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 ...
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]

Azygos (impar), from the Greek άζυξ, refers to an anatomical structure that is unpaired. This is relatively unusual, as most elements of anatomy reflect bilateral symmetry. Azygos may refer to: Azygos anterior cerebral artery; Azygos artery of vagina; Azygos lobe; Azygos vein; Ganglion impar
The 3rd and 4th lumbar veins drain into the inferior vena cava. [3]The fate of the two superior lumbar veins is far more variable, and may drain into either the inferior vena cava, ascending lumbar vein, azygos vein, or (on the left side) the left renal vein; the 1st lumbar vein often passes inferiorly to join the 2nd lumbar vein, but may less commonly drain into the ascending lumbar vein, or ...
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)
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]
Posterior intercost veins that drain into the Superior intercostal vein - 2nd, 3rd, and 4th intercostal spaces. The superior intercostal vein then drains into the Azygous vein. Posterior intercost veins that drain directly into the Azygous vein - in spaces 5–11. Subcostal vein—below bottom (12th) rib and also drains into the Azygous vein.
