Placenta previa

Overview

Placenta previa is a condition that occurs during pregnancy when the placenta attaches to the lower part of the uterus, covering the cervix. This can cause severe bleeding in the mother before, during, or after delivery.

Types of Placenta previa

There are several types of placenta previa:

1. Partial Placenta Previa: The placenta partially covers the cervix.
2. Complete Placenta Previa: The placenta completely covers the cervix.
3. Marginal Placenta Previa: The placenta is attached to the edge of the cervix.

Causes of Placenta previa

The exact cause of placenta previa is not known, but it is believed to be related to:

1. Previous C-Section or Cesarean Delivery: Women who have had a previous C-section or cesarean delivery are at increased risk of developing placenta previa.
2. Uterine Scarring: Women who have had uterine surgery or trauma may be at increased risk.
3. Multiple Pregnancies: Women who are carrying multiple fetuses may be at increased risk.

Risk Factors of Placenta previa

The following risk factors may increase the likelihood of developing placenta previa:

1. Previous Pregnancy Complications: Women who have experienced complications during previous pregnancies may be at increased risk.
2. Age: Women over 35 years old may be at increased risk.
3. Family History: Women with a family history of placenta previa may be at increased risk.

Symptoms of Placenta previa

Preventions of Placenta previa

There is no known way to prevent placenta previa, but early detection and treatment can help manage the condition and reduce the risk of complications.

Diagnosis of Placenta previa

Diagnosis and evaluation of placenta previa typically involve:

1. Ultrasound: Ultrasound imaging to visualize the placenta and uterine wall.
2. Magnetic Resonance Imaging (MRI): MRI imaging to further evaluate the extent of placental invasion.
3. Blood Tests: Blood tests to monitor for signs of infection or blood loss.

Treatment for Placenta previa

Treatment and management of placenta previa depend on the severity of the condition:

1. Conservative Management: Conservative management may involve monitoring blood loss and administering medications to control bleeding.
2. Surgical Management: Surgical management may involve removing the placenta and uterus or performing a hysterectomy.
