摘要：

目的测量成人肠系膜上动脉（SMA）主干及邻近结构在多层螺旋CT（MSCT）上的正常数值范围，分析比较其年龄及性别之间差异。方法 260例检查者（男140例，女120例）行腹部MSCT增强扫描，采用薄层最大强度投影（MIP）图像后处理技术进行矢状位SMA血管成像，测量并分析SMA主干及邻近正常解剖结构。结果 SMA直径为（0.68±0.10）cm，SMA与腹腔干（CA）之间距离（1.55±0.33）cm ，SMA与肠系膜下动脉（IMA）之间距离为（6.69±0.88）cm ，SMA与腹主动脉（AA）间夹角为（59±18）° 。男女两组SMA、CA及AA直径差异均有统计学意义（P＜0.05），男女两组SMA与AA夹角、SMA 与IMA、SMA 与CA之间距离差异均无统计学意义（P＞0.05）。SMA、CA直径不同年龄组间差异无统计学意义（P＞0.05），AA直径不同年龄组间差异有统计学意义（P＜0.05）。结论 MSCT可清晰显示成人SMA主干及邻近结构解剖，并能准确测量其正常数值范围。

Abstract:

Objective To measure the caliber extent of superior mesenteric artery (SMA) stem and adjacent structures in different genders and ages. Methods The data from 260 patients (140 females, 120 males) were acquired. The caliber of SMA stem was measured and the adjacent anatomic structures were identified in patients who underwent abdominal contrast-enhanced multi-slice helical CT (MSCT). Sagittal imaging of SMA was acquired by thin slab maximum intensity projections(TSMIP) postprocessing technique. Results The diameter of SMA was（0.68±0.10）cm, the distance between SMA and celiac artery (CA) was (1.55±0.33）cm， the distance between SMA and inferior mesenteric artery (IMA) was（6.69±0.88）cm, and the angel between SMA and abdominal aorta (AA) was（59±18）°. The statistical difference between males and females was observed in the diameters of SMA, CA and AA（P＜0.05）. There was no statistical difference between males and females in the distances of SMA and CA, the distance of SMA and IMA, and the angel of SMA and AA（P＞0.05）. The diameter of CA had no significant difference（P＞0.05）, but there was statistical difference in the diameter of AA in different ages （P＜0.05）. Conclusion SMA stem and adjacent anatomical structures were delineated limpidly by MSCT and the extent of diameter could be measured exactly.
