Placenta accreta

Placenta accreta is a serious pregnancy complication that occurs when the placenta grows too deeply into the uterine wall. Typically, the placenta detaches from the uterine wall after childbirth. However, in cases of placenta accreta, part or all of the placenta remains attached. This can cause severe blood loss after delivery. It is a life-threatening condition that requires immediate medical attention.

Causes

The exact cause of placenta accreta is unknown. However, it is more common in women who have had a previous Cesarean section or other uterine surgery. Other risk factors include being older than 35 and having multiple previous pregnancies.

Symptoms

Placenta accreta often does not cause any symptoms. However, it can sometimes cause vaginal bleeding in the third trimester of pregnancy.

Diagnosis

Placenta accreta is usually diagnosed through an ultrasound during pregnancy. If the ultrasound results are unclear, an MRI may be used.

Treatment

The primary treatment for placenta accreta is surgical removal of the placenta and any affected parts of the uterus. This is often done through a procedure called a hysterectomy. In some cases, blood transfusions may be needed.

Prognosis

With prompt treatment, most women with placenta accreta can go on to have healthy pregnancies in the future. However, the condition does increase the risk of complications in future pregnancies, including preterm birth and low birth weight.
