Venous Vein

The cystic vein (lat. vena cystica) is a tubular blood vessel connecting the splenic vein and the left gastric vein with the umbilical vein. Its main function is to drain blood from the left ventricle and spleen into the superior vena cava.

Anatomically, the cystic vein is located between the greater curvature of the stomach and the left lobe of the liver. In the center between the top of the duodenum and the lower surface of the angle of the transverse colon. It passes through the back wall of the stomach, towards its anterior surface. Under the greater omentum, at the angle of the duodenum, the esophagus passes and the vein becomes deeper before entering the hepatoduodenal ligament and through it connecting to the umbilical vein.

The cystic vein has a segmental structure. It is divided into two main parts: 1. Upper part. It includes an expanded segment of the venous vessel located under the lesser curvature and gives off several lateral branches; 2. Bottom part. It is located below the level of the connection with the umbilical vein and supplies the diaphragm and renal veins. The segmental branches of the upper part of the cystic vein supply blood to the posterior parts of the pancreas, the posterior wall of the abdominal
