Organized Thrombus may become re-canalize (capillary channels are formed in the organized ; Center of thrombus may undergo enzymatic digestion and softens due to release of lysosomal enzymes from the trapped leukocytes and platelets, such soften debris is ideal culture medium for bacterial growth. ISCHEMIC INJURY : Thrombi may decrease or stop the blood supply to part of an organ or tissue and cause ischemia which may be subsequently result in infarction. This is a key reason for the continued high mortality and morbidity in these conditions, despite endovascular reperfusion treatments and continuous efforts to improve timeliness and access to these treatments. Mechanical clot retrieval and catheter-guided thrombolysis are used in certain situations. accumulate more platelets and fibrin enlarged -> vessel obstruction. 6. Created by.
