彩色普勒超声诊断肠套叠的临床价值

目的探讨彩色普勒超声检查对小儿肠套叠的临床诊断价值。方法选择2007年1月至2012年12月本院住院的小儿肠套叠病例52例,回顾性分析其二维超声超声表现及彩色多普勒检测套入肠管彩色血流的特征。结果肠套叠的超声特征改变为包块形态规则,套叠处的肠管横切面呈＂同心圆＂,纵切面呈＂假肾征＂,40例显示出肠壁血流信号,阻力指数明显增高,12例检测未到血流信号,有明显肠梗阻、腹膜炎表现及继发性肠套叠等情况者提示临床不宜灌肠复位;所有病例经X线空气灌肠复位、超声监视下进行水压灌肠复位、手术治疗后证实,4例出现肠坏死,34例复位成功,3例合并肠息肉,3例合并肠憩室。结论彩色多普勒超声在诊断肠套叠具有较高的特异性、无创性、高度敏感性和特异性,是目前首选的影像学检查方法。

Color doppler ultrasound diagnosis intussusception clinical value

Objective To study the color.doppler ultrasonography pediatric intussusception clinical diagnostic value.Method From 2007 to December 2012,52 intussusception cases were analyzed retrospectively,the sonographic findings of two-dimensional ultrasound and color doppler detection set into the characteristics of color doppler loops.Results Intussusception sonographic features changeel morphological rules for bag piece,set in a dilated bowel cross-section fold in concentric circles,＂longitudinal section＂ ＂false renal levy ＂,40 cases showed blood flow signals wiggle,significantly higher resistance index,12 patients not to flow signal detection,had apparent obstruction,peritonitis manifestations and secondary intussusception the hint as clinical unfavorable enema reset;All cases of X-ray air enema reset,ultrasound monitor hydraulic enema under reset and surgical treatment,4 cases confirmed after intestinal necrosis,34 cases reset success,3 cases,3 cases merger intestinal polys merger diverticula.sensitivity and specificity,was the preferred imaging examination method.Conclusion Color doppler ultrasound in the diagnosis of intussusception has high specificity,non-invasive,high.
