摘　　要：目的探讨高频彩超显像对小儿急性阑尾炎的诊断价值。方法术前应用高频超声及彩色多普勒血流显像诊断小儿急性阑尾炎90例，分析其声像图及彩色血流信号特征并进行分类，并将观察结果与手术及病理结果对照。结果该组90例病例全部在24小时内手术，并经手术病理证实，诊断符合率为90％（81／90），误诊3例，漏诊6例。81例中，单纯性阑尾炎23例，化脓性阑尾炎29例，坏疽性及穿孔性阑尾炎14例，阑尾周围脓肿15例。CDFI显示阑尾及周围组织血流信号不同程度增多。结论高频彩超检查对小儿急性阑尾炎的诊断有重要意义，方便快捷，可作为首选，值得推广。Objective To explore the diagnostic value of high-frequency ultrasonography and color Doppler flowing imaging （ CDFI ） for childhood acute appendicitis. Methods High-frequency ultrasonography and CDFI were preoperatively performed to diagnose acute appendicitis in 90 children. The sonographic images and the features of color flow signals were analyzed and then classified; the results were compared with the surgical and pathological findings. Results All the children received surgical treatment within 24 hours and the diagnosis of appendicitis was confirmed pathologically, with a correct diagnostic rate of 90% （ 81/90 ）. 3 children were misdiagnosed and 6 missed diagnosis. 23 of the 81 children had simple appendicitis, 29 had suppurative appendicitis, 14 had gangrenous and perforated appendicitis, and 15 had appendiceal abscess. CDFI showed the blood flow signals enhanced in the appendix and its surrounding tissue to a varying degree. Conclusons High-frequency ultrasonography is of important significance in the diagnosis of childhood acute appendicitis. It is convenient and quick for diagnosis, can be used as the first choice of diagnosis, and is worth popularizing.
