Placenta Previa; Review Article

Abstract

In placenta previa, the placenta totally or partially covers the internal os of the cervix. It forms a major risk factor for postpartum hemorrhage and can lead to morbidity and mortality of the mother and newborn. Given the situation, it is necessary to deliver the baby via caesarean section to ensure its safety. Even though most cases are diagnosed with sonography, some pregnant women may present to the emergency hospital in the second or third trimester with painless vaginal bleeding. In the presence of placenta previa, a woman's risk of having placenta accreta spectrum may also increase (PAS).This spectrum of conditions include placenta accreta, increta, and percreta. Uncontrolled postpartum hemorrhage caused by placenta previa or PAS may necessitate blood transfusions, hysterectomy leading to infertility, or intensive care unit admission (ICU), or possibly lead to death.
