| mesenteric artery, inferior | The artery supplying nearly all the left half of the transverse colon, the whole of the descending colon, the sigmoid colon, and the greater part of the rectum. It is smaller than the superior mesenteric artery (mesenteric artery, superior) and arises from the aorta above its bifurcation into the common iliac arteries. (12 Dec 1998) |
|---|---|
| mesenteric artery occlusion | Obstruction of arterial flow in the mesenteric circulation by an embolus or thrombus; usually refers to occlusion of the superior mesenteric artery, although atherosclerotic narrowing may involve all three major splanchnic branches (coeliac, superior, and inferior mesenteric). (05 Mar 2000) |
| mesenteric artery, superior | A large vessel supplying the whole length of the small intestine except the superior part of the duodenum. It also supplies the caecum and the ascending part of the colon and about half the transverse part of the colon. It arises from the anterior surface of the aorta below the coeliac artery at the level of the first lumbar vertebra. (12 Dec 1998) |
| mesenteric cyst | A congenital thin-walled cyst of the abdomen between the leaves of the mesentery, which may be of wolffian or lymphatic duct origin. As it enlarges it may cause colicky pain and intestinal obstruction. (dorlamd, 27th ed) (12 Dec 1998) |
| mesenteric glands | See: mesenteric lymph nodes. (05 Mar 2000) |
| mesenteric hernia | Hernia through a hole in the mesentery. (05 Mar 2000) |
| mesenteric lymphadenitis | A condition clinically resembling acute appendicitis, in which there is inflammation of the mesenteric lymph nodes receiving lymph from the intestine. A septal form, which is frequently fatal, and a milder form, which is self-limited, are caused by yersinia (pasteurella) pseudotuberculosis. (12 Dec 1998) |
| mesenteric lymph nodes | Nodes located in the mesentery; they are of three classes: mesenteric lymph nodes, juxta-intestinal lymph nodes, and the superior middle group of mesenteric lymph nodes. Synonym: nodi lymphatici mesenterici. (05 Mar 2000) |
| mesenteric portion of small intestine | The freely movable portion of the small intestine supplied with a mesentery, comprising the jejunum and ileum. Synonym: mesenteric portion of small intestine. (05 Mar 2000) |
| mesenteric vascular occlusion | Obstruction of the flow in the mesenteric circulation by atherosclerosis, emboli or thrombi, stenosis, trauma, and compression or intrinsic pressure from adjacent tumours. Rare causes are drugs, intestinal parasites, and vascular immunoinflammatory diseases such as periarteritis nodosa and thromboangiitis obliterans. (12 Dec 1998) |
| mesenteric veins | Veins which return blood from the intestines; the inferior mesenteric vein empties into the splenic vein, the superior mesenteric vein joins the splenic vein to form the portal vein. (12 Dec 1998) |
| mesenteric vessels | <anatomy> Those arteries and veins that supply the small and large intestines. (27 Sep 1997) |
| middle group of mesenteric lymph nodes | The mesenteric lymph nodes located along the intestinal (jejunal and ileal) branches of the superior mesenteric artery. Synonym: nodi lymphatici superiores centrales, central mesenteric lymph nodes. (05 Mar 2000) |
| superior mesenteric artery | <anatomy, artery> Origin, abdominal aorta; branches, inferior pancreaticoduodenal, jejunal, ileal, ileocolic, appendicular, right colic, middle colic; anastomoses, superior pancreaticoduodenal and left colic. Synonym: arteria mesenterica superior. (05 Mar 2000) |
| superior mesenteric artery syndrome | <radiology> Partial obstruction of third part of duodenum by superior mesenteric artery seen with: marked weight loss, anorexia nervosa, total body casting X-ray: distension of proximal duodenum, classically disappears when prone (12 Dec 1998) |
