What is the most feared consequence of deep vein thrombosis?

The most feared consequence of deep vein thrombosis (DVT) is pulmonary embolism. This occurs when a blood clot, which typically forms in the deep veins of the legs, breaks loose and travels through the bloodstream to the lungs. Once in the lungs, the clot can block a pulmonary artery, significantly impeding blood flow and leading to severe complications, including difficulty breathing, chest pain, and potentially death.

The risk of pulmonary embolism is a critical concern because it can develop unexpectedly and rapidly, posing a life-threatening situation. The prevention and management of DVT are crucial in the perioperative setting, as surgical patients are particularly susceptible due to factors such as immobility and vascular changes during and after surgery. Therefore, understanding and addressing the risk of pulmonary embolism is vital for improving patient outcomes in those affected by DVT.
