What organs are supplied by the superior mesenteric artery and its branches?
What organs are supplied by the superior mesenteric artery and its branches?
The superior mesenteric artery provides blood to the pancreas and parts of the small intestine and large intestine. As a peripheral artery in the body’s circulatory system, it has several branches that send blood to various parts of the GI tract.
What is mesenteric artery bypass?
Mesenteric artery bypass is a surgical procedure that creates an alternate route (bypass) for blood to flow from the aorta (body’s largest artery) to the mesenteric artery (artery that supplies blood to the intestines).
How many branches of the superior mesenteric artery are there?
The SMA further divides into multiple jejunal and ileal branches. There are approximately 4 to 6 jejunal and 10 to 14 ileal arteries that originate from the left side of the SMA that run within the mesentery to form a series of arcades before reaching the intestinal wall.
What arteries come off the superior mesenteric artery?
The superior mesenteric artery then gives off several jejunal and ileal arteries to the left, and the middle colic, right colic, and ileocolic arteries to the right.
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 |
| Supplies | intestine |

What are the branches of the inferior mesenteric artery?
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 is mesenteric artery ischemia?
Mesenteric ischemia is decreased or blocked blood flow to your intestine. Ischemia means poor blood supply. The main arteries that carry blood and oxygen to your intestines are called the mesenteric arteries.
What is mesenteric artery stenosis?
Mesenteric artery stenosis is the narrowing of the arteries that supply blood to the intestines. These arteries are called the mesenteric arteries.
What are the branches of inferior mesenteric artery?
Which of the following is a branch of the superior mesenteric artery quizlet?
Inferior pancreaticoduodenal, intestinal, ileocolic, right colic and middle colic arteries. What are the five branches of the superior mesenteric artery? Left colic, sigmoid and superior rectal arteries.
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.
Which are branches of the inferior mesenteric artery quizlet?

- three branches of Inferior Mesenteric Artery. Left Colic Artery, Sigmoid Branches, Superior Rectal Artery.
- Left Colic Artery. supplies the end of transverse colon and beginning of descending colon.
- Sigmoid Branches.
- Superior Rectal Artery.
Is there a cure for the superior mesenteric artery syndrome?
Surgical Care. Another surgical approach to treating superior mesenteric artery syndrome is a duodenojejunostomy , in which the compressed portion of the duodenum is released and an anastomosis is created between the duodenum and jejunum anterior to the superior mesenteric artery. This is the classic approach to superior mesenteric artery syndrome.
What causes superior mesenteric artery (SMA) syndrome?
The syndrome is characterized by compression of the third portion of the duodenum due to narrowing of the space between the superior mesenteric artery and aorta and is primarily attributed to loss of the intervening mesenteric fat pad.
How is superior mesenteric artery syndrome diagnosed?
Diagnosis. Superior mesenteric artery syndrome is usually suspected based on signs and symptoms. A diagnosis can be confirmed by imaging studies such as an upper GI series (x-rays of the esophagus, stomach, and duodenum), hypotonic duodenography (an x-ray procedure that produces images of the duodenum), and computed tomography (CT scan).
What is the prevalence of superior mesenteric artery syndrome?
The superior mesenteric artery syndrome usually occurs in older children and adolescents . In one report, 75% of the cases occurred in patients aged 10-30 years.
