What is an embolism?
An embolism is a blockage in one of the arteries of the body due to a blood clot that has broken off from another location in the body (embolus) and traveled through the bloodstream to lodge in a small blood vessel. The blockage may limit or stop blood flow. An embolism may be serious and life threatening.
Blood Problems Spotlight
Deep vein thrombosis is the primary cause of embolism. In deep vein thrombosis, blood clots form in the large veins of the legs. Sometimes a blood clot breaks free and is carried through the bloodstream. It may then cause an embolism by blocking an artery in the lungs, brain, or other organs.
Symptoms of embolism vary greatly depending on the severity and location of the embolism. Some individuals with embolism have no symptoms. An embolism in the lungs is called a pulmonary embolism. An embolism in the brain can cause a stroke. An embolism in the coronary vessels that supply the heart can cause a heart attack.
Treatment of embolism aims to dissolve, remove, or limit the growth of the blood clot. This may be achieved through medication, minimally invasive procedures, or, rarely, surgery.
An embolism may be life threatening. Seek immediate medical care (call 911) for serious symptoms, such as altered vision, chest pain, fainting, palpitations, sweating, or severe difficulty breathing, or if you think you may be having a heart attack or stroke.
