彩色多普勒超声在非高危胎儿产前心脏筛查中的意义研究

Study the significance of color Doppler ultrasound in prenatal cardiac screening of non-high risk fetus

目的分析彩色多普勒超声在非高危胎儿产前心脏筛查中的意义。方法选取500例非高危胎儿设为研究组,另选取同期70例高危胎儿设为对照组。两组胎儿均使用彩色多普勒超声仪进行产前心脏筛查。分析非高危胎儿的产前心脏筛查结果,比较两组胎儿心脏畸形诊断准确率。结果500例非高危胎儿的多普勒超声产前心脏筛查检出49例心脏畸形胎儿,检出率为9.80%,其中5例室间隔缺损,8例房间隔缺损,6例左心发育不全,8例法洛四联症,5例完全性心内膜垫缺损,6例完全性大动脉转位,11例主动脉瓣狭窄。研究组产前检出心脏畸形49例(9.80%),产后实际心脏畸形50例(10.00%),诊断准确率为98.00%(49/50);对照组产前检出心脏畸形20例(28.57%),产后实际心脏畸形20例(28.57%),诊断准确率为100.00%(20/20);两组诊断准确率比较差异无统计学意义(P>0.05)。结论彩色多普勒超声在非高危胎儿和高危胎儿产前心脏筛查中的诊断率均很高,提示即使是症状轻微的心脏疾病也能够使用彩色多普勒超声准确及时的诊断出来,在临床上具有重要的临床价值,值得推广。

Objective To analyze the significance of color Doppler ultrasound in prenatal cardiac screening of non-high risk fetus.Methods 500 non-high-risk fetuses were selected as the study group,and 70 high-risk fetuses during the same period were selected as the control group.Both groups underwent prenatal cardiac screening using color Doppler ultrasound.The results of prenatal cardiac screening in non-high-risk fetuses were analyzed,and the diagnosis accuracy of fetal cardiac malformation was compared between the two groups.Results Through prenatal cardiac screening of 500 non-high risk fetuses,49 fetuses were found to have cardiac malformation,the detection rate was 9.80%,among which 5 fetuses had ventricular septal defect,8 fetuses had atrial septal defect,6 fetuses had left ventricular hypoplasia,8 fetuses had tetralogy of Fallot,5 fetuses had complete endocardial cushion defect,6 fetuses had complete transposition of great arteries,and 11 fetuses had aortic stenosis.In the research group,49 cases(9.80%)of cardiac malformations were detected prenatally,and 50 cases(10.00%)of actual postpartum cardiac malformations were detected,with a diagnostic accuracy rate of 98.00%(49/50);in the control group,20 cases(28.57%)of cardiac malformations were detected prenatally,and 20 cases(28.57%)of actual postpartum cardiac malformations were detected,with a diagnostic accuracy rate of 100.00%(20/20).There was no statistically significant difference in the diagnostic accuracy between the two groups(P>0.05).Conclusion Color Doppler ultrasound has high diagnosis rate in prenatal cardiac screening of non-high-risk fetus,suggesting that even mild symptoms of heart diseases can be diagnosed accurately and timely,which has important clinical value and is worth popularizing.
