The amniotic band syndrome (ABS) is a relatively rare entity with an estimated incidence of 1 in 1200 to 15000 livebirths. Strangulation of the umbilical cord can also occur in ABS. While it is assumed that umbilical cord is involved in 10% of cases, severe perinatal morbidity or mortality is rarely reported due to strangulation of the umbilical cord. Here, we report a case of umbilical cord strangulation causing still birth at term without preceding abnormalities in fetal well being tests. The fetus exhibited normal growth and had normal modified biophysical profile. The patient did not report decreased fetal movement except for the day of admission. In the post-mortem examination, we observed that there was no well established constriction ring or edema distal to the point of strangulation. The present case shows that umbilical cord involvement in ABS may lead to fetal death at term without antecedent signs.
