THE VALUE OF PRENATAL FOUR-DIMENSIONAL ULTRASOUND IN THE DIAGNOSIS OF FETAL CONGENITAL HEART DISEASE
Objective To assess the value of four-dimensional ultrasound in the auxiliary diagnosis of fetal congenital heart disease.Methods From 2010 to 2015,a total of 879 high risk pregnant women were selected to undergo two and four dimensional ultrasound to evaluate the clinical value of prenatal four-dimensional ultrasound in auxiliary diagnosis of fetal congenital heart disease (CHD) taking the anatomical structure after the induction of labor or postnatal follow-up as the gold standard.Results Combined application of these two B ultrasound examination,38 cases of CHD were accurately diagnosed,missed diagno sis in one case,and misdiagnosis in three,the diagnostic sensitivity,specificity,and diagnostic consistency of Kappa being 97.44％,99.64％ and 0.948,respectively.Applying two dimensional ultrasound,35 cases of CHD were diagnosed correctly,missed diagnosis in four cases,and misdiagnosis in eight cases,the diagnostic sensitivity,specificity and the diagnostic consistency Kappa value being 89.74 ％,99.05 ％,and 0.847.The Kappa value of combined two-and four-dimensional ultrasound in the diagno sis of CHD was higher than that using two-dimensional ultrasound alone,the difference was statistically significant (x2 =3.879,P＜0.05).Conclusion Four-dimensional ultrasound has a greater value in the auxiliary diagnosis of fetal congenital heart disease,which shows high consistency with clinical diagnosis results.
