A patient of left hemiplegia with previous history of right deep vein thrombosis. Cause of hemoptysis in this patient is?
**Core Concept**
The question involves a patient with left hemiplegia and a history of right deep vein thrombosis (DVT), presenting with hemoptysis. The underlying principle being tested is the association between **pulmonary embolism (PE)** and hemoptysis in a patient with a history of DVT.
**Why the Correct Answer is Right**
Hemoptysis in this patient could be due to **pulmonary infarction** secondary to a pulmonary embolism, which is a possible complication of DVT. The embolus can break loose, travel to the lungs, and cause an infarction, leading to hemoptysis.
**Why Each Wrong Option is Incorrect**
**Option A:** Not provided, but typically other options might include causes like pneumonia or bronchitis, which are less directly related to the patient's history of DVT.
**Option B:** Similarly, without the specific option, we can say that any option not considering the patient's DVT history and its potential for PE would be incorrect.
**Option C:** and **Option D:** would be incorrect for the same reason, lacking a direct connection to the patient's history of DVT and potential for PE.
**Clinical Pearl / High-Yield Fact**
A high-yield fact here is that patients with a history of DVT are at increased risk for **pulmonary embolism**, which can present with symptoms like hemoptysis, especially if there's an associated pulmonary infarction.
**Correct Answer:** Correct Answer: D. Pulmonary embolism.
