Abstract
|
|
|
|
Amniotic band syndrome (ABS) is entrapment of fetal parts by disrupted amnion and formation of fi brous amniotic band. As results, it causes a variety of fetal malformation involving the limbs, the craniofacial region and trunk. A visualization of free floating amniotic band is appropriate diagnostic method for ABS. Three dimensional (3D) and four dimensional (4D) ultrasounds are useful to diagnosis ABS. However prenatal diagnosis is diffi cult especially when they do not circulate a limb or cause single abnormality. In the cases of anencephaly, a differentiation between ABS and primary neural tube defect is important because the recurrence rate is signifi cantly different. We reported a case that a fetal anencephaly with hydrops was diagnosed using prenatal 3D and 4D ultrasound then confi rmed as amniotic band syndrome by autopsy at 12 weeks of gestation. After autopsy, we demonstrated amniotic band through 3D ultrasound review.
