Favourable outcome of a tight constriction band secondary to amniotic band syndrome.

Amniotic band syndrome or amniotic disruption complex is a well-known congenital limb abnormality, which occurs in 1 in 1200 to 1 in 15,000 live births. In cases of an isolated band constriction, it has been speculated that the bands lead to decreased blood flow in the constricted limb and subsequent natural amputation. Fetal surgery could be considered in these situations in order to release the constriction band in threatened limb amputation. We present a case of a tight constriction ring secondary to amniotic band syndrome with a favourable outcome, despite the failure of an attempted surgical procedure.
