The hilum of the spleen is an anatomical structure in the liver through which the hepatic veins and bile ducts pass. They are located on the bottom and upper surface of the gland. The hilum is known as the area of intersection of several hepatic structures, including blood vessels, bile ducts, and nerves.
The hilum of the spleen is considered an important clinical site because it controls blood circulation and metabolism in the liver. In the hilum area there are important elements such as the main hepatic vein (vein major), umbilical arteries, adjacent bile ducts and bundle veins. The main elements that control the functioning of the liver and blood pass through them. If any of the elements fails, other structures may begin to suffer from a lack of blood or oxygen.
Although the hilum of the spleen has many important functions, the exact location and appearance may vary depending on factors such as the individual's anatomy and the location of the liver.
