Final answer:
Women with previous uterine scars are prone to placenta previa, a condition that occurs if the embryo implants close to the cervix's inner opening, leading to potential complications such as antepartum and postpartum hemorrhage.
Step-by-step explanation:
Women with previous uterine scars are prone to placenta previa. Placenta previa is a condition that can result when an embryo implants too close to the internal os of the uterus, potentially leading to the placenta partially or completely covering the opening of the cervix as the fetus grows. This condition can cause antepartum hemorrhage, which is profuse vaginal bleeding after week 24 of pregnancy but prior to childbirth. It is crucial for an obstetrician to ensure that the expelled placenta and fetal membranes are intact to prevent postpartum hemorrhage.
