In the past as stated by Williams, circumvallate placenta was considered to be a mere interesting anatomic variation of placenta without any clinical significance (3).
Subsequently, other studies have also shown increased incidence of complications in patients with circumvallate placenta like abruptio placentae, preterm births, IUGR, oligohydramnios, non-reassuring foetal heart rate patterns (4, 5) and even a study reported increased incidence of IUFD as compared to controls (5).
The diagnosis of circumvallate placenta antenatally is however very difficult.
Both circumvallate placenta and Battledore insertion of the umbilical cord are rare and are known to adversely affect the pregnancy outcome individually and in these women, their coexistence leads to a more serious untoward consequence of IUFD.
