Study Notes
Contents of the Middle Mediastinum
- Arteries: thoracic aorta, manifold branches
- Veins: azygos, hemiazygos, and accessory hemiazygos venous system
- Nerves: forming the oesophageal plexus, autonomic sympathetic trunks, and the glanchnic nerves
- Tubes: oesophagus, thenar ducting is tight sido
- Lymph nodes: posterior mediastinal lymph nodes
Mediastinal Syndrome
- A clinical condition caused by compression of the contents of the superior mediastinum
- Caused by a space-occupying lesion (e.g. tumours, enlarged lymph nodes, or an orthotopic thyroid gland)
- Manifestations depend on the structures compressed
- Vessels: compression leads to venous congestion on the upper limb, hand, and neck
- Trachea or oesophagus compression leads to dyspnoea or dysphagia, respectively
- Nerves: compression of the left recurrent laryngeal nerve leads to hoarseness of voice
