What percentage of patients with deep vein thrombosis (DVT) may develop pulmonary embolism?

The correct response indicates that 10-40% of patients with deep vein thrombosis (DVT) may develop pulmonary embolism (PE). This range reflects a clinically recognized risk associated with DVT, which occurs when a blood clot in a deep vein, usually in the legs, dislodges and travels to the lungs, causing an obstruction.

This risk percentage highlights the importance of monitoring for pulmonary embolism in patients diagnosed with DVT, as the condition can be life-threatening. Effective preventive measures, such as anticoagulation therapy or mechanical devices like compression stockings, are critical in managing patients at risk for DVT to help lessen the likelihood of developing a PE.

In contrast, the other options suggest either too low or too high a percentage, which does not align with established clinical evidence. Acknowledging the correct range is essential for both perioperative planning and patient education about the potential complications arising from DVT. Understanding this risk is crucial for healthcare professionals in identifying patients who may benefit from further intervention or monitoring.
