[0004] Cerebral infarction is roughly classified into cerebral thrombosis and cerebral embolism according to the pathogenic mechanism. Cerebral thrombosis is a cerebral infarction caused by thrombosis in the cerebral perfusion arteries including the carotid artery. The presence of vascular lesions, changes in blood properties, and hemodynamic fluctuations are involved in thrombus formation, and the presence of vascular lesions is the most important.

Atherosclerosis is the most common vascular lesion in the main coronary arteries of cortical branches, and vascular necrosis associated with hypertension is highly involved in perforating branches. Therefore, hypertension, diabetes, etc. are emphasized as risk factors for cerebral thrombosis. In addition, vasculitis, vascular malformation, etc. may be a factor in thrombus formation. Changes in blood characteristics include abnormalities such as dehydration, polycythemia, and thrombocytosis that increase blood viscosity and hypercoagulability. Further, when hemodynamic factors such as a decrease in perfusion pressure are added, thrombus formation is promoted.
