The Anterior Mediastinum

  • E. Robert Heitzman

Abstract

The anterior mediastinum is situated behind the sternum and in front of the great vessels and the pericardium. Its lateral margins are the mediastinal pleurae in contact with the anteromedial aspect of each lung (Figs. 5.1, 5.2, 5.8). Inferiorly, it reaches the diaphragm, while its upper limit is arbitrarily stated in most textbooks of anatomy as a line extending from the lower end of the manubrium of the sternum posteriorly to the inferior margin of the body of the fourth thoracic vertebra [18, 128]. For the purposes of this discussion, the anterior mediastinum can be considered to merge at its upper end with the thoracic inlet and to lie in front of the supra-azygos and infra-azygos areas on the right and the supra-aortic and infra-aortic areas on the left.
