Abstract:
To investigate the prenatal sonographic feature in the early diagnosis of amniotic band syndrome at 11 -14 weeks′ gestation . Methods A retrospective study was conducted to analysis and summarize the ultrasonographic features of 4 fetuses without band‐like echoes in amniotic cavity at 11-14 weeks′gestation ,but verified as amniotic band syndrome in Peking Union M edical College Hospital . Results T wo cases ( cases 1 ,2) showed the fixed head position with skull defect and intracranial structure disorders . Cases 3 and 4 showed one upper limb in a fixed position ,and the hand seemed to adhere to the umbilical cord isolatedly . In addition ,case 1 showed complete chorioamniotic membrane separation . T here were multiple band‐like echoes adhered to body of 3 fetals during the follow‐up scan at 14 -18 weeks . T he parents of cases 1 and 2 chose to terminate the pregnancy after counseling ,the other 2 cases also induced labor due to intrauterine fetal death at 15+2 weeks and 19+2 weeks respectively . All 4 cases were confirmed as amniotic band syndrome by pathology . Conclusions When the fetal sonographic images showed fixed head position ,disordered intracranial structure ,or adhesion between umbilical cord and hand with limited movement at 11 -14 weeks′ gestation ,it should be paid attention to observing the band‐like echoes and followed up closely to prevent missed diagnosis of amniotic band syndrome .
