Dissection of mediastinum and paravertebral structures
Superior mediastinum.
The lymphatic structures have been removed from along the trachea so that the cardiac and pulmonary nerves can be more readily visualized. Filaments of the cardiac plexus have been cut off and laid across the pulmonary artery in such a way that their various connections are more clearly visible. The pulmonary arteries have been retracted downward.
  1. Anterior scalene muscle
  2. Right subclavian artery
  3. Common carotid artery
  4. Right vagus nerve
  5. Middle cervical cardiac nerve (this filament can be traced upward between the arteries to a point where it joins the cervical sympathetic trunk above the stellate ganglion)
  6. Upper pointer: Inferior cardiac branch of vagus nerve Lower pointer: Bronchial branch vagus nerve
  7. Ascending aorta
  8. Cardiac plexus (deep portion)
  9. Pulmonary plexus
  10. Left pointer: Right main bronchus Right pointer: Tracheobronchial lymph node inferior
  11. Right pulmonary artery
  12. Cricoid cartilage
  13. Trachea
  14. Esophagus
  15. Recurrent laryngeal nerve
  16. Cervical nerve VII
  17. Stellate ganglion
  18. Cervical cardiac nerve
  19. Vertebral artery
  20. Inferior cervical cardiac nerve
  21. Left pointer: Left common carotid artery Right pointer: Subclavian artery
  22. Left vagus nerve
  23. Upper pointer: Recurrent laryngeal nerve Lower pointer: Ligamentum arteriosum
  24. Left main bronchus
  25. Filament of pulmonary plexus
