What are the branches of SMA?
SMA Branches
| Branch | Supplies |
|---|---|
| intestinal arteries | branches to ileum, branches to jejunum (proximal loop) |
| ileocolic artery | supplies last part of ileum, cecum, and appendix (distal loop) |
| right colic artery | to ascending colon (distal loop) |
| middle colic artery | to the transverse colon (distal loop) |
How do you remember the branches of the superior mesenteric artery?
There is a quick little way to remember all superior mesenteric artery branches to the large intestine. Just keep in mind ‘MRI’, which stands for: Middle colic a. Right colic a.
What is the SMA in anatomy?
The superior mesenteric artery (SMA) is one of the three non-paired major splanchnic arteries in the abdominal cavity arising from the abdominal aorta and supplying the midgut.
Which are branches of the superior mesenteric artery?
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.
What is the female gonadal artery?
The gonadal arteries are the paired primary vascular supply to the ovaries in the female and the testes in the male. As the anatomy of the gonadal arteries differs substantially between the sexes, they are covered separately: ovarian arteries.
Can SMA syndrome be cured?
SMAS is a medically treatable cause of small bowel obstruction with an overall good prognosis. Conservative medical treatment with nutritional rehabilitation is the least risky of treatment options and is successful in the majority of patients.
What is SMA surgery?
Options for surgery include a duodenojejunostomy or gastrojejunostomy to bypass the obstruction or a duodenal derotation procedure (otherwise known as the Strong procedure) to alter the aortomesenteric angle and place the third and fourth portions of the duodenum to the right of the superior mesenteric artery.
What are the 3 mesenteric arteries?

- Nitric Oxide.
- Renal Artery.
- Vasodilatation.
- Mesenteric Ischemia.

How would you know if you had an aneurysm in your stomach?
If you have an enlarging abdominal aortic aneurysm, you might notice: Deep, constant pain in the belly area or side of the belly (abdomen) Back pain. A pulse near the bellybutton.
Where are the branches of the SMA located?
SMA Branches. The middle, right, and ileocecal branches anastomose with each other to form a marginal artery along the inner border of the colon. This artery is completed by branches of the left colic which is a branch of the inferior mesenteric artery .
Which is larger the SMA or the superior mesenteric artery?
Frontal view of the superior mesenteric artery and its branches. The large vessel (blue) beside the SMA is the superior mesenteric vein.
What happens if the SMA is occlusioned?
Acute occlusion of the SMA almost invariably leads to intestinal ischemia and often has devastating consequences, with up to 80% of SMA occlusions leading to death. The SMA can compress the left renal vein, leading to nutcracker syndrome; and/or the third (horizontal) part of the duodenum, leading to superior mesenteric artery syndrome.
Which is part of the pancreas hooks around the SMA?
uncinate process of pancreas – this is a small part of the pancreas that hooks around the SMA. The SMA typically runs to the left of the similarly named vein, the superior mesenteric vein. After passing the neck of the pancreas it starts giving off its branches.
