In placenta pre conservative treatment is not done in case of :
**Core Concept**
Placenta previa is a condition where the placenta partially or completely covers the internal cervical os, posing a risk of severe bleeding during pregnancy and childbirth. Conservative management aims to manage symptoms and prevent complications until delivery.
**Why the Correct Answer is Right**
In cases of placenta previa, conservative treatment is not recommended if there is significant bleeding, which is often defined as more than 500-1000 mL of blood loss. This is because the risk of further bleeding and maternal hemodynamic instability outweighs the benefits of conservative management. In such cases, delivery by cesarean section is typically planned as soon as possible to prevent further complications.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is likely incorrect because significant bleeding is a common indication for delivery in cases of placenta previa.
**Option B:** This option is likely incorrect because there is no clear indication for conservative management in cases of placenta accreta spectrum disorders, which are often associated with placenta previa.
**Option C:** This option is likely incorrect because there is no clear indication for conservative management in cases of placenta previa with significant fetal growth restriction.
**Clinical Pearl / High-Yield Fact**
In cases of placenta previa, the risk of bleeding increases with gestational age, making timely delivery a priority. A key clinical correlation is that women with placenta previa are at increased risk of developing antepartum hemorrhage, which is often characterized by painless and painfull vaginal bleeding.
**Correct Answer: A. Significant bleeding.
