肠系膜上动脉分型与胡桃夹综合征关系的MSCT评价

Evaluate the Relation between Nutcracker Syndrome and Superior Mesenteric Artery Using MSCT

目的探讨肠系膜上动脉(SMA)形态与胡桃夹综合征之间的关系。资料与方法54例肾脏增强扫描患者按SMA形态(A型和B型)分成两组,测量SMA近段与远段的夹角和SMA与AA的夹角,并进行统计学分析。结果两型SMA与腹主动脉(AA)的夹角有统计学差异,同时B型SMA更易发生胡桃夹综合征。结论MSCT可以很好地评价SMA与胡桃夹综合征之间的关系。

Objective To explore the relationship between morphology of superior mesenteric artery and nutcracker syndrome.Materials and Methods 54 patients who were performed CT contrast enhancement were divided into two groups（Type A and Type B） according to morphology of superior mesenteric artery.The angle between proximal and distal segment of superior mesenteric artery and the angle between proximal segment of superior mesenteric artery and abdominal aorta were measured and analyzed.Results The angle between proximal segment of superior mesenteric artery and abdominal aorta in type B was smaller than that of in type A,which had statistic difference.The patients in type B showed higher possibility of nutcracker syndrome.Conclusion MSCT can correctly evaluate the relationship between morphology of superior mesenteric artery and nutcracker syndrome.
