Thrombosis

Formation of blood clots within the veins; blood coagulation, also intravital thrombus formation in the circulatory system. Predilection sites: Heart valves, ears (often spherical thrombus) and left apex, coronary vessels, basal brain vessels, arteria mesenterica (claudicatio abdominalis) and leg arteries as well as veins of the legs and pelvis, rectum (haemorrhoid thrombosis) and arm. Frequently postoperative (and postpartum), mostly on deep leg veins, possibly complicated by thrombemia (e.g. pulmonary embolism). If the tendency to thrombosis is increased, generalized (e.g. cardiac insufficiency, shock, bedriddenness, prolonged sitting still) or local (compression, inflammatory or atherosclerotic vascular alterations) treatment may be appropriate.
