CIRCUMVALLATE PLACENTA COMPLICATING TO PRETERM PREMATURE RUPTURE OF MEMBRANES: A CASE REPORT
Circumvallate placenta, a morphological abnormality of placenta can be defined as a thickened placenta with a raised margin in an annular shape and it is thought to be the result of a membranous fold of chorion and amnion. A 23-year-old primigravida mother was presented with grossly reduced liquor due to preterm premature rupture of membranes at 32 weeks of gestation. The preterm baby was delivered by emergency caesarean section (category-2 caesarean section). A thorough gross examination of the placenta was done and a thickened circumvallate placenta was noted with a firm white annular margin and normal umbilical cord insertion. Histopathological findings were consistent with the diagnosis of circumvallate placenta. Routine gross examination of placenta is of immense important for better understanding of pregnancy complications due to placental abnormalities like circumvallate placenta.
