Application and diagnostic value of color doppler in prenatal cardiac screening

Abstract

Objective To comprehensively analyze the application and diagnostic value of color doppler in prenatal cardiac screening. Methods 1 800 middle-late pregnant women admitted into our hospital from March, 2014 to November, 2016 were selected for prenatal color doppler ultrasound examination. The pregnant inspection area was fully exposed. The fetus development of each system was recorded in detail and were observed and studied. The fetal femur, humerus, cerebellar transverse diameter, placental position, fetal heart rate, head circumference, and echo condition were routinely detected. SPSS20.0 statistical software was used for statistically analyzing the detected data; and the various slices were deposited into the workstation to analyze the correct diagnosis rate of the 1 800 pregnant women. Results Among the 1 800 pregnant women, 66 abnormal fetuses were detected, accounting for 3.67% (66/1 800). The missed diagnosis rate was 3.03% (2/66) and the correct diagnosis rate was 96.97% (64/66). The correct diagnosis rate was far higher than the missed diagnosis rate, with a statistical difference (P < 0.05). Among the 66 malformation fetus, 12 were atrial septum defect (clinical validation 11 cases), 16 ventricular septal defect (clinical validation 16 cases), 9 cases complete endocardial cushion defect (clinical validation 9 cases), 10 cases right heart dysplasia (clinical validation 10 cases), 8 cases aortic valve stenosis (clinical validation 8 cases), 7 cases tetralogy of fallot (clinical validation 8 cases), and 2 cases complete type arteries transposition (clinical validation for 2 cases). Conclusion The application and diagnostic value of color doppler in prenatal cardiac screening is high. Key words: Color doppler; Fetus; Prenatal cardiac screening; Application and diagnostic value
