Objective: To investigate the value of ultrasonic prenatal diagnosis of fetal malformations. Methods: Fifty-seven (737) pregnant women aged 18-40 weeks underwent systematic ultrasound examination to screen and diagnose fetal malformations. Results: Among 5 737 pregnant women, 199 cases of various deformities confirmed by induced labor or after birth were diagnosed by ultrasound, 193 cases were diagnosed prenatally, 6 cases were misdiagnosed. The cases of misdiagnosis mainly showed minor deformities and defects. Conclusion: Systemic ultrasonography is an important imaging diagnostic method to show the morphology and structure of fetus and prenatal diagnosis of fetal malformations.
