PDF | Background: The topographic location of the superior mesenteric artery (SMA) and its branching pattern are usually arbitrary in textbooks. Mesenteric artery dissection is divided by location. The SMA is located anteriorly within the mesentery, at the junction of the small bowel mesentery and transverse mesocolon where it crosses over the duodenum. It originates from the aorta between the celiac artery and renal arteries. Ligation of the left colic artery will leave any remaining left colon and proximal anastomoses, reliant on the superior mesenteric artery (SMA) for collateral flow. Symptoms vary based on severity, but can be severely . Which of the following is done to expose the coeliac axis,left renal artery,superior mesenteric artery and abdominal aorta in a case of trauma? The main mesenteric arteries are the celiac artery, superior mesenteric artery and inferior mesenteric artery. It arises from the abdominal aorta, and supplies arterial blood to the organs of the midgut - which spans from the major duodenal papilla (of the duodenum) to the proximal 2/3 of the transverse colon. It is often seen in people who have hardening of the arteries in other parts of the body. It supplies the gut from the ampulla of Vater of the 2 nd part of the duodenum to the distal third of the transverse colon, and includes structures in between such as 5 : jejunum ileum appendix cecum ascending colon hepatic flexure proximal 2/3rd of the transverse colon The superior mesenteric artery arises off the anterior wall of the abdominal aorta about one centimeter inferior to the celiac trunk.

The superior mesenteric artery (SMA) is a major artery of the abdomen. BACKGROUND: Aneurysm of splenic artery (SA) which arises from the superior mesenteric artery (SMA) is a very rare condition. A watershed area exists between the SMA and the IMA at the splenic flexure of the colon, known as Griffiths' point [ 2 ]. It supplies blood to the midgut, i.e., the distal half of the duodenum, the jejunum, the ileum, the ascending colon, and the proximal half of the transverse colon. Superior mesenteric artery (SMA) syndrome is a rare condition that involves compression of the third portion of the duodenum which is the upper part of the small intestines just past the stomach. Background: Superior mesenteric artery (SMA) injuries are rare and devastating injuries incurring very high mortality rates. (Some labels may be used more than once.) Radiographic features Ultrasound Several values on doppler ultrasound have been proposed that include: The superior mesenteric glands receive lymph from the jejunum, ileum, cecum, vermiform process, and the ascending and transverse parts of the colon; lymph drains into the preaortic glands . Through the portal vein (which is formed by the splenic and superior mesenteric veins, behind the neck of the pancreas at L2) - liver - sinusoids - hepatic v. - inferior vena cava Superior mesenteric and inf. . Use of body casts. The superior mesenteric artery, which carries blood into the digestive system, is on the left side of the abdomen. Type Mesenteric v.: follows the . It is the purpose of this study to review our experience with these injuries, to analyze Fullen's classification based on anatomical zone and injury grade for its predictive value, and to correlate the American Association for the Surgery of Trauma-Organ Injury Scale . The SMV joins with the splenic vein and becomes the hepatic portal vein. 4,5 Tumours in the right colon derive blood supply from the SMA,6 while those in the left colon and rectum derive blood supply from the IMA. Anterior to the superior mesenteric artery lies the pylorus of the stomach, the neck of the pancreas, and the splenic vein.

Its does this through the following branches: left colic sigmoid branches superior rectal Superior mesenteric artery (SMA) syndrome arises from a reduction in the angle formed between the SMA and the aorta, thereby compressing the third portion of the duodenum. Definition duodenal compression secondary to a decrease in the angle between the superior mesenteric artery (SMA) and aorta Epidemiology Incidence ~ 0.01-0.8% in the US based on upper gastrointestinal tract barium studies Demographics more common in females 10-39 years of age Location the third portion of the duodenum becomes compressed Loss of tone in the abdominal wall. A mesenteric artery aneurysm is an aneurysm that occurs in either the inferior or superior mesenteric arteries that carry oxygen rich blood to the gastrointestinal tract (stomach, intestines, colon and rectum). The superior mesenteric artery (SMA) arises from the anterior surface of the abdominal aorta, just inferior to the origin of the celiac trunk, and supplies the intestine from the lower part of the duodenum through two-thirds of the transverse colon, as well as the pancreas. The superior mesenteric artery arises from the abdominal aorta at the level of the first lumbar vertebral body L1, approximately a centimeter below the coeliac trunk. The superior mesenteric artery travels behind the pancreas. This obstruction is often caused when the artery bends at an unnatural angle, compressing the duodenum against the heart's aorta. The arc of Riolan is an inconstantly situated artery, that courses medial to the mesenteric border of the colon, where it courses radially through the mid portion of the mesenteric arcade, near the inferior mesenteric vein. A major artery of the abdomen, the superior mesenteric artery (SMA) is a primary source of blood from the heart for many organs of the midgut, all of which are associated with the digestive system. 75726 59 (selective superior mesenteric artery angiogram) 36245 59 (first order cath placement) 99152 RENAL ANGIOGRAM/ INTERVENTION REPORT Procedure performed: SELECTIVE BILATERAL RENAL ARTERY ANGIOGRAM, INCLUDING SELECTIVE ANGIOGRAM OF RIGHT MAIN RENAL ARTERY, LEFT SUPERIOR RENAL ARTERY, AND SELECTIVE ANGIOGRAM OF LEFT INFERIOR RENAL ARTERY. | Find, read and cite all the research you . Mesenteric (or intestinal) artery disease is a condition that develops when the arteries in the abdomen that supply the intestines become narrowed, or blocked, by an accumulation of a fatty substance called plaque. superior mesenteric artery Abbreviation: SMA The second unpaired midline artery branching from the abdominal aorta; it originates 1 to 2 cm distal to the celiac artery. physical differences," such as differences in the length of a ligament that supports the duodenum or the angle and location of where the SMA branches from the AA. They eventually drain into superior and inferior mesenteric veins, then to hepatic portal vein. The often sudden onset of abdominal pain, usually, decreases in intensity to increase again afterward with the subsequent clinical deterioration associated to the peritonitis development [13]. All of these supply small intestine and proximal to mid colon. Spontaneous isolated superior mesenteric artery (SMA) dissection (SISMAD), in which the involvement of the aorta is ruled out, is considered to be an uncommon vascular disease with a potentially fatal pathology [1, 2]. As plaque builds up inside the artery walls, the arteries can become hardened and narrowed (a process called atherosclerosis). The superior mesenteric vein (SMV) is a large venous vessel located in the abdomen. The coeliac-superior mesenteric relationship was most consistent than between any other two points on the abdominal aorta; 85% of the SMAs were concentrated within a space of 1.00 cm (0.60-1.50 cm) from the CT. The celiac artery was engaged with a 5F Cobra-1 guide catheter and a 0.014 inch hydrophilic coronary wire was used to cross the lesion (Fig 1). The aim of this study was to present our experience with 2 such patients treated by coil embolization. Superior Mesenteric Artery Syndrome .

It is enveloped in fatty and lymphatic tissue and extends in a caudal direction at an acute angle into the mesentery. The superior mesenteric artery originates immediately below the celiac artery at the L1 vertebral body level (transpyloric plane), posterior to neck of pancreas and splenic vein.

At the S3 vertebral level, the artery divides into two terminal branches - one supplying each side of the rectum. The blood supply to the rectum arises from the superior, middle and inferior rectal arteries. Median Arcuate Ligament and Superior Mesenteric Artery Syndromes in a 28-Year-Old Man. Behind the neck of the pancreas, the superior mesenteric vein combines with the splenic vein to form the hepatic portal vein. It terminates by uniting with the splenic vein and forming the portal vein. The superior rectal artery is a continuation of the inferior mesenteric artery, supplying the rectum.
