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 (celiac, superior, and inferior mesenteric).
1.      A double layer of peritoneum attached to the abdominal wall and enclosing in its fold a portion or all of one of the abdominal viscera, conveying to it its vessels and nerves.
2.      The fan-shaped fold of peritoneum encircling the greater part of the small intestines (jejunum and ileum) and attaching it to the posterior abdominal wall at the root of the mesentery (radix mesenterii). Syn: mesenterium dorsale commune, mesostenium. Syn: mesenterium [NA].
