A cerebral infarction is a type of what the people call a cerebral thrombosis. Cerebral infarction is divided into blockage of emboli of arterial origin, as well as dislodgement of emboli of cardiac origin, and then small vascular lesions. Clinically, cerebral infarction is often divided into large cerebral infarction, watershed cerebral infarction, precortical cerebral infarction, postcortical cerebral infarction, subcortical cerebral infarction, cerebral bridge infarction, cerebellar infarction, and multiple cerebral infarction according to the location, volume and nature. Among them, multiple cerebral infarcts are infarcts caused by occlusion of 2 or more different blood supply systems and different cerebral vessels, and are commonly seen in patients with recurrent infarcts. In lacunar cerebral infarcts, most CTs show small hypointensities that will be in the basal ganglia, internal capsule, thalamus, brainstem, and subcortical white matter. Vascular cerebral infarcts, most of which are deep penetrating vessels, and this type of lacunar cerebral infarct is most often seen in patients with hypertension. Hemorrhagic infarction, which is necrosis of the arteries in the blood supply area of the cerebral infarct, leaks blood out and secondary hemorrhage occurs. All of these are grouped into what the people call cerebral thrombosis, so cerebral infarction is cerebral thrombosis.
