Bleeding by fibrinolysis In some injuries (for example, severe fractures), blood clots (clots) form in damaged vessels. A bruise usually occurs at the site of the blood clot. In addition, as a result of fibrin activity (blood dilution), it becomes possible to release a so-called fibrin blood clot. This leads to exposure of the walls of the damaged vessel, through which blood will subsequently be released. If they are not aligned correctly, pressure may occur around bone fragments or after removal of foreign bodies. In this case, bruises or hemorrhages form, and vascular thrombosis becomes more dangerous, since a disruption in the flow of oxygen and, as a result, tissue necrosis (death) easily occurs. Blood clots can take a long time to clear. If we are talking about large blood vessels, then it is unlikely to eliminate the blood clot; to prevent the development of complications, they resort to surgery. Blood clots can have fatal consequences
