Twenty-one human tracheal specimens were perfused and dissected, 10 with conventional techniques and 11 with clearing and microdissection techniques. The lateral pedicles of the trachea and esophagus induct vessels from the inferior thyroid, subclavian, supreme intercostal, internal thoracic, innominate, and superior and middle bronchial arteries. These vessels are interconnected along the lateral surface of the trachea by an important longitudinal vascular anstomosis. From the 2 lateral longitudinal anastomoses the lateral and anterior tracheal walls receive their blood supply through transverse segmental vessels that run in the soft tissues between the cartilages. These transverse vessels interconnect the longitudinal anastomoses across the midline and feed the submucosal capillary network that arborizes richly beneath the endotracheal mucosa. The tracheal cartilages receive nourishment from the capillary bed applied to their internal surface. The esophageal arteries and their subdivisions that supply the posterior membranous wall of the trachea contribute almost nothing to the circulation of the cartilaginous walls.
