Origin

The left inferior pulmonary vein is formed by the union of the superior and common basal veins.

Course

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

Tributaries

The superior and common basal veins are direct tributaries of the left inferior pulmonary vein.

Structures Drained

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