Pulmonary Embolism information from trusted sources:
A pulmonary embolism (PE) is a blood clot in the lung. It usually comes from smaller vessels in the leg, pelvis, arms, or heart. When a clot forms in the legs or arms, it is referred to as a deep venous thrombosis (DVT). The clot travels through the vessels of the lung continuing to reach smaller vessels until it becomes wedged in a vessel that is too small to allow it to continue farther. The clot gets wedged and prevents any further blood from traveling to that section of the lung.
Blood Clots in the Lung
A pulmonary embolism is a sudden blockage in a lung artery. The cause is usually a blood clot in the leg called a deep vein thrombosis that breaks loose and travels through the bloodstream to the lung. Pulmonary embolism is a serious condition that can cause If a clot is large, or if there are many clots, pulmonary embolism can cause death.
Pulmonary embolism is a condition that occurs when one or more arteries in your lungs become blocked. In most cases, pulmonary embolism is caused by blood clots that travel to your lungs from another part of your body most commonly, your legs.
Pulmonary (PUL-mo-ner-ee) embolism (EM-boh-lizm) is the sudden blockage of an artery (blood vessel) in the lungs by an embolus. An embolus is usually a blood clot, but may also be fat, air, or tumor cells that are in the blood stream. With a pulmonary embolism, a blood clot may break loose from the blood vessels of the legs. The clot goes to the lungs where it plugs or blocks a blood vessel. The embolism can cut off the blood supply to that part of the lungs. Pulmonary embolism is a serious condition. Chances of survival are better with early diagnosis and treatment.
Phlebitis: the inflammation of a vein. Cause unknown. May occur in acute or chronic infections or following operations or childbirth. Embolism: the obstruction of a blood vessel by foreign substances or a blood clot. Diagnosis depends upon predisposing factors. Embolism usually due to blood clots. Thrombosis: the formation, development, or existence of a blood clot or thrombus within the vascular system. This is a life-saving process when it occurs during hemorrhage. It is a life-threatening event when it occurs at any other time because the clot can occlude a vessel and stop the blood supply to an organ or a part. The thrombus, if detached, becomes an embolus and occludes a vessel at a distance from the original site, for example a clot in the leg may break off and cause a pulmonary (lung) embolus. Consult the doctor immediately.
