About

Placenta previa is usually diagnosed when the placenta implanted in the lower uterine segment, thus partially or totally overlying the internal os . It occurs with an incidence of 0.3-0.5%. It is associated mainly with prior caesarean delivery . The condition is frequently complicated by invasion of placental villi beyond the decidua basalis causing placenta accreta . Placenta previa is a major cause of massive haemorrhage during pregnancy and after delivery . The antepartum bleeding from placenta previa- can be life-threatening, thus, the prediction of this bleeding is of great importance . It is important to distinguish between women at high and low risk for antepartum haemorrhage with placenta previa especially at late pregnancy . However, the potential risk factors for antepartum haemorrhage in women with placenta previa have not been thoroughly examined.
