Placenta Issues: Is Active Placenta the Same as Placenta Previa?

Production issues

Hello, doctor.
I would like to ask if the term "living placenta" during delivery refers to placenta previa? Will this living placenta condition be detectable during prenatal check-ups and high-level ultrasound examinations?

Dr. Cao Guotao reply Obstetrics and Gynecology

Hello, I am unclear about what is meant by "live placenta." In Western medicine, there is only the term "placenta previa," which can be identified during prenatal examinations using ultrasound to determine if there is an issue.
Wishing you good health.

More Info

The terms "active placenta" and "placenta previa" are often misunderstood, and it's essential to clarify their meanings and implications for pregnancy and delivery.
Placenta Previa refers to a condition where the placenta is abnormally positioned in the lower part of the uterus, covering or being very close to the cervix. This can lead to complications during delivery, such as severe bleeding, which can pose risks to both the mother and the baby. Depending on the degree of coverage, placenta previa can be classified into several types: complete, partial, marginal, or low-lying.
On the other hand, the term "active placenta" is not a standard medical term. It may refer to a placenta that is functioning normally, meaning it is adequately providing nutrients and oxygen to the fetus. However, it is crucial to note that this term is not commonly used in medical literature or practice.
During routine prenatal care, including high-resolution ultrasounds, healthcare providers can assess the position of the placenta. Typically, a detailed ultrasound is performed around 18-20 weeks of gestation, where the placenta's location can be evaluated. If the placenta is found to be low-lying or covering the cervix, further monitoring will be necessary as the pregnancy progresses. In many cases, the placenta may move upward as the uterus expands, resolving the previa condition before delivery.

If a woman has been diagnosed with placenta previa, her healthcare provider will likely recommend specific precautions, such as avoiding strenuous activities or sexual intercourse, to minimize the risk of bleeding. The management of placenta previa often depends on the severity of the condition and the gestational age of the fetus. In cases of complete previa, a cesarean delivery is usually planned to ensure the safety of both mother and child.

In summary, while "active placenta" and "placenta previa" are not synonymous, understanding the health and positioning of the placenta is crucial during pregnancy. Regular prenatal check-ups and ultrasounds are vital for monitoring placental health and addressing any potential issues early on. If you have concerns about your placenta's position or function, it is essential to discuss them with your healthcare provider, who can provide personalized advice and care based on your specific situation.
