Description

The left lung is drained via the left superior and inferior pulmonary veins. The left superior pulmonary vein is formed by the union of the apicoposterior, anterior, and lingular veins, while the left inferior pulmonary vein is formed by the union of superior and common basal veins.

Both the left superior and inferior pulmonary veins travel medially, anterior to the descending thoracic aorta and pierce through the fibrous pericardium to reach the posterior aspect of the left atrium. The left pulmonary veins are separated from the right counterparts by the oblique pericardial sinus.
