The "arch of the azygos vein" (arcus venae azygos) is an important anatomic landmark. As an anatomical variation in 1–2% of the population, the arch can be displaced laterally, thereby creating a pleural septum separating an azygos lobe from the upper lobe of the right lung. The origin and anatomical course of the azygos vein are quite variable.
Splenic vein thrombosis is a rare condition that causes esophageal varices without a raised portal pressure. Splenectomy can cure the variceal bleeding due to splenic vein thrombosis. [citation needed] Varices can also form in other areas of the body, including the stomach (gastric varices), duodenum (duodenal varices), and rectum (rectal ...
The esophageal veins drain blood from the esophagus to the azygos vein, in the thorax, and to the inferior thyroid vein in the neck. It also drains, although with less significance, to the hemiazygos vein, posterior intercostal vein and bronchial veins. [citation needed] In the abdomen, some drain to the left gastric vein which drains into the ...
A portacaval anastomosis or portocaval anastomosis is a specific type of circulatory anastomosis that occurs between the veins of the portal circulation and the vena cava, thus forming one of the principal types of portasystemic anastomosis or portosystemic anastomosis, as it connects the portal circulation to the systemic circulation, providing an alternative pathway for the blood.
It is a large-diameter (24 mm) short length vein that receives venous return from the upper half of the body, above the diaphragm. Venous return from the lower half, below the diaphragm, flows through the inferior vena cava. The SVC is located in the anterior right superior mediastinum. [1]
A vein disorder is a class of disease involving veins of the circulatory system. [1] Common vein disorders include: [citation needed] Varicose veins; Deep vein thrombosis; Superficial thrombophlebitis

The aorta is situated on the left, the thoracic duct in the middle, and the azygos vein on the right. [1]: 185 The hemiazygos vein may pass through the aortic hiatus [2] or may pass through the diaphragm independently through its own foramen in the left crus.
