The value of five - stage combined double - aortic arch incision in prenatal screening of low risk fetus

Objective: To study how to check the difficulty of fetus heart examination in low risk fetus structure screening during the second trimester, and to explore how to use two-dimensional ultrasonography and color Doppler imaging to maximize the detection rate of fetal heart abnormalities The more standardized, effective and rapid inspection methods. Methods: Pregnant women who were screened for fetal structure during 18-24 weeks’ gestation were enrolled in this study. Fetal heart was routinely screened at the third level using fetal two-dimensional section technique and color Doppler imaging. Fetal heart of each case using the “fetal heart ultrasound 5 section basic section combined with double-aortic arch section method” were observed. From the bottom up are: 1, transverse section of the abdomen; 2, dual inflow section; 3, left ventricular outflow tract section; 4, right ventricular outflow tract section; 5, three vascular section; Discovery of Abnormal or Suspicious Anomalies Further append requests for this fetal line of echocardiography are directed to the fourth level of fetal heart screening. And some serious cardiac abnormalities, or combined with multiple organ malformation fetus specimens taken basic anatomical control analysis, and a large number of late follow-up control analysis. Results: This method can effectively improve the detection rate of fetal heart abnormalities. Conclusion: The method is used to instruct the ultrasound doctor to detect the fetal heart abnormality during the screening of the third-level structure of the fetus with low-risk during pregnancy, which can effectively reduce or avoid the missed diagnosis.
