摘要
目的探讨高频超声诊断小儿肠系膜淋巴结炎的诊断价值。方法使用7.5～12 MHz高频探头,对因腹痛的患儿进行超声检查,并进行回顾性分析。结果 80例患儿的超声声像图主要表现:多位于脐周和(或)右下腹,边界清,内部回声均匀,椭圆形、串珠状、堆状分布,皮髓质分界较清晰,直径10～30 mm,长/横径≥2。CDFI可见较丰富血流信号,分布呈淋巴结门型,条状规则分布。位置较深的可探及点状血流,表浅者可见自淋巴门,向淋巴结内呈树枝状分布血流信号。急性期时,髂窝、肠间隙可探及少量游离液性暗区。结论用高频超声诊断小儿肠系膜淋巴结炎具有检查便捷、诊断率高、无创、定位准确等优点,并具有可以对其他疾病进行鉴别诊断的特点,值得临床推广应用。
Objective To disscuss the clinical value of high frequency ultrasound in the children mesenteric lymphadenitis diagnosising. Methods Inspected children who suffered from abdominal pain with 7.5-12 MHz high frequency transducers, and then retrospective analysis the clinical data. Results The main sonography of 80 ehidren with pediatric mesenteric lymphadenitis before therapy was shown as： Most of the lymph node was located in periumbilical and （or） right lower quadrant abdominal, boundary clear, internal echo uniform, oval, beaded arrangement, pile of shape distribution, and clear dividing line in corticomedullary, 10-30 mm in diameter, long/short axis≥2. Color Multi Doppler ultrasound probed lymph node type door and strip distribution rich blood flow. In the acute phase, a few free liquid dark area could be detected in iliac nest and bowel clearance. Conclusion The high frequency ultrasound is non-invasive,economical,simple, repeatable inspection in diagnosising children＇s mesenteric lymphadenitis,and can identify mesenteric lymphadenitis from other diseases, is worthy of popularizing.
