正常新生儿与先天性甲状腺功能减低症新生儿的甲状腺容积超声研究

Study on thyroid volume ultrasonography of normal neonates and neonates with congenital hypothyroidism

目的:探讨超声在新生儿先天性甲状腺功能减低症诊断中的检查意义。方法:对广西壮族自治区妇幼保健院筛确诊的97例先天性甲状腺功能减低症新生儿进行甲状腺超声扫查,测量甲状腺的大小并计算容积,并观察甲状腺回声及彩色多普勒(CDFI)血流情况,然后与100例正常新生儿的甲状腺对照分析。结果:97例患儿中,57例甲状腺未见明显异常,22例甲状腺明显肿大,2例甲状腺未见明显肿大,但是血流信号丰富,15例甲状腺偏小,1例甲状腺发育不良。结论:超声检查在新生儿甲状腺功能减低症的筛查中起到重要作用,对临床治疗有重要辅助价值。

Objective ： To explore the significance of uhrasonography in diagnosis of neonatal congenital hypothyroidism （ CH ） . Methods： Thyroid ultrasonography was performed among 97 neonates diagnosed as CH definitely in the hospital, the size of thyroid was measured, the thyroid volume was calculated; the echo and blood flow of thyroid were observed by color Doppler ultrasonography, then the results were compared with 100 normal neonates. Results ： Among 97 neonates with CH, no obvious abnormality was found in 57 neonates, obvious swelling was found in 22 neonates, abundant blood flow signals were found in 2 neonates with less obvious swelling, small thyroid was found in 15 neonates, thyroid hypoplasia was found in one neonate. Conclusion： Ultrasonography plays an important role in screening of neonatal CH, which has important auxiliary value in clinical treatment.
