Normally, the placenta grows onto the upper part of the uterus and stays there until your baby is born. During the last stage of labor , the placenta separates from the wall of the uterus, and your contractions help push it into the vagina birth canal. This is also called the afterbirth. Sometimes the placenta attaches itself into the wall of the uterus too deeply. This can cause problems, including: Placenta accreta — The placenta attaches itself too deeply and too firmly into the uterus.
Placenta increta — The placenta attaches itself even more deeply into the muscle wall of uterus. Placenta percreta — The placenta attaches itself and grows through the uterus, sometimes extending to nearby organs, such as the bladder. This can cause dangerous bleeding. These conditions happen in about 1 in births each year. What are the signs of these placental conditions? Placental conditions often cause vaginal bleeding in the third trimester.
Call your health care provider right away if you have vaginal bleeding anytime during your pregnancy. If the bleeding is severe, go to the hospital right way. How are these placental conditions diagnosed? These conditions usually are diagnosed using ultrasound.
In some cases, your provider may use magnetic resonance imaging MRI. MRI is a medical test that makes a detailed picture of the inside of your body.
The test is painless and safe for you and your baby. How are these placental conditions treated? When these conditions are found before birth, your provider may recommend a cesarean section also called c-section immediately followed by a hysterectomy.
This can help prevent bleeding from becoming life threatening. A c-section is surgery in which your baby is born through a cut that your provider makes in your belly and uterus. A hysterectomy is when your uterus is removed by surgery. If you have a placental condition, the best time for you to have your baby is unknown.
But your provider may recommend that you give birth at around 34 to 38 weeks of pregnancy to help prevent dangerous bleeding. If you want to have future pregnancies, she may use special treatments before the c-section to try to control bleeding and save your uterus. If your provider finds these conditions at birth, she may try to remove the placenta in surgery to stop the bleeding. However, a hysterectomy is often necessary. What causes these placental conditions? But they often happen where you have a scar from a surgery, like removing a fibroid or having a c-section.
A fibroid is a tumor that grows in the wall of the uterus womb. Things that may make you more likely to have these kinds of placental conditions include:.
