Patient's question:
What is the abortion rate with placenta previa? (Yesterday, the ultrasound showed that the placenta was low-lying, and the card indicated that the placenta was attached to the cervix. Is this considered placenta previa? Is this situation dangerous? What is the abortion rate?)Doctor's answer:
Hello:Placenta previa is a delivery complication where a part or all of the placenta covering the cervix blocks the birth canal. This condition can now be detected early through ultrasound examinations. If a woman has placenta previa, she may bleed as early as the 24th week of pregnancy or during the onset of labor. If the bleeding is severe, an obstetrician may recommend a cesarean delivery, even if the fetus is not yet full-term. If the bleeding is less severe, the pregnant woman may stabilize her blood volume through blood transfusions. If only part of the birth canal is blocked, the obstetrician will advise the woman to be admitted to the hospital, rest in bed, and wait until the fetus is more mature before moving the placenta to one side to allow the fetus to pass through the birth canal. Some women are more prone to developing placenta previa, especially those who have undergone cesarean sections, had uterine fibroids, or other uterine conditions.
Another pregnancy complication related to the placenta is called premature placental abruption. This occurs when the placenta partially or completely detaches from the uterine wall before the baby is born. If this happens, an emergency cesarean delivery must be performed to save the fetus. If the fetus has died, it must also be removed as quickly as possible to prevent excessive bleeding in the pregnant woman.
