RESUMO

Objective To investigate the clinical significance of ultrasonography combined with scrological detection in the screening of trisomy 21.Methods The clinical data of 2 281 pregnant women who have received prenatal ultrasound examination,scrological detection and prenatal diagnosis in our hospital from January 2014 to March 2016 were retrospectively analyzed.All the fetuses had ultrasound abnormal or/and 21-trisomy syndrome high risk with scrological detection.The detection rate of trisomy 21 was observed when ultrasonography combined with scrological detection.The detection rate was compared between the two methods respectively.Results Among 2 281 pregnant women who received prenatal diagnosis,68 fetuses with trisomy 21 were diagnosed by fetal karyotype,the detection rate was 2.98% (68/2 281);There were 879 cases of merely ultrasound abnormal,27 of them were trisomy 21,the detection rate was 3.07% (27/879);1 336 cases were merely high risk of 21-trisomy syndrome,34 of them were trisomy 21,the detection rate was 2.54% (34/1 336);There were 66 cases of both ultrasound abnormal and 21-trisomy syndrome high risk,7 of them were trisomy 21,the detection rate was 10.61% (7/66).The method of joint use is higher than the independent method,with statistically significant difference (P < 0.05).Conclusions Ultrasonography combined with scrological detection have good application value in the screening of trisomy 21 syndrome.
