It is relatively unusual (25% of the total number of cases) for<unk>  emboli to occur spontaneously; this usually happens in people with severe atherosclerosis of the large arteries such as the aorta. In the other 75% it is a complication of medical procedures involving the blood vessels, such as vascular surgery or angiography. In coronary catheterization, for instance, the incidence is 1.4%. Furthermore,<unk>  may develop after the commencement of anticoagulants or thrombolytic medication that decrease blood clotting or dissolve blood clots, respectively. They probably lead to<unk>  emboli by removing blood clots that cover up a damaged atherosclerotic plaque;<unk> -rich debris can then enter the bloodstream.
