Amniotic bands associated with early rupture of amnion due to an intrauterine device.

Amniotic bands in consequence of early rupture of amnion-membrane was found in a spontaneously aborted gestational sac. This case seems to confirm the theory that amniotic bands develop due to amnion rupture principally caused by exogenous less frequently by endogenous factors. In the reported case the exogenous factor was an intrauterine device, the resulting inflammation presumably responsible for rupture of amnion.
