目的探讨高频超声对小儿肠系膜淋巴结炎的诊断价值。方法应用彩色多普勒超声对280例腹痛小儿常规进行全腹检查,排除其他疾病,重点扫查右下腹及脐周淋巴结的数量、大小及形态,并对二维图像以及多普勒血流显像进行回顾性分析。结果280例患儿在脐周及腹腔内可探及数枚椭圆形低回声结节,长径与短径之比均>2,长径>1.0 cm,短径>0.5 cm。彩色多普勒超声显示,其内均探及血流信号,阻力指数0.5~0.63之间。结论高频超声对小儿肠系膜淋巴结炎的诊断及治疗后的随访观察有重要价值。
Objective To investigate the diagnostic value of high frequency ultrasound in children with mesenteric lymphadenitis. Methods 280 patients with abdominal pain were routinely examined by color Doppler ultrasonography. All other diseases were excluded. The number, size and shape of the right lower quadrant and umbilical lymph nodes were examined. Two-dimensional images and Doppler flow imaging Like a retrospective analysis. Results A total of 280 cases of children with oval hypoechoic nodules were found in the umbilical cord and peritoneal cavity. The ratio of long diameter to short diameter was> 2, the diameter was> 1.0 cm, and the diameter was> 0.5 cm. Color Doppler ultrasound showed that both the probe and blood flow signal, resistance index between 0.5 ~ 0.63. Conclusion High-frequency ultrasound diagnosis of children with mesenteric lymphadenitis and follow-up after treatment of great value.
