Newborn with amniotic band sequence

KEY CLINICAL MESSAGE: Amniotic band sequence (ABS) should be on the differential for newborns with limb defects. ABS is diagnosable prenatally with prenatal ultrasound; however, there are cases where the diagnosis of ABS is made only after delivery of the newborn. ABSTRACT: Amniotic band sequence (ABS) is an uncommon congenital disorder where strands of amniotic tissue cause entrapment of the limbs, body wall, and viscera leading to an array of congenital malformations. We report a case of a newborn with prenatally undiagnosed amniotic band sequence.
