超声对小儿肠套叠的诊断价值

Significance of ultrasound diagnosis for children's intussusception

目的探讨彩色多普勒超声小儿肠套叠的超声声像图特征及其诊断价值。方法回顾性分析85例小儿肠套叠的声像图表现、病史和临床表现,并总结出其声像图特征。结果85例小儿肠套叠中有77例为典型的特征性的肠套叠声像图,声像图表现为横切面呈"同心圆"征,纵切面呈"套筒"征;另8例肠套叠声像图不典型,声像图表现为"假肾"征和不规则型肿块。结论超声检查是诊断小儿肠套叠的首选影像学诊断方法。

Objective To investigate the ultrasound diagnostic value for children intussusception through color doppler flow imaging （CDFI）. Methods The ultrasonographic characteristics, medical history and clinical manifestation in 85 cases of children＇ s intussusception were retrospectively analyied,and their characteristics of CDFI were summarized. Results In 77 cases whose ultrasonic features were ypical, the main characteristics of CDFI was that the cross section showed ＂concentric circles sign＂, while the longitudinal section showed＂ sleeve sign＂. In another 8 cases of intussusception whose ultrasonic features were not typical, ultrasonography showed ＂false kidney sign＂ and irregular mass. Condusion Ultrasonography is the first choice of imaging diagnostic methods for children＇ s intussusception.
