Thoracic outlet syndrome (TOS) is a complex neurovascular compression disorder. Surgical intervention offers satisfactory outcomes for selected patients with vascular or neurogenic TOS unresponsive to conservative treatment.

Area of Science:

  • Neurology
  • Vascular Surgery
  • Anatomy

Background:

  • Thoracic outlet syndrome (TOS) is a controversial and challenging clinical entity.
  • It encompasses neurogenic, vascular, and disputed types of TOS, often caused by neurovascular compression in specific anatomical spaces.
  • Symptoms include arterial insufficiency, venous obstruction, hand muscle wasting, paresthesia, and pain.

Purpose of the Study:

  • To provide a comprehensive review of thoracic outlet syndrome.
  • To cover its clinical presentations, surgical anatomy, diagnostic methods, treatment options, and outcomes.

Main Methods:

  • Review of TOS as a spectrum of disorders involving brachial plexus or subclavian vessel compression.
  • Diagnostic tools include detailed history, physical examination, electromyography, nerve conduction studies, and imaging.

  • Treatment involves conservative measures (exercise, physical therapy) followed by surgical options like supraclavicular or transaxillary approaches with first rib resection if conservative management fails.

    • Main Results:

    • TOS presents with diverse neurovascular symptoms due to compression in anatomical spaces like the interscalene triangle.
    • Accurate diagnosis relies heavily on clinical evaluation, supported by electrodiagnostic and imaging studies.
    • Surgical approaches include supraclavicular, transaxillary, and subscapular methods, often involving first rib resection.

    Conclusions:

    • Thoracic outlet syndrome is a difficult entrapment neuropathy.
    • Surgery is indicated for vascular and true neurogenic TOS, and for some cases of common/nonspecific TOS refractory to nonoperative treatment.
    • Careful patient selection is crucial for achieving satisfactory surgical outcomes.
