never heard of it but just found this x

As the baby develops, its extremeties may become entangled resulting in immobilisation, trapping, constriction or even amputation. It really isn't known if the reports of limb reductions associated with early CVS are due to amniotic bands. On ultrasound the bands appear as thin, mobile lines, which may be seen attached to or around the baby. About 70% of amniotic bands disappear on follow-up ultrasound, presumably due to rupture or compression.

If there is no evidence of any abnormality, other than the amniotic band, at the time of the scan then there appears to be little risk to the baby. Other reassuring factors are normal fetal movement and the band not being attached to the baby. In this case they have been called 'innocent amniotic bands'.
One study has looked at 25 cases of innocent amniotic bands and found a 4-fold increased risk of preterm delivery (before 37 weeks) and a 9-fold increased risk of a low birth weight infant. The numbers in this study were small and this is something that needs a larger study to confirm or refute.
