Thoracic outlet syndrome in the pediatric population: case series.

We present 4 patients, 4 months to 10 years of age, with thoracic outlet syndrome. All were referred to the brachial plexus clinic. Three patients were diagnosed with vascular thoracic outlet syndrome after clinical evaluation and diagnostic imaging. Three had a cervical rib and 1 had an anomalous first rib. All patients were treated surgically through a supraclavicular approach and had resolution of the symptoms. No postoperative complications were noted.
