What is amniotic band syndrome?

Amniotic band syndrome refers to birth defects that occur when amniotic bands in the womb get wrapped around parts of the fetus. Depending on what body part gets wrapped there can be different birth defects. Arms, legs, hands and feet are most commonly affected and can be deformed or even amputated. If a band wraps around the umbilical cord it can cause a miscarriage. Amniotic band syndrome is not inherited or caused by anything the mother did. It just occurs randomly, so there is no higher risk that a future pregnancy would be affected.
