Origin

The left superior pulmonary vein is formed in the parenchyma of the superior lobe of the left lung.

Course

As the left superior pulmonary vein exits the hilum of the left lung, it sits anterior to left main bronchus and anteroinferior to the left pulmonary artery. As it travels medially, the left superior pulmonary vein crosses anterior to the descending thoracic aorta, pierces the fibrous pericardium, and drains into the posterosuperior aspect of the left atrium.

Tributaries

The anterior, apicoposterior, and lingular veins unite to form the left superior pulmonary vein.

Structures Drained

The left superior pulmonary vein is responsible for the venous drainage of oxygenated blood from the superior lobe of the left lung.
