Diagnosis and Treatment of Arterial Thoracic Outlet Syndrome in a Collegiate Volleyball Player: A Case Report

Abstract

A 19-year-old female volleyball player reported shoulder pain, numbness, tingling, and difficulty gripping in her left arm. Provocation tests were positive for thoracic outlet syndrome (TOS). Duplex ultrasonography revealed occlusion of the subclavian artery. The athlete underwent a first rib resection and scalenectomy. A cervical rib and 75% of the first rib were excised. Rehabilitation consisted of regaining range of motion and strength. Return to play occurred after 14 weeks of rehabilitation. Thoracic outlet syndrome is rare and often misdiagnosed. All sports medicine professionals should have an understanding of TOS symptoms and path to diagnosis.
