The Value of Prenatal Systematic Ultrasonic Examination of Fetal Structural Abnormality in Diagnosing Fetal Structural Abnormality

Abstract

In order to explore the value of prenatal systematic ultrasound examination of fetal structural abnormality in the diagnosis of fetal structural abnormality, this paper retrospectively analyzed 200 cases of fetal abnormality referrals from December 2017 to December 2019 in the prenatal systematic ultrasound examination of the designated hospital in this study of pregnant women. By sorting, summarizing and summarizing the actual conditions of the systematic ultrasound examination of each prenatal fetal abnormal section, this study calculated, recorded and analyzed the detection rate, missed diagnosis rate, sensitivity, and specificity of the systematic ultrasound examination of structural abnormality, and then discussed the value of prenatal systematic ultrasound in the diagnosis of fetal structural abnormality. The results showed that, 185 cases were detected out of 200 fetal abnormality with the detection rate of 92.5%; missed diagnosis rate is 7.3%; detection sensitivity is 87.43%; and specificity is 76.58%. Among them, the detection rate of malformations of different diseases from high to low is cardiovascular system (97.54%), nervous system (93.16%), respiratory system (90.62%), facial system (87.54%), and urinary system (85.47%). Therefore, the prenatal systematic ultrasound fetal structural abnormality examination for pregnant women can achieve good diagnostic results, can provide pregnant women with fetal structural abnormality the opportunity to terminate pregnancy early, and effectively reduce the birth of structural abnormal fetuses and the burden of family and society, having important clinical significance and reducing.
