical rib. Four children exhibited the aching, tiredness in the limb, and occasional paresthesia in adolescence. Two had a cervical rib requiring removal, after which the symptoms disappeared. The other two were treated nonoperatively with shoulder-strengthening exercises and avoidance of posturing that elicited the symptoms. It is proposed that in a child, the anatomy of the thoracic outlet is constantly changing with growth and development of the structures that form the thoracic outlet, as well as those that traverse the outlet itself. A conservative approach to these symptoms is warranted in the first instance to allow further growth and remodeling of the thoracic outlet, which may be sufficient to accommodate the nerve roots and brachial plexus and alleviate the symptoms. Excision of the cervical rib in the presence of increasing and chronic symptoms can be quit beneficial.
