Neurogenic Thoracic Outlet Syndrome
Neurogenic thoracic outlet syndrome is an entrapment neuropathy involving the brachial plexus along its trajectory from the cervical spine to the axilla. Clinical presentation includes cervical and upper extremity pain as well as neurologic signs and symptoms in the lower trunk territory. Radiologic and electrophysiologic studies are helpful adjuncts in correctly identifying the site of compression. Initial management is usually conservative, with medication, physical therapy, nerve blocks, or botulinum toxin injection. Surgery often consists of brachial plexus neurolysis and removal of compression points through the supraclavicular approach. Good outcomes can be expected with careful patient selection, but available literature is of limited quality.
