目的讨论产前胎儿系统超声检查对胎儿形态、结构畸形筛查的诊断和价值。方法对7826例(18w-40w)中晚期胎儿进行彩超产前胎儿结构和形态的系统筛查,并且按照英国胎儿基金会超声检查规范,采集21幅标准图片并进行图片存储,对产后诊断结果进行回顾性分析。结果产前超声系统筛查出192例畸形胎儿,经引产或出生后证实,漏诊8例,诊断检出率95.83%,单发畸形162例(162/192,84.37%),多发畸形27例(27/192,14.06%),双胎畸形3例(3/192,1.56%)。结论胎儿系统超声检查对胎儿形态、结构畸形的诊断具有重要的价值,它是产前诊断胎儿畸形的首选方法。
Objective To discuss the diagnosis and value of fetal prenatal fetal ultrasound screening in fetus morphology and structural deformity screening. Methods A total of 7826 cases (18w-40w) of middle-late stage fetus were screened by color-prenatal fetal structure and morphology. According to the British Fetal Foundation ultrasound examination standard, 21 standard pictures were collected and stored. The results of postpartum diagnosis Retrospective analysis. Results 192 prenatal ultrasound screening of fetal malformation fetus confirmed by induction of labor or after birth, missed diagnosis in 8 cases, the diagnostic rate was 95.83%, 162 cases of single malformations (162 / 192,84.37%), multiple deformities in 27 cases 27 / 192,14.06%), twins deformity in 3 cases (3 / 192,1.56%). Conclusion Fetal ultrasound examination has important value in the diagnosis of fetal morphology and structural deformity. It is the preferred method of prenatal diagnosis of fetal malformations.
