Analysis of pregnancy outcome of prenatal ultrasonic diagnosed solitary lateral ventricular asymmetry / 中国医学影像技术

ABSTRACT

Objective: To analyze the pregnancy outcome of prenatal ultrasonic diagnosed fetal solitary lateral ventricular asymmetry. Methods: Imaging data and pregnancy outcome of 191 fetuses with prenatal ultrasonic diagnosed solitary lateral ventricle asymmetry were retrospectively analyzed. The infants were followed up for 6-12 months after birth, and infant neurodevelopmental assessment was used to assess whether there were abnormal reactions and behaviors. Results: Among 191 fetuses, 98 were found with asymmetric (98/191, 51.31%), while 93 were found with unilateral ventricular broadening (93/191, 48.69%). With the development of pregnancy, the width of lateral ventricle became normal in 130 fetuses (130/191, 68.06%), remained as former in 58 fetuses (58/191, 30.37%) but further expanded in 3 fetuses (3/191, 1.57%). In addition, 2 cases underwent umbilical cord blood puncture chromosome karyotype examination, 1 was trisomy 18, the karyotype was 47, XN, +18, and the other was normal. Normal delivery achieved in 189 fetuses, while 2 received labor induction, 1 with chromosomal karyotype abnormality and the other was considered as unilateral lateral ventricular progressive broadening combined with prenatal MRI suspected bilateral cerebral hemisphere dysplasia. Conclusion: Fetal solitary unilateral unilateral ventricular asymmetry has no obvious impact on fetal growth and development fetuses. The pregnancy outcome and prognosis mainly depends on the intrauterine progress of lateral ventricular width, which need to be closely monitored and followed-up.
