The cranial mesenteric vein (lat. vena mesenterica cranialis; synonyms: vena intestinalis cranialis, vena colica cranialis, superior colic vein) is a large vein that is located in the mesentery of the small intestine and collects blood from the small intestine, colon and rectosigmoid region. It is one of the main veins that participate in venous outflow from the abdominal cavity.
The cranial mesenteric vein begins at the junction of the colon and sigmoid colon and runs downward and medially, passing through the mesentery of the small and large intestines. It collects blood from all parts of the intestine and colon, as well as from the rectum and sigmoid colon. The cranial mesenteric vein has numerous branches and anastomoses that ensure the exchange of blood between various parts of the intestine and other venous systems of the body.
The importance of the mesenteric cranial vein is that it plays an important role in maintaining normal venous drainage from the abdominal cavity and intestines. Any disturbances in this system can lead to impaired venous circulation and the occurrence of various diseases, such as varicose veins, thrombosis and others.
To prevent problems with this important system, you need to monitor your health and lifestyle. It is recommended to undergo regular medical examinations and monitor your diet to maintain normal venous drainage. In addition, it is important to avoid excessive physical activity and stress, which can lead to overstrain of the venous system.
