As nouns the difference between thrombus and embolization

is that thrombus is (hematology|pathology) a blood clot formed from platelets and other elements; that forms in a blood vessel in a living organism, and causes thrombosis or obstruction of the vessel at its point of formation or travel to other areas of the body while embolization is (surgery) a nonsurgical, minimally invasive procedure that effects the selective occlusion of blood vessels by purposely introducing emboli.
