2、值。结果彩色多普勒超声可清晰显示左肾静脉自肾门处注入下腔静脉的全程。本组8例胡桃夹综合征患者经多角度、多切面扫查均见左肾静脉穿越腹主动脉后方与腰椎之间隙汇入下腔静脉，狭窄处左肾静脉内径为(1．5±0．4)mm，血流速度为(154．5±30．1)cm/s;扩张处左肾静脉内径为(8．7±1．4)mm，血流速度为(22．8±3．4)cm/s;左肾静脉内径、血流速度比值分别为1∶(6．5±0．5)及1∶(7．2±0．9)。结论彩色多普勒超声检查可准确评价左肾静脉走行变异导致的左肾静脉扩张及血流动力学变化，对临床诊断、治疗后胡桃夹综合征具有重要的应用价值。【关键词】超声检查，多普勒，彩色;肾静脉;畸形
