目的探讨高、低频超声联合应用在老年急性阑尾炎患者中的诊断价值。方法对2013年在我院急救中心就诊的62名老年急性阑尾炎患者，先用低频超声检查，后行高频超声检查，确定阑尾位置、走形、回声及血流情况，做出急性阑尾炎的超声诊断。结果62名老年急性阑尾炎患者中，低、高频联合超声诊断检出58例，漏诊3例，误诊1例，与术后病理诊断符合率为93.5%。结论低频及高频超声联合检查急性阑尾炎分别从整体和局部入手，起到互补的作用，从而提高阑尾炎的显示率及诊断的准确性。

ObjectiveTo explore the diagnostic value of high frequency combined low frequency color doppler ultrasonography for elderly patients with acute appendicitis. MethodsIn 2013, 62 elderly patients with acute appendicitis from emergency center of our hospital examined successively with low frequency ultrasound and high frequency ultrasound. The position of appendix, shape, echo and blood flow of appendix were determined, and then ultrasonography diagnosis of acute appendicitis was made. ResultsAmong 62 elderly patients with acute appendicitis, 58 cases were detected under the use of high frequency combined low frequency ultrasonography examination, 3 cases were missed diagnosis and misdiagnosis in 1 cases, the total coincidence rate between ultrasonography diagnosis and pathologic diagnosis was 93.5%. ConclusionThe low frequency and high frequency ultrasonography in acute appendicitis were from the overall and partial angle, respectively, the combination of the two can improve accuracy rate and the accuracy of the diagnosis of acute appendicitis.
