A possible complication of untreated deep vein thrombosis (DVT) is pulmonary embolism. This occurs when a blood clot, typically formed in the deep veins of the legs, dislodges and travels to the lungs, blocking a pulmonary artery. This condition can be life-threatening and is one of the most serious complications associated with DVT.

When a DVT goes untreated, the risk of the clot breaking off increases significantly. If the clot reaches the heart, it can then travel to the lungs, which is where pulmonary embolism occurs. Symptoms may include shortness of breath, chest pain, and coughing up blood. Immediate medical intervention is essential for managing this complication.

Other conditions, such as pneumonia, stroke, or heart failure, may arise from various health issues but are not direct complications of untreated DVT. Understanding the direct relationship between DVT and pulmonary embolism is crucial for recognizing the potential dangers of not treating a DVT promptly.
