Question

What is the next line of management for a 25 year old woman who develops acute pulmonary embolism?

• A. Thrombolysis
• B. LMW heparin
• C. Oral anticoagulants
• D. IVC filter

Hint:

A life threatening PE needs clot dissolving therapy, not just clot prevention.

Answer 1

The Correct Option is A

This question is testing the treatment ladder for acute pulmonary embolism (PE) and which step comes first when the embolism is severe enough to demand urgent action.

1. Thrombolysis: Drugs such as streptokinase or alteplase break down the clot itself within hours. This is reserved for a large or massive PE, where the clot burden threatens the patient's life and there is no time to wait for anticoagulation alone to work.
2. LMW heparin: This stops the clot from growing bigger and stops new clots forming, but it cannot dissolve the clot already blocking the pulmonary artery. It is the right choice for a stable patient, not a critical one.
3. Oral anticoagulants: Warfarin and similar drugs take several days to become fully effective, so they are used later for long term prevention, never as an emergency first step.
4. IVC filter: This device sits in the inferior vena cava and traps future clots travelling up from the legs. It protects against a future embolism but does nothing to the clot already present in the lungs.

The correct next step is thrombolysis, because breaking down the existing clot fast is what a severe, life threatening pulmonary embolism needs.

Let's summarize:

• Thrombolysis dissolves the clot and is used for high risk, unstable PE.
• LMW heparin and oral anticoagulants only prevent new clot, they do not clear the existing one.
• An IVC filter only prevents future emboli, it has no effect on a clot already in the lung.

So the immediate next line of management here is thrombolysis.
