摘　　要：目的探讨彩色多普勒超声（CDFI）检测胡桃夹综合征（NCS）的应用价值。方法分析30例经CT或DSA证实为NCS患者的肠系膜上动脉（SMA）与腹主动脉（AAO）夹窟、左肾静脉（uW）跨SMA与AAO夹角处内径（d）及峰值流速（Vd）、近肾门段内径（D）及峰值流速（VD），计算D／d比值、Vd／VD比值。结果30例患者中28倒CDFI清楚显示LRV，2例因肠胀气LRV显示不清，LRV显示率为93.3％。28例中6例SMA与AAO夹角在20°-30°之间。16例在150-200之间，6例〈10°0。28例左肾静脉跨SMA与AAO夹角处受压变窄，近肾门段扩张，呈“鸟嘴”征，D／d比值均3．0，Vd／VD比值均4．0。结论SMA与AAO夹角小和左肾静脉受压征是超声诊断NCS的重要征象，有助于NCS的准确诊断。Objective To discuss the clinical＇ value of diagnosing nut cracker syndrome （NCS） with color Doppler flow imaging （CDFI）.Methods Analysing the aortomesenteric angle, the left renal Vein （LRV） diameter （d） and the peak velocity （Vd） between the aortomesenteric angle, the proximal LRV diameter （D） and the peak velocity （VD）,and calculating D/d ratio and Vd/VD ratio of 30 patients who were confirmed by CT or DSA with NCS. Results LRV was clearly displayed with CDFI in 28 cases of 30 patients. Two cases were showed unclearly because of intestinal flatulence, so the ultrasonography display rate of LRV was 93.3%. In 28 cases, the aortomesenteric angles were 20°-30°in 6 cases, 15°-20°in 16 cases, and less than 10°in 6 case. In 28 cases, LRVs between the aortomesenteric angle were narrowed due to the superior mesenteric artery （SMA） compression, expanded in the proximal parts, and displayed＂beak＂signs, in which （D/d） ratios were greater than 3.0, （Vd/VD） ratios were greater than 4.0. Conclusions The small angle and the symptoms of LRV obstruction are important characteristics of Ultrasound diagnasis,which contribute to accurate diagnosis of NCS.
