二维超声在胡桃夹综合征诊断中的应用价值

Application value of two-dimensional ultrasonography in the diagnose of nutcracker syndrome

目的探讨二维超声在胡桃夹综合征诊断中的应用价值。方法选取娄底市第三人民医院2016年12月—2017年12月收治的胡桃夹综合征患者29例作为观察组,另选取本院同期体检健康者30例作为对照组。采用二维超声检测两组受试者腹主动脉与肠系膜上动脉间夹角、左肾静脉狭窄段内径、近肾端受压前最宽处左肾静脉血管内径(D1)及最狭窄处左肾静脉血管内径(D2),并计算比较两组受试者D2/D1及灵敏度和特异度。结果观察组患者腹主动脉与肠系膜上动脉间夹角、D2/D1小于对照组,左肾静脉狭窄段内径短于对照组(P<0.05)。二维超声诊断胡桃夹综合征的灵敏度为82.8%(24/29),特异度为80.0%(24/30)。结论二维超声检测可准确诊断胡桃夹综合征,操作简单,对患者损伤较小,且灵敏度与特异度较高。

Objective To investigate the application value of two-dimensional ultrasonography in the diagnose of nutcracker syndrome.Methods A total of 29 cases of patients with nutcracker syndrome were admitted from December 2016 to December 2017 in the Third People＇s Hospital of Loudi as observation group,and 30 healthy physical examination people were selected as control group.The angle between the abdominal aorta and superior mesenteric artery,the inner diameter of the left renal vein stenosis,the widest left renal vein diameter（D1）and the narrowest left renal vein diameter（D2）before the proximal renal compression were measured and compared by two-dimensional ultrasound,calculated and compared D2/D1,sensitivity and specificity.Results The observation group of angle between the abdominal aorta and superior mesenteric artery,D2/D1 were less than control group,the inner diameter of the left renal vein stenosis was shorter than control group（P0.05）.The sensitivity of two-dimensional ultrasound in the diagnosis of nutcracker syndrome was 82.8%（24/29）,specificity was 80.0%（24/30）.Conclusion Two-dimensional ultrasonography can accurately diagnose the nutcracker syndrome,and it is easy to operate,and with less damage to patients and higher sensitivity and specificity.
