Dissection of thorax from a posterior approach

Thoracic viscera.

The thoracic aorta and the azygos and hemiazygos veins have been removed to display the thoracic duct and the esophagus. Delicate connective tissue has been stripped from the esophageal wall. Numerous, small veins were present near the lower end of the esophagus, most of which have been cut away. The lungs are deflated.
