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 The pulmonary arteries have been retracted downward.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
