目的 了解胎儿畸形的发生率以及超声诊断的符合率 ,为早期临床干预提供依据。方法 采用彩色多普勒超声仪随机对 5 2 1 3例孕 1 9～ 42周胎儿进行多系统的常规探查 ,所得结果与产后尸体解剖及临床对照。结果 共查出胎儿畸形 2 2 1例 ,畸形率为 42 .3 9‰。胎儿畸形前 5位依次为 :胎儿水肿 ( 2 7.1 5 % )、体表 ( 1 7.2 0 % )、心血管( 1 6.2 9% )、神经管 ( 1 0 .41 % )、泌尿系 ( 9.95 % )。产后对照 ,畸形的超声诊断符合率达 90 %以上的有胎儿水肿、心血管、腹壁裂及神经管畸形。结论 胎儿畸形并非少见 ,超声及早发现对优生尤为重要
Objective To understand the incidence of fetal malformations and the coincidence rate of ultrasound diagnosis, providing the basis for early clinical intervention. Methods A total of 5231 fetuses, aged from 19 to 42 weeks, were routinely investigated by color Doppler sonography. The results were compared with postnatal cadaveric anatomy and clinical control. Results A total of 21 cases of fetal malformations were found, with a deformity rate of 42.39 ‰. The top five fetal malformations were as follows: fetus edema (7.15%), body surface (7.220%), cardiovascular (1. 6.29%), neural tube (10.41%), urinary tract ). Postpartum control, abnormal diagnosis of ultrasound in line with the rate of 90% or more of fetal edema, cardiovascular, abdominal wall and neural tube defects. Conclusion Fetal deformity is not uncommon, and early detection of eugenics is particularly important for eugenics
