What is SMV medical abbreviation for?
The superior mesenteric vein (SMV) is a large blood vessel in the abdomen. Its function is to drain blood from the small intestine as well as the first sections of the large intestine and other digestive organs.
What is branch of SMA?
The distal branches of the superior mesenteric artery (right colic, ileocolic, and middle colic) and the inferior mesenteric artery (sigmoid and left colic) supply the colon. They are also connected to each other by an intricate arterial arcade along the mesenteric border known as the Marginal Artery of Drummond.
Where does SMV drain?
The SMV drains the small intestine, cecum, and ascending and transverse colon via the jejunal, ileal, ileocolic, right colic, and middle colic veins. The IMV drains the descending colon through the left colic, the sigmoid through the sigmoid vein, and the rectum through the superior rectal vein.
Where does superior mesenteric artery branch from?
The superior mesenteric artery provides oxygenated blood and nutrients to the intestines. These organs are part of the digestive system. The artery branches off of the aorta, which is the body’s largest blood vessel. Superior refers to the artery’s location above other arteries that supply the intestines.
What is SMV thrombosis?
Superior Mesenteric Vein (SMV) thrombosis is a rare disease entity that can result in life-threatening complications including hemorrhagic shock or intestinal infarction, but if discovered early, is treatable and potentially reversible.
What is SMA and SMV?
The smaller superior mesenteric vein (SMV) sign is a well‐known computed tomography (CT) parameter for acute superior mesenteric artery (SMA) occlusion. This CT sign is potentially beneficial for the early diagnosis of acute SMA occlusion; however, few reports have documented this sign.
What are the 5 main branches of the superior mesenteric artery?
|Superior mesenteric artery|
|Branches||inferior pancreaticoduodenal middle colic right colic intestinal branches (jejunal, ileal) ileocolic|
|Vein||superior mesenteric vein|
What causes SMV thrombosis?
Causes of Mesenteric Venous Thrombosis genetic disorders that make your blood more prone to clotting, such as Factor V Leiden thrombophilia, which is an inherited clotting disorder. abdominal infections, such as appendicitis. inflammatory bowel diseases, such as diverticulitis, ulcerative colitis, and Crohn’s disease.
What level is the IMA?
In human anatomy, the inferior mesenteric artery, often abbreviated as IMA, is the third main branch of the abdominal aorta and arises at the level of L3, supplying the large intestine from the distal transverse colon to the upper part of the anal canal.
What are the branches of IMA?
The branches of the inferior mesenteric artery include 1) the left colic, which is located retroperitoneally and supplies the descending colon; 2) the sigmoid branches, which supply the sigmoid colon; and 3) the superior rectal artery, which is the terminal branch of the inferior mesenteric artery at the pelvic brim.
What are the two portal systems?
circulatory system Lower vertebrates have two so-called portal systems, areas of the venous system that begin in capillaries in tissues and join to form veins, which divide to produce another capillary network en route to the heart. They are called the hepatic (liver) and renal (kidneys) portal systems.
How many types of portal system are there?
Lower vertebrates have two so-called portal systems, areas of the venous system that begin in capillaries in tissues and join to form veins, which divide to produce another capillary network en route to the heart. They are called the hepatic (liver) and renal (kidneys) portal systems.
What does it mean if the SMV is on the right?
The SMV is accompanied by the SMA and normally lies to the right. If it is not in this position, it can indicate intestinal malrotation. Relations anterior: neck of pancreas posterior: uncinate process of pancreas Tributaries mesenteric venous arcades (jejunal and ileal veins)
What are the branches of the SMA?
SMA Branches Branch Supplies inferior pancreaticoduodenal artery head of the pancreas and to the ascendin intestinal arteries branches to ileum, branches to jejunum ( ileocolic artery supplies last part of ileum, cecum, and right colic artery to ascending colon (distal loop)
What does SMVT stand for?
Isolated Superior Mesenteric Venous Thrombosis Isolated superior mesenteric venous thrombosis (SMVT) is when a blood clot forms in the SMV. It is a rare condition.
Is SMVT a rare condition?
It is a rare condition. SMVT can occur as a result of cancer, peritonitis, increased blood clotting (hypercoagulable state), protein C deficiency, polycythemia vera, recent abdominal surgery, high blood pressure in the portal vein ( portal hypertension ), or sepsis .
