Embolism - Definition


An embolism is a sudden interruption of a liquid circulating in the body, blood or lymph, by a foreign body. An embolism causes obstructions in the vascular network which result in a decrease in, or complete lack of, oxygenation of the tissues: it is a common contributor to stroke, myocardial infarction, or acute limb ischemia. The substance causing the obstruction may be a blood clot, cholesterol crystals, gas, or fatty masses ... The risks of embolism are higher in cases of smoking, high cholesterol, heart disease, including cardiac arrhythmia by atrial fibrillation (CA / AF), or hypertension. One of the most serious embolisms is the pulmonary embolism, where a blood clot from the leg veins frequently migrates and closes off a pulmonary artery. The use of anticoagulants is necessary in this type of embolism.
