Acute pulmonary embolism is an acute blockage of the pulmonary artery caused by a blood clot traveling from the deep veins of the legs to the lungs, leading to pulmonary embolism which can be life-threatening. However, if diagnosed and treated promptly, the risk of death can be significantly reduced.

Acute pulmonary embolism occurs when an artery in the lungs is blocked by a blood clot. Symptoms of acute pulmonary embolism often occur suddenly and are dangerous. Therefore, patients need to be detected and treated promptly.

Pulmonary embolism is one of the three leading causes of cardiovascular death. Compartment syndrome is a rare complication that can occur in the treatment of pulmonary embolism with thrombolytic therapy.
