高低频超声结合在诊断急性阑尾炎中的临床价值

Evaluation of high-and low-frequency ultrasound in the diagnosis of acute appendicitis

目的:探讨高频超声和低频超声联合应用在诊断急性阑尾炎中的临床价值。方法:对2008年5月～2010年5月我院临床怀疑急性阑尾炎者先行低频超声扫查,然后联合应用高频超声对比扫查。对123例术后病理证实为急性阑尾炎的超声图像进行回顾性分析。结果:低频超声诊出阑尾炎88例,符合率71.5%,低频超声联合高频超声诊出阑尾炎109例,符合率88.6%。阑尾长轴切面呈腊肠样盲端结构,短轴切面呈"同心圆"征。结论:高、低频超声联合应用能有效提高急性阑尾炎的超声诊断符合率,为临床治疗方案的判定提供重要的参考依据,在诊断急性阑尾炎中有重要的临床意义。

Objective：To evaluate the clinical value in the diagnosis of acute appendicitis using high-frequency ultrasound combined with low-frequency ultrasound.Methods：Clinical suspicion of acute appendicitis on the first low-frequency ultrasound scanning thereof,and then comparing combined high frequency ultrasound scanning.123 cases were pathologically confirmed acute appendicitis ultrasound images were analyzed retrospectively.Results：Low-frequency ultrasound diagnosed 88 cases of appendicitis,in line with rates of 71.5%,low frequency ultrasound combined with high frequency ultrasound diagnosed 109 cases of appendicitis,in line with rates of 88.6%.The long axis of the appendix sausage-like blind-side cut surface structure,the short axis cut surface ＂concentric circles＂ sign.Conclusion：High and low frequency ultrasound can improve the application of ultrasonic diagnosis of acute appendicitis the rate determined for the clinical treatment programs provide important diagnostic evidence,has important clinical significance in the diagnosis of acute appendicitis.
