It then turns backward and passes from left to right behind the omental bursa and drains into the portal vein. Thus, it acts as collaterals between the portal veins and the systemic venous system of the lower esophagus (azygous vein). Esophageal and paraesophageal varices are supplied primarily by the left gastric vein (due to flow reversal) and typically drain into the azygos/hemiazygos venous system.[1]References{{Gray's}}1. ^Siegelman, E.: "Body MRI", page 47.
