摘　　要：目的探讨西南人群中腹主动脉及其分支的正常参考值,为临床腹主动脉瘤的诊治提供依据。方法通过对20例尸体的腹主动脉及其分支进行长度、直径、血管间的夹角等测量。同时,选择4个城市人群共计300例无明显病变者行腹部CT血管造影(CTA),从影像学测量腹主动脉及分支的长度、直径、血管间的夹角等数据。结果腹主动脉显示率为100%,其平均长度为(12.96±0.81)cm,腹主动脉的直径在肾动脉平面(Ⅰ)、肠系膜下动脉平面(Ⅱ)及第4腰椎下缘平面(Ⅲ)的平均值分别为(1.93±0.28)cm、(1.55±0.23)cm、(1.61±0.19)cm;影像上平均值分别为(2.17±0.42)cm、(1.81±0.40)cm、(1.99±0.53)cm;髂总动脉的显示率为100%,左右髂总动脉间的夹角为(59.80±4.66)°,末端直径分别为(1.16±0.33)cm和(1.12±0.11)cm;腹腔干尸体显示率为100%,其平均长度是(1.61±0.27)cm,在尸体上的平均直径是(0.78±0.71)cm,影像上是(0.88±0.31)cm;肾动脉显示率为100%,左肾动脉平均长度为(2.58±0.50)cm,右侧为(4.26±0.65)cm,左侧肾动脉起始处的平均直径为(0.55±0.24)cm,右侧为(0.62±0.20)cm;肠系膜上动脉的显示率为100%,其在尸体上平均长度为(4.56±0.29)cm,影像测量值为(4.93±0.84)cm,与腹主动脉间夹角为(38.05±5.99)°;肠系膜下动脉的显示率为100%,在尸体上平均长度为(6.57±0.79)cm,影像测量值为(6.70±0.76)cm,与腹主动脉间夹角为(73.79±9.62)°,起始处直径为(0.48±0.29)cm。结论解剖和CTA显示了腹主动脉的脏支,测量了中国西南人群腹主动脉及其脏支的正常参考值,CTA对显示腹主动脉及其分支腔内、腔外和血管壁的病变有特殊的优势,可为患者术前提供血管的解剖数据。Objective To investigate the normal reference values of abdominal aorta and its branches in Southwest China,so as to provide basis for clinical diagnosis and treatment of abdominal aortic aneurysm.Methods The length,diameter and angle of the abdominal aorta and its branches were measured in 20 cadavers.At the same time,300 cases without obvious pathological changes in four urban populations were selected for abdominal CT angiography(CTA)to measure the length,diameter and angle of abdominal aorta and its branches.Results Display rate of abdominal aorta was 100%,the average length of abdominal aorta was(12.96±0.81)cm,the diameter of abdominal aorta was(1.93±0.28)cm,(1.55±0.23)cm,(1.61±0.19)cm in renal artery plane(Ⅰ),inferior mesenteric artery plane(Ⅱ)and lower edge plane of lumbar vertebrae(Ⅲ),and the average value on image was(2.17±0.42)cm,(1.81±0.40)cm,(1.99±0.53)cm;Display rate of common iliac artery was 100%,the angle between left and right common iliac artery was(59.80±4.66)°and the diameter of the end was(1.16±0.33)cm and(1.12±0.11)cm;Display rate of celiac trunk on cadaver was 100%,the average length was(1.61±0.27)cm,the average diameter on cadaver was(0.78±0.71)cm,the image was(0.88±0.31)cm;Display rate of renal artery was 100%,the average length of the left renal artery was(2.58±0.50)cm,that of the right was(4.26±0.65)cm,the initial average diameter of the left renal artery was(0.55±0.24)cm,and the right renal artery was(0.62±0.20)cm;Display rate of the superior mesenteric artery was(100%),that of the on cadaver was(4.56±0.29)cm,that of the image was(4.93±0.84)cm,and that of the angle between the abdominal aorta was(38.05±5.99)°;Display rate of the inferior mesenteric artery was(100%),the average length of the inferior mesenteric artery was(6.57±0.79)cm on the cadaver,the image was(6.70±0.76)cm,and that of the angle between the abdominal aorta was(73.79±9.62)°and the initial diameter was(0.48±0.29)cm.Conclusion The normal reference values of abdominal aorta and its viscera
