超声影像技术诊断胡桃夹综合征的临床价值探究

Clinical Value of Ultrasonography in Diagnosis of Nutcracker Syndrome

目的:通过分析胡桃夹综合征患者左肾静脉超声影像特征和规律,探讨超声影像技术诊断胡桃夹综合征的价值。方法:选取笔者所在医院收治的29例胡桃夹综合征患者为观察组,30例健康体检的志愿者为对照组,采用超声影像技术检查两组患者近肾段及狭窄段左肾静脉内径及血液峰值流速等,并计算超声影像技术诊断胡桃夹综合征的灵敏度和特异性。结果:观察组患者肠系膜上动脉及腹主动脉间夹角、左肾静脉狭窄段内径、最窄处内径(D2)和扩张部最宽处内径(D1)的比值(D2/D1)均明显偏小,差异均有统计学意义(P<0.05);超声诊断胡桃夹综合征的灵敏度为82.76%(24/29),特异性为80.00%(24/30)。结论:通过超声影像技术检查左肾静脉内径和血流速度等指标能够快速、准确诊断胡桃夹综合征,值得临床推广使用。

Objective:To investigate the value of ultrasonography in the diagnosis of nutcracker syndrome.Method:29cases of nutcracker syndromepatients in the author’s hospital were selected as the observation group,30healthy volunteers were selected as the control group,the ultrasound imagingexamination was used to examine the inner diameter of the left renal vein and the peak blood flow rate in the renal segment and the narrow segment of two groups,and the sensitivity and specific were calculate.Result:Compared with the control group,the observation group of patients with superior mesenteric artery andabdominal aorta,the angle between the left renal vein,the narrowest diameter(D2)and the expansion of the width diameter ratio(D1)(D2/D1)were significantlysmaller,the differences were statistically significant(P<0.05).The sensitivity of ultrasound in diagnosis of nutcracker syndrome was82.76%(24/29),the specificitywas80%(24/30).Conclusion:The left ventricular diameter and blood flow velocity can be quickly and accurately diagnosed by ultrasonography,which is worthy ofclinical application.
