Mesenteric vein
Mesenteric Vein
The Mesenteric Vein is a major blood vessel in the human digestive system. It is responsible for draining blood from the majority of the small intestine and portions of the large intestine. The mesenteric vein is divided into two main branches: the Superior Mesenteric Vein (SMV) and the Inferior Mesenteric Vein (IMV).
Anatomy[edit | edit source]
The SMV and IMV have different areas of drainage. The SMV drains the small intestine, the cecum, the ascending colon, and the transverse colon. The IMV drains the descending colon, the sigmoid colon, and the rectum.
The SMV runs a course that is somewhat parallel to the Superior Mesenteric Artery. It begins in the mesentery of the small intestine, where it is formed by the union of several smaller veins. The IMV, on the other hand, begins near the rectum, where it is also formed by the union of smaller veins.
Clinical Significance[edit | edit source]
The mesenteric vein is of clinical significance as it can be involved in several medical conditions. These include Mesenteric Ischemia, Mesenteric Vein Thrombosis, and Portal Hypertension. Understanding the anatomy and function of the mesenteric vein is crucial in the diagnosis and treatment of these conditions.
