Where is the superior mesenteric vein located?
abdomen
Location. The SMV is located on the right anatomical side of the abdomen and is part of the hepatic portal venous system. The superior mesenteric artery, which carries blood into the digestive system, is on the left side of the abdomen.
Where does the superior and inferior mesenteric vein drain into?
Splenic vein
The inferior mesenteric vein is a large venous trunk located in the abdomen. It is a continuation of the superior anorectal vein, also referred to as the superior rectal vein….Inferior mesenteric vein.

What does inferior mesenteric vein drain into?
Supply. The inferior mesenteric vein usually drains into the splenic vein; however, anatomical variants where it drains to the superior mesenteric vein or at the splenoportal angle are not uncommon.
What vein is SMV?
The superior mesenteric vein (SMV) is a major venous tributary of the abdominal cavity. Embryologically derived in association with the vitelline vein, the superior mesenteric vein lies lateral to the superior mesenteric artery (SMA) and serves to drain the vast majority of the organs of the abdominal cavity.
How superior mesenteric vein is formed?
Anatomical terminology The superior mesenteric vein is a blood vessel that drains blood from the small intestine (jejunum and ileum). Behind the neck of the pancreas, the superior mesenteric vein combines with the splenic vein to form the hepatic portal vein.
Does the superior mesenteric vein drain directly into inferior vena cava?
The hepatic portal vein (Figs 4.60, 4.61) is formed by the union of the superior mesenteric and the splenic veins behind the neck of the pancreas. Blood then traverses the liver in the hepatic sinusoids and empties into the central veins through which it reaches the inferior vena cava.
Is there a inferior mesenteric vein?
The inferior mesenteric vein (IMV) drains the descending colon, the sigmoid colon, and the rectum through the left colic vein, the sigmoid branches, and the superior rectal vein, respectively. The IMV joins the splenic vein, which then joins the SMV to form the portal vein.
How do you identify an inferior mesenteric vein?
Venous Anatomy The inferior mesenteric vein usually enters the splenic adjacent to the confluence, but it may also enter the SMV either at or just caudal to the confluence. The coronary vein most often drains into the cephalic aspect of the main portal vein just beyond the confluence of the SMV and splenic vein.
What is inferior vena cava?
The IVC is a large blood vessel responsible for transporting deoxygenated blood from the lower extremities and abdomen back to the right atrium of the heart. It has the largest diameter of the venous system and is a thin-walled vessel.
Where does SMV drain?
Where does the inferior mesenteric vein ( IMV ) end?
In human anatomy, the inferior mesenteric vein (IMV) is a blood vessel that drains blood from the large intestine. It usually terminates when reaching the splenic vein, which goes on to form the portal vein with the superior mesenteric vein (SMV).
Where does the inferior mesenteric vein cross the testicular artery?
Relations. The inferior mesenteric vein lies left of the inferior mesenteric artery and anterior to the left psoas major muscle, close to the ligament of Trietz. It can cross the left testicular artery or ascend medially to it.
What is thrombosis of the superior mesenteric vein?
The superior mesenteric vein combines with the splenic vein to form the portal vein. Thrombosis of the superior mesenteric vein is quite rare, but a significant cause of mesenteric ischemia and can be fatal. It is estimated that 10–15% of mesenteric ischemia is due to mesenteric thrombosis.
Where is the superior mesenteric artery located in the body?
Superior mesenteric artery. The superior mesenteric artery (Latin: arteria mesenterica superior) is a blood vessel that arises from the anterior surface of the abdominal aorta just below the origin of the coeliac trunk. It provides part of the intestines and pancreas with oxygenated blood.
Where is the superior mesenteric vein located? abdomen Location. The SMV is located on the right anatomical side of the abdomen and is part of the hepatic portal venous system. The superior mesenteric artery, which carries blood into the digestive system, is on the left side of the abdomen. Where does the superior and inferior…
