摘　　要：目的:探讨16层螺旋CT在诊断左肾静脉压迫综合征的应用价值。方法:回顾性分析43例经临床诊断为左肾静脉压迫综合征的患者(病变组)与50例正常肾血管者(对照组)的16层螺旋CT影像学资料,测量肠系膜上动脉(superior mesenteric artery,SMA)与腹主动脉(abdominal aorta,AA)的夹角(a)、左肾静脉(left renal vein,LRV)夹角受压处的截面积(s1)及近肾端LRV最宽处的截面积(s2),并计算s2/s1的比值(q)进行统计学分析。结果:病变组SMA与AA的夹角明显变小,两组比较a、s1、s2、s2/s1差异有统计学意义。结论:16层螺旋CT检查能清晰显示LRV的形态、测量各数值,评估LRV的受压变窄程度,对临床诊断、治疗具有重要的应用价值。Objective：To study the diagnostic value of 16-slices Spiral CT for left renal vein entrapment syndrome. Methods： Retro- spectively analyze the 16-slice spiral CT imaging data of 43 patients with a clinical diagnosis of left renal vein entrapment syndrome （disease group） and 50 patients with normal renal vascular（ control group） in order to measure the superior mesenteric artery（SMA） of the LRV angle compression at the cross-sectional area（ sl ） and near the renal end LRV widest cross-sectional area（s2）. Calculate the ratio of the s2/sl （q） with the abdominal aorta（AA） of the angle（a） for statistical analysis. Results： The angle between the SMA and the AA of the lesion group was significantly smaller. The difference between the two groups a, sl, s2, s2/sl was statistically significant. Conclusion： 16-slice spiral CT can clearly show the shape of LRV measured values to assess the degree of LRV compression narro- wing. It shows the important application value in the clinical diagnosis and treatment.
