Introduction

Placenta previa is one of the leading cause of maternal morbidity and contributes to perinatal mortality.^[1] It is defined as a condition where the placenta is implanted in lower uterine segment, partially or totally covering the cervical internal os. Complete placenta previa occurs when the placenta covers the internal os even after it is fully dilated. Its incidence ranges from 0.5-1% among hospital deliveries.

Intrauterine death is related to severe degree of separation of placenta with maternal hypovolemia and shock. It also occurs due to acute placental insufficiency. The fetal deaths related to placental causes accounts for 20-35%.

Rh incompatibilty refers to discordant pairing of maternal and fetal Rh type. It is associated with the development of maternal Rh sensitization and hemolytic disease of neonate (HDFN). The incidence of the disease however is now on decline from 1.3-1.7% in 1980’s to 0.17% in 1990’s. The fetal death occurs due to cardiac failure.
