Vena hollow Ascending

The renal vein is one of the elements of the human circulatory system that connects the liver, gallbladder and spleen on the right side of the body. This vessel is about 8 centimeters long and has a diameter of about 2 mm. The name "renal vein" comes from the fact that it collects blood from the liver, kidneys and gallbladder.

The renal vein begins in the abdominal cavity, where it is formed from the confluence of the superior and inferior veins of the kidneys. It then moves towards the lumbar region, crosses the diaphragm and enters the right atrium. The renal vein is the main drainage route for blood from the kidneys, liver and gallbladder, which are supplied by this vein.

In addition to its connection to the liver, gallbladder and spleen, the renal vein also supplies higher organs such as the ureter and bladder. This allows the body to excrete urine and other fluids.

If there is an obstruction in venous drainage, such as a blood clot or other formation, the renal veins may become dilated and filled with blood and cause the development of chronic renal failure. Venous clinical diagnosis involves the use of contrast angiography, as well as other types of imaging.
