A hypertensive pregnant woman at 34 weeks comes with history of pain in abdomen, bleeding per vaginum and loss of fetal movements. On examination the uterus is contracted with increased uterine tone. Fetal heart sounds are absent. The most likely diagnosis is:
## **Core Concept**
The clinical presentation described points towards a severe obstetric complication involving hypertension, abdominal pain, vaginal bleeding, and loss of fetal movements. These symptoms, combined with a contracted uterus and increased uterine tone, are highly suggestive of a condition known as placental abruption. **Placental abruption** is a condition where the placenta separates prematurely from the uterus, leading to maternal bleeding, uterine contractions, and potential fetal distress or demise.
## **Why the Correct Answer is Right**
The correct answer, **placental abruption**, fits the clinical scenario provided. The condition is characterized by:
- **Hypertension**: Often associated with preeclampsia, which can lead to placental abruption.
- **Abdominal pain**: Caused by uterine contractions and possibly the abruption itself.
- **Vaginal bleeding**: Results from the disruption of maternal vessels at the placental site.
- **Loss of fetal movements and absent fetal heart sounds**: Indicate fetal demise, a possible consequence of severe placental abruption due to compromised placental function.
- **Increased uterine tone**: The uterus becomes hard and tender due to sustained contractions.
## **Why Each Wrong Option is Incorrect**
- **Option A (Placenta previa)**: While placenta previa can cause vaginal bleeding, it typically does not cause abdominal pain or increased uterine tone. Bleeding in previa is usually painless.
- **Option B (Uterine rupture)**: This condition would also present with severe abdominal pain and possibly hemodynamic instability, but the primary symptom would be a sudden, severe pain and possibly a change in the shape of the abdomen. Vaginal bleeding might not be a primary feature.
- **Option C (Preeclampsia without severe features)**: Preeclampsia can cause hypertension and proteinuria but does not directly cause vaginal bleeding, abdominal pain to this extent, or loss of fetal movements without other signs of severe disease.
## **Clinical Pearl / High-Yield Fact**
A key clinical pearl is that **placental abruption is often associated with preeclampsia**, and the presence of hypertension in pregnancy should raise the suspicion for this condition when abdominal pain and vaginal bleeding occur. The diagnosis is primarily clinical, supported by ultrasound findings.
## **Correct Answer:** . **Placental Abruption**
