Late thoracic outlet syndrome secondary to pseudarthrosis of the clavicle

Abstract

Successful resolution of a late thoracic outlet syndrome secondary to pseudarthrosis of the clavicle was accomplished by surgical resection of the pseudoarthrosis and mid 3 cm of the clavicle, following conservative therapy which did not alleviate the symptoms. The patient was a 28-year-old woman. Arteriography demonstrated the lesion. A shoulder dislocation preceded the thoracic outlet syndrome; a congenital pseudarthrosis may have been present.
