What condition is often caused by a blood clot fragment from the leg?

A clot fragment that breaks off from a deep vein in the leg can travel through the bloodstream to the lungs and block a pulmonary artery. This is called a pulmonary embolism, so the correct choice is pulmonary embolism. Hypertension is high blood pressure, while dysrhythmia is an abnormal heart rhythm; neither is the condition typically caused by a traveling leg clot.
