Understanding Placenta Accreta: Effects on Pregnancy

Pregnancy is often viewed as a journey guided by medical knowledge and generational wisdom, yet the reality can be quite unpredictable. Despite following every guideline and expert recommendation, many factors influencing pregnancy outcomes remain a mystery. It’s essential to recognize that unexpected situations can arise, and it’s crucial not to place blame on the pregnant individual if complications occur. If you or someone you know has been diagnosed with placenta accreta, this article will provide insights into its symptoms, potential risks, treatment options, and management strategies.

What is Placenta Accreta?

Placenta accreta is a condition in which the placenta attaches too deeply into the uterine wall. According to research from reputable medical institutions, this condition can lead to serious complications, such as difficulty delivering the placenta after childbirth and excessive bleeding during its removal. Generally, there are no noticeable symptoms during pregnancy, but vaginal bleeding in the third trimester may indicate the condition.

Causes of Placenta Accreta

While researchers have not identified a singular cause for placenta accreta, it often occurs in individuals with uterine lining abnormalities, usually due to scarring from previous surgeries like C-sections. However, not all cases of placenta accreta are linked to such scarring. Other contributing factors include:

Placenta Position: If the placenta is positioned low in the uterus or covers the cervix, the risk increases.
Maternal Age: Women over 35 are at a higher risk.
Previous Pregnancies: The likelihood of developing the condition increases with each successive pregnancy.

Types of Placenta Accreta

There are two other related forms of this condition, categorized by how deeply the placenta invades the uterine wall:

Placenta Increta: The placenta grows into the uterine wall but does not penetrate through it.
Placenta Percreta: This severe form involves the placenta growing through the uterine wall and potentially affecting surrounding organs.

Diagnosis and Detection

Placenta accreta may sometimes be detected during routine ultrasounds, but it is often diagnosed just before or during delivery. If suspected during pregnancy, ultrasound imaging is typically used, while MRI can be a supplementary tool when necessary. Early diagnosis can help manage the condition effectively, but many individuals can still experience a standard delivery.

Treatment Approaches

Treatment for placenta accreta largely depends on the severity of the condition and when it is diagnosed. In many cases, surgery is required, which could involve the complete or partial removal of the placenta. Techniques include:

Cord Traction: This method helps deliver the placenta with less blood loss, making it a preferred choice.
Manual Removal: A doctor may directly extract the placenta from the uterine wall, which is a more invasive approach.

In cases where the condition is diagnosed early and is severe, healthcare providers may recommend scheduling a C-section followed by a hysterectomy to minimize the risk of life-threatening hemorrhage. If a hysterectomy is performed, the ovaries are usually preserved to avoid premature menopause.

Risks of Retained Placenta

It is vital to remove the placenta after delivery. If left inside, it can prevent the uterus from closing, leading to significant hemorrhaging. The placenta should ideally be delivered within 30 minutes post-birth; otherwise, complications may arise, including severe bleeding, the need for blood transfusions, or even hysterectomy.
