本文研究了1982年1月1日～1988年12月31日间131例有超声异常的病例,于孕14～39周完成遗传学羊膜腔穿刺术,获得117例胎儿核型,有下述异常所见:①宫内生长迟缓(IUGR),61例;②胎儿畸形,71例;③羊水量(AFV)异常,60例。117例中,查出染色体异常19例(16.2％)。有畸形病例的非整倍体出现频率比无畸形大2.5倍。胎儿特殊畸形和特异的染色体异常之间,无相关关系。匀称的 IUGR 非整倍体
In this paper, 131 patients with ultrasound abnormalities between January 1, 1982 and December 31, 1988 were enrolled in the study. Genetics of amniocentesis was performed 14-14 weeks gestation, and 117 fetuses were found with the following abnormalities See: ① intrauterine growth retardation (IUGR), 61 cases; ② fetal malformations, 71 cases; ③ amniotic fluid volume (AFV) abnormalities, 60 cases. In 117 cases, 19 cases (16.2%) of chromosomal abnormalities were detected. Aneuploidy cases of malformations appear frequency 2.5 times larger than without deformity. There was no correlation between fetal special deformities and specific chromosomal abnormalities. Shapely IUGR aneuploidy
