肠系膜上动脉的CT解剖及临床意义

CT anatomy of SMA and its clinical application

目的:通过对200例正常人及78例胰腺疾病的肠系膜上动脉(SMA)CT表现进行分析,揭示SMA诊断胰腺疾病的意义。方法:在CT片上对SMA直径及位置进行测量。结果:SMA正常位置不超过椎体左缘,SMA直径增粗和SMA周围脂肪层消失是诊断胰腺疾病的可靠依据。结论:SMA在胰腺疾病诊断中具有重要意义,可以大大提高其确诊率。

Objective:To study the effect of SMA in the diagnosis of pancreatic diseases by analysing expression of SMA (the superior mesenteric artery) in 200 CT normal examination and 78 pancreatic diseases . Methods: To measure diameter and location of SMA in CT plain film . Results: Abnormal position of SMA was not beyond the left margin of the adjacent vertebral body . Enlargement of SMA diameter and dispearance of SMA peripheral fat were reliable evidence for diagnosing pancreatic deseases . Conclusion: SMA has an important value in diagnosing pancreatic deseases,which greatly raises diagnosing efficiency .
