Two case reports: Early detection of amniotic band syndrome by adhesion between hand and umbilical cord at 11 to 14 weeks' gestation

Abstract

Rationale: The significant ultrasonic characteristics of amniotic band syndrome (ABS) are the malformations of fetal affected parts and the band-like echoes in amniotic cavity. This article first suggests that the fetal hand adhered to umbilical cord with restricted movement provides some values in the diagnosis of ABS in early gestational weeks especially when the fetal malformation is not obvious and amniotic band is thin and fine.

Patient concerns: Two pregnant women had no discomfort and underwent routine ultrasound examination at 11 to 14 gestational weeks.

Diagnosis: Only the fetal hand adhered to umbilical cord with restricted movement was detected during the first ultrasound examination at 11∼14 gestational weeks, and the floating band-like echos were detected in the amniotic cavity with follow-up examinations 2 to 3 weeks later. Both of the 2 fetus were diagnosed as ABS by ultrasound INTERVENTIONS:: The two pregnant women underwent the prenatal counseling and were recommended closely follow-up and further examination.

Outcomes: Two fetuses died in utero between 17 and 19 weeks. After induction of labor, it was found that the hands and umbilical cord of the fetuses were wrapped by amniotic bands, which was proved pathologically as ABS.

Lessons: The adhesion of the fetal hand and umbilical cord is an important ultrasonic sign suggesting ABS with poor prognosis in early pregnancy. We hope that this study can provide some guidance for the early diagnosis of ABS during 11 to 14 week's ultrasound examination.
