The azygos vein transports deoxygenated blood from the posterior walls of the thorax and abdomen into the superior vena cava.. It is formed by the union of the ascending lumbar veins with the right subcostal veins at the level of the 12th thoracic vertebra, ascending to the right of the descending aorta and thoracic duct, passing behind the right crus of diaphragm, anterior to the vertebral ...
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 ...
Azygos lobe on chest X-ray. Arrowheads show the delineation of the lobe. Arrow points to the azygos vein. In human anatomy, an azygos lobe is a normal anatomical variation of the upper lobe of the right lung. [1] It is seen in 0.3% of the population. [2]
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.
the azygos vein (in the case of the right ascending lumbar vein). [1] [2] the hemiazygos vein (in the case of the left ascending lumbar vein). [1] The first and second lumbar veins ends in the ascending lumbar vein(the third and fourth lumbar veins open into the posterior aspect of the inferior vena cava)
Mintel, Fresh Thyme, Tastewise, and Whole Foods all point to the fact that the 2025 “health foods” will be rooted in functionality, meaning bites and sips that support gut health metabolism ...
Neurogenic TOS includes disorders produced by compression of components of the brachial plexus nerves. The neurogenic form of TOS accounts for 95% of all cases of TOS. [21] Arterial TOS is due to compression of the subclavian artery. [21] This is less than one percent of cases. [2] Venous TOS is due to compression of the subclavian vein. [21]
