are diagnostic signs (4).
Superior mesenteric artery
syndrome may present acutely or chronically.
CT angiography of abdomen revealed significant reduction of the angle between aorta and superior mesenteric artery

Diagnostic criteria for mesenteric vascular spasm are proximal stenosis of the superior mesenteric artery
and main branch, abnormal images of mesenteric branches, arcade spasm of the mesenteric artery
, and poor contrast on internal images of the blood vessels in the mesenteric wall.

Firstly, the classic type is defined as malposition of bowel due to clockwise rotation of the small bowel and ascending colon, around the superior mesenteric artery
without evidence of any anomaly predisposing to the rotation .
Where, PA (Pulmonary artery), DA (Dorsal artery); MA (Mesenteric artery
) and IA (Iliac artery).
Two trunks arose separately from a very short CMT: 1) the gastro-splenic trunk divided into the left gastric artery and the splenic artery; and 2) the hepatomesenteric trunk divided into the common hepatic artery and the superior mesenteric artery
In 1928, Adachi described six types of divisions of the celiac trunk and superior mesenteric artery
(SMA) based on 252 dissections of Japanese cadavers (2).
