The Common Vein Copyright 2008
Principles
Structure
Single common vein during embryology (4th week gestation) incorporated into the left dorsal atrium with 70% of patients having 4 pulmonary veins left superior (LS) left inferior (LI) right superior (RS) and right inferior (RI) which usually accommodates the middle lobe vein). The myocardium of the left atrium extends over the pulmonary vein for 1-2cms.
Congenital anomalies occur when there is over incorporation or under incorporation

Shape
Left pulmonary veins are oval ostia oval
Right pulmonary vein ostia are circular
Position
Usually right middle lobe vein drains into right superior vein in 70% directly into LA 20% and 5% intp RIPV
Lingula vein usually arises from the left superior pulmonary vein.
In 10-25% patients there is a single vein on one side. This is more common on the left
The specimen of heart and lungs is examined from posteriorly with the left atrium and 4 pulmonary veins. (overlaid in pearl white) The trachea and bronchi are intact (green). The left atrium lies just below in the angle of the carina.

This normal anatomic specimen from a posterior aspect showing the LPA (1) and upper lobe pulmonary veins (2) and lower lobe pulmonary veins (3) shows the left pulmonary veins (1) and left pulmonary artery. The two veins to one artery is the usual. Venous inflow must of course equal arterial outflow and so each vein carries about half the load and are about half the size of the main branch pulmonary artery

Anatomy of the Left Atrium |
The arteries and airways pair up and travel together down the respiratory tree branching in exactly the same way until they reach the pulmonary lobule. The pulmonary lobule, also called the secondary lobule is a structural unit surrounded by a membrane of connective tissue, and it is smaller than a subsegment of lung but larger than an acinus. This diagram shows two secondary lobules lying side by side. The pulmonary arteriole (royal blue) and bronchiole (teal) are shown together in the centre of the lobule (“centrilobular”), with two other pairs of bronchovascular bundles, while the oxygenated pulmonary venules (red) and lymphatics (yellow) are peripheral and also form formidable and almost inseparable pairs.
