Thoracic Outlet Syndrome Secondary to Vascular Insufficiency from Congenital Pseudarthrosis of the Clavicle: A Case Report.

CASE: An 18-year-old woman with a history of congenital pseudarthrosis of the clavicle (CPC) presented with episodes of right upper extremity ischemia. Vascular studies demonstrated an extensive thrombus with complete occlusion of the brachial artery. She underwent urgent thrombectomy. Subsequently, she underwent first rib resection and scalenectomy as well as pseudarthrosis takedown and fixation. Postoperatively, she returned to Division I collegiate soccer with complete symptomatic resolution.

CONCLUSION: We report a case of arterial thoracic outlet syndrome secondary to CPC.
