Placenta Accreta: Causes, Symptoms and Treatment

The placenta accreta is a condition where the placenta attaches too deeply into the uterine wall, leading to potential complications during childbirth. It occurs when the blood vessels and other parts of the placenta grow too far into the uterine wall, making it difficult for the placenta to detach after delivery. The exact cause of placenta accreta is not fully understood, but it is commonly associated with previous uterine surgeries, such as cesarean sections, which can leave scar tissue behind.

Other risk factors may include advanced maternal age, previous placenta previa, or multiple pregnancies. Understanding the causes of placenta accreta is crucial for early detection and appropriate management to ensure the best possible outcome for both the mother and the baby.

Symptoms of Placenta Accreta

Placenta accreta can cause various symptoms during pregnancy or childbirth, such as vaginal bleeding that doesn't stop, severe abdominal pain, and an inability to deliver the placenta after giving birth. You may also experience a rapid heartbeat, low blood pressure, or signs of shock.

In some cases, placenta accreta can be detected before delivery through ultrasound. If you notice any of these symptoms, it's essential to seek immediate medical attention to ensure a safe delivery and prevent complications.

Causes of Placenta Accreta

The main factors contributing to placenta accreta include previous cesarean sections, advanced maternal age, and uterine scarring from prior surgeries or procedures. Other risk factors such as multiple pregnancies, a history of placenta previa, and conditions like endometrial damage or fibroids can also increase the likelihood of developing placenta accreta. These factors disrupt the normal development of the placenta, leading to its abnormal attachment and potential complications during childbirth.

Types Of Placenta Accreta

Accreta occurs when the placenta attaches too deeply into the uterine wall, while increta involves a deeper invasion where the placenta penetrates the uterine muscle. Percreta is the most severe form, where the placenta penetrates through the uterus and can even reach nearby organs. These conditions can lead to significant complications during pregnancy and delivery, requiring careful management and often necessitating a cesarean hysterectomy to prevent life-threatening bleeding.

Risk Factors

Several risk factors increase the likelihood of developing placenta accreta, including previous cesarean sections, advanced maternal age, multiple pregnancies, and a history of placenta previa. Other factors such as uterine scarring from previous surgeries, smoking, and infertility treatments also contribute to the risk. Early identification and proactive management are crucial in preventing complications associated with placenta accreta during pregnancy and childbirth.

Diagnosis of Placenta Accreta

Ultrasound is often the initial diagnostic tool, revealing abnormalities in the placental attachment. Magnetic resonance imaging (MRI) can provide more detailed information about the extent of placental invasion. During surgery, the presence of difficulties in separating the placenta from the uterine wall can further confirm the diagnosis. A multidisciplinary team of healthcare providers, including obstetricians, radiologists, and surgeons, collaborates to accurately diagnose and manage placenta accreta.

Treatment for Placenta Accreta

Placenta accreta, a serious pregnancy complication where the placenta attaches too deeply into the uterine wall, often requires a multidisciplinary approach for treatment. Management typically involves a combination of surgical and medical interventions tailored to each individual case. In some instances, a cesarean hysterectomy might be necessary to remove the placenta and control bleeding.

Other options include conservative management techniques such as uterine artery embolization or methotrexate therapy to help preserve fertility. Close monitoring by a team of obstetricians, maternal-fetal medicine specialists, and sometimes interventional radiologists is crucial to ensure the best possible outcome for both mother and baby.

In cases of mild placenta accreta, close monitoring during pregnancy with regular ultrasounds and blood tests to assess the placental attachment may be sufficient. In more severe cases, where there is a high risk of significant bleeding during delivery, a planned cesarean section with a surgical team experienced in managing placenta accreta may be recommended.
