25 years old died just after child birth. On autopsy, hair, fat and epithelial cells were found in pulmonary vessel. Probable cause of death is:
## **Core Concept**
The question involves a postpartum death with autopsy findings of hair, fat, and epithelial cells in a pulmonary vessel. This scenario suggests a condition known as **amniotic fluid embolism (AFE)**, a rare but severe complication that can occur during childbirth.
## **Why the Correct Answer is Right**
Amniotic fluid embolism occurs when amniotic fluid or fetal material (such as hair, fat, or epithelial cells) enters the maternal circulation and triggers a severe reaction, often leading to cardiovascular collapse. The presence of hair, fat, and epithelial cells in the pulmonary vessel is highly suggestive of AFE. This condition can cause sudden maternal death due to obstruction of blood flow and initiation of a coagulopathy.
## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is not provided, but typically, incorrect options might include conditions like pulmonary thromboembolism, air embolism, or other causes of maternal mortality that do not specifically involve fetal material in the maternal circulation.
- **Option B:** Similarly, without the specific details of Option B, it's hard to address directly, but any option not involving the characteristic findings of AFE would be incorrect.
- **Option C:** Again, without specifics, but if it doesn't align with AFE or another directly related condition, it would be incorrect.
- **Option D:** This option is presumably incorrect as the correct answer is given as another option.
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that **amniotic fluid embolism** is a leading cause of maternal mortality worldwide and is often unpredictable. Clinicians must be vigilant for signs of AFE, such as sudden hypotension, hypoxia, and coagulopathy during or immediately after delivery. Early recognition and supportive care are critical.
## **Correct Answer Line**
**Correct Answer: B.**
