Analysis of prenatal ultrasound diagnosis of amniotic band syndrome in early pregnancy
Objective:To investigate the prenatal ultrasonic diagnostic features of amniotic band syndrome (ABS) in early pregnancy.Methods:The prenatal ultrasound data of a case of a 13+6-week-old fetus with ABS, who was confirmed by induced abortion at the Ultrasound Department of Laizhou Maternity and Child Healthcare Hospital on January 7, 2020, were retrospectively analyzed, and the literature was reviewed.Results:The prenatal ultrasonic diagnostic features of ABS in early pregnancy included limited movement of the left upper limb and feet of the fetus, absence of the right upper limb. In the amniotic cavity multiple slender linear echoes of the amniotic band and the contiguous amniotic sheets were detected, which were connected to the ends of the left finger and both toes respectively.Conclusion:Grasping the prenatal ultrasonographic features of ABS in the first trimester may be helpful in improving the eally detection and diagnosis.
