Abstract

Amniotic band syndrome is a congenital disorder caused by entrapment of fetal parts (usually a limb or digits) in fibrous amniotic bands while in utero. Amniotic constriction bands are strands of fluid-filled sacs that surround a baby in the womb. They are caused by a tearing of the inner part of the placenta called the amnion, which produces the fiber-like bands that may trap the baby’s extremities such as the arms, legs, fingers or toes. As the baby grows, the bands constrict or tighten, they cause a reduction in blood supply and they may develop abnormally or become amputated. In more serious cases, the band may cause an abnormal gap in the face, called a cleft, or cause a defect in the abdomen or chest wall. The most severe cases occur if the band becomes wrapped around the head or umbilical cord, which can result in fetal death.
