Abstract
We report a case of symptomatic axillary vein compression by the pectoralis minor muscle mimicking upper extremity thoracic outlet syndrome (TOS). The cause of obstruction was determined by clinical findings and dynamic venography. The patient underwent division of the pectoralis minor muscle with resolution of venographic findings and symptoms. Pectoralis minor compression of the axillary vein is a rare but described entity that needs careful review to reach the correct diagnosis and establish proper treatment.
