What complication is associated with deep vein thrombosis, particularly in older adults?

Deep vein thrombosis (DVT) occurs when a blood clot forms in a deep vein, often in the legs. One of the most serious complications associated with DVT, especially in older adults, is pulmonary embolism (PE). This occurs when a portion of the clot breaks free and travels through the bloodstream to the lungs, where it can block a pulmonary artery. The severity of a pulmonary embolism can vary, but it can lead to significant morbidity and mortality if not promptly recognized and treated.

Older adults are particularly at risk for DVT and subsequent pulmonary embolism due to factors such as decreased mobility, comorbidities, and changes in coagulation as they age. Recognizing this complication is vital in clinical practice, as early intervention can prevent the life-threatening consequences of PE.

The other options listed do not directly result from DVT. While cerebral vascular accidents and strokes can be serious conditions, they are primarily caused by issues related to blood flow in the brain rather than clots originating from deep veins. Aortic dissection involves a tear in the aorta, a completely different pathology that is not a complication of DVT. Therefore, pulmonary embolism is the complication most closely associated with deep vein thrombosis that presents significant concern in older
