Pulmonary embolism (PE) is a blood clot in an artery of the lungs. The most common place for the clot to travel from is a vein in the legs. Most of the time this is due to some type of trauma to the legs, like a broken bone. However the clot could also come from a vein in the pelvis, the arm, the shoulder, or even the heart. Blood clotting problems can also cause blood clots to form in the lungs.
Some people do not have any symptoms. Other people will breathe faster, feel chest discomfort, and/or be more short of breath. A radiology test called a ventilation perfusion (VQ) scan, like you had done, is most commonly used to identify the problem. Sometimes pulmonary arteriography is used.
Generally blood clots are treated with Coumadin
Thank you for the information. Does this mean even though I am on 7.5mg of Warafin daily that the clots COULD still develop even though the genetic testing was negative??
