【摘要】：目的探讨肠系膜上动脉(SMA)与腹主动脉(AO)间隙面积对肠系膜上动脉综合征(SMAS)的诊断价值。方法收集接受腹部CT增强检查的24例SMAS患者(SMAS组)及42例非SMAS患者(非SMAS组),测量SMA-AO间隙面积、夹角、经十二指肠水平部中心SMA-AO距离及SMA起始部至十二指肠水平部中心水平距离,并进行统计学分析。结果两组SMA-AO间隙面积、夹角、经十二指肠水平部中心SMA-AO距离及SMA起始部至十二指肠水平部中心水平距离差异有统计学意义(P均0.05),ROC分析显示SMA-AO间隙面积、夹角、经十二指肠水平部中心SMA-AO距离及SMA起始部至十二指肠水平部中心水平距离的ROC曲线下面积分别为0.997、0.783、0.867及0.751。结论SMA-AO间隙面积对诊断SMAS具有较高的准确率,可作为诊断SMAS的参考标准。
[Abstract]:Objective to investigate the diagnostic value of the space area between superior mesenteric artery (SMA) and abdominal aorta (AO) in the diagnosis of superior mesenteric artery syndrome (SMAS). Methods 24 SMAS patients (SMAS group) and 42 non-SMAS patients (non-SMAS group) who received abdominal CT enhanced examination were collected. The area of SMA-AO space and the angle of SMA-AO space were measured. The distance of SMA-AO from the center of the horizontal duodenum and from the origin of SMA to the center of the horizontal part of the duodenum was analyzed statistically. Results there were significant differences between the two groups in SMA-AO space area, angle, SMA-AO distance from the center of the duodenum to the horizontal part of the duodenum and the distance from the beginning of SMA to the center of the horizontal part of the duodenum (P 0.05). ROC analysis showed that the area of the SMA-AO space, the angle of the interspace, the SMA-AO distance from the center of the duodenum through the horizontal part of the duodenum and the horizontal distance from the starting part of SMA to the center of the horizontal part of the duodenum were 0.9970.783c0.867 and 0.751respectively. Conclusion the space area of SMA-AO has a high accuracy in diagnosing SMAS, and it can be used as a reference standard for diagnosis of SMAS.
