Abstract Objective: To study the effect of MDCTA on the angle and distance of mesenteric artery and abdominal aorta in normal   and superior mesenteric artery syndrome and its effect on duodenal level. Materials and Methods: Using MDCTA, retrospective observation of 108 cases of normal and 17 cases of superior mesenteric artery syndrome in patients with superior mesenteric artery and abdominal aortic angle and duodenal level mesenteric artery and abdominal aortic space, and compared. Results: All MDCTA of patients with superior mesenteric artery syndrome showed 'clamp pressure' of the superior mesenteric artery and abdominal aorta in the duodenal segment, causing duodenal obstruction. Among the 108 normal subjects, the angle between the superior mesenteric artery and the abdominal aorta was 46.3 ° ± 16.5 ° and 14.3 ° ± 5.6 ° in the superior mesenteric artery syndrome. The normal level of the duodenum was superior to the superior mesenteric artery Arterial distance of 14.7 ± 4.4mm, superior mesenteric artery syndrome in patients with 4.5   ± 0.8mm, the two groups of data have significant statistical differences. Conclusion: MDCTA can show the duodenal obstruction caused by the mesenteric artery and the abdominal aorta of the superior mesenteric artery syndrome, and can accurately show the angle between the superior mesenteric artery and the abdominal aorta the reduction of distance, the diagnosis of superior mesenteric artery syndrome has important clinical value.
