彩色多普勒超声诊断小儿肠系膜淋巴结炎的价值

目的:探讨高频彩色超声检查在诊断小儿肠系膜淋巴结炎中的临床价值。方法:对2~12岁62例临床诊断为肠系膜淋巴结炎的小儿进行腹部超声检查,观察肠系膜淋巴结。结果:62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,皮髓质界限清楚,淋巴门结构未见破坏。彩色多普勒血流量显像(color Doppler flowi maging,CDFI)显示肿大淋巴结内血流信号增多,可探及低速低阻力型动脉频谱。结论:高频彩色超声检查便捷,能准确诊断小儿肠系膜淋巴结炎,可作为首选影像学诊断方法,在临床上有重要应用价值。

Value of color doppler ultrasound in the diagnosis of mesenteric lymphadenitis in children

Objective：To investigate the value of high-frequency color doppler ultrasound in the diagnosis of mesenteric lymphadenitis in children.Methods：Abdominal color doppler ultrasound were applied to observe the mesenteric lymph nodes on 62 mesenteric lymphadenitis patients who were of 2-12 years old.Results：All cases showed different degrees of swollen mesenteric lymph nodes with regular shapes,clear boundaries,corticomedullary differentiation were easy and lymphoid gate structures were complete.However,blood flow signals increased inside the enlarged lymph nodes under the color doppler blood flow imaging,low-speed and low-resistance artery spectrum were also shown.Conclusion：High-frequency color doppler ultrasound examination is convenient,accurate in the diagnosis of mesenteric lymphadenitis in children,and can be used as a primary imaging technique in the diagnosis of mesenteric lymphadenitis.
