摘要
目的探讨高频超声在诊断小儿肠系膜淋巴结炎中的临床价值。方法对98例肠系膜淋巴结炎的患儿进行腹部超声检查，观察肠系膜淋巴结的分布、多少、大小、形态及内部回声情况，长径与短径比（L／D）、血流、RI值。结果98例患儿均有不同程度的肠系膜淋巴结肿大，肿大的淋巴结形态规则，边界清晰，皮髓质界限清晰或欠清晰，淋巴门结构未见破坏。彩色多普勒血流量显像（colorDopplerflowimaging，CDFI）显示肿大淋巴结内血流信号丰富，频谱多普勒（Pw）探及低速低阻力型动脉频谱，L〉1．0em，D〉0．5cm，LID值介于2．1～2．8之间，收缩期峰值流速（PSV）介于8～20cm／s之间，阻力指数（RI）介于0．49～O．66之间。结论高频超声检查便捷，盂创伤性，在小儿肠系膜淋巴结炎的诊断中有重要的临床诊断价值。
Objective To investigate the clinical value of high-frequency ultrasound in the diagnosis of mesenteric lymphadenitis in children. Methods 98 children, including 66 boys and 32 girls, aged 2 to 7 years old, with an average of （5.0±0.8） years, who presented with abdominal pain or recurrent abdominal pain and, clinically, were diagnosed with mesenteric lymphadenitis, underwent abdominal ultrasound examination, with which the statuses of mesenteric lymph nodes, in terms of distribution, number, size, morphology, internal echo, ratio of long diameter versus short diameter ratio, blood flow, and RI values were observed in this work. Results The enlargement of mesenteric lymph nodes to varying degrees appeared in all 98 patients. The shape of enlarged lymph nodes was regular, with clear boundary, the corti- comedullary boundary was clear or unclear, and the hilar structures were damaged. Color Doppler blood flow imaging dis- played rich blood flow signals within the lymph nodes, Spectral Doppler probed a low--speed low--resistance arterial spectrum： L〉 1.0 cm, D〉 0.5 cm, L/D value ranged between 2.1 to 2.8, the peak systolic velocity （PSV） between 8- 20 cm/s, resistive index （RI） ranged from 0.49 to 0.66. Conclusion The high-frequency ultrasound is convenient, non- invasive, which has an important value in the diagnosis of mesenteric lymphadenitis in children.
