Abstract
The four pulmonary veins carry oxygen-rich blood from the lungs to the left atrium of the heart. They are the only veins in the post-fetal human body that carry oxygenated blood. They commence in a capillary network upon the walls of the air sacs, and join together form one vessel for each lobule. These vessels unite successively and form a single trunk for each lobe (three for right and two for left lung). The vein from middle lobe of the right lung generally unites with that from the upper lobe, so that ultimately two trunks from each lung are formed. They open separately into the upper and back part of the left atrium. Occasionally, three veins on the right side remain separate, and not infrequently the two left pulmonary veins end by a common opening into the left atrium. The number of pulmonary veins opening into the left atrium can vary between three and five in the healthy population. Here we are discussing single anomalous pulmonary vein opening in the left atrium.
