Management of Thoracic Outlet Syndrome and Cervical Rib Removal & Scalenectomy
Young patients with Thoracic outlet Syndrome and cervical rib always presents with neurovascular symptoms and signs. The corner stone in management is Anterior scalenectomy and excision of the cervical rib from supra clavicular approach. The post stenotic dilatation from the compression of the thoracic outlet that is usually found in subclavian artery will correct itself over time
