高频超声经腹壁对小儿肠系膜淋巴结炎诊断分析

目的探讨使用高频彩色多普勒超声经腹壁诊断小儿肠系膜淋巴结炎的临床应用价值。方法对56例急性腹痛的患儿和30例对照组的儿童进行超声检查，观察记录淋巴结分布的部位，形态，测量长短径（L／S），并观察血流情况，且测定血流的阻力指数（RI）。结果所有儿童均可探及到肠系膜淋巴结，腹痛患儿超声表现为右下腹及脐旁可见数个大小不等的低回声椭圆形团块，边界清，内部回声均匀，均〉2cm，血流信号沿淋巴门分布，RI〉0．60。结论使用高频超声能为临床诊断急性肠系膜淋巴结炎提供可靠依据。

The diagnosis analysis of mesenteric lymphnoditis with high frequency ultrasonography in children

Objective To investigate the clinical diagnosis value of mesenteric lymphnoditis with high frequency ultrasound in children. Methods 56 cases of acute abdominal pain received ultrasound scan for observing the location and shape of mesenteric lymphnoditis, and measuring the ratios of width to height, and observing the information of blood flow, and measuring the resistent index (RI), comparied with the 30 cases of normal group. Results The mesentery lymphaden can be detected by uhrasonography,the nodules are some irregular or elliptical and hypoechoic lump with well-defined margin and homogeneous echo in right lower abdomen and paraumbilical. The rationes of width to height of the nodults are > 2 cm, blood flow signal distributed through the hilum of lymph gland, RI > 0. 60. Conclusion The high frequency ultrasond is a reliable method in diagnosing the acute mesentery lymphadenitis.
