The most common cause of cerebral thrombosis is arteriosclerosis. Because of cerebral arteriosclerosis, the lumen intima is rough, and the lumen is narrow, under certain conditions, such as reduced blood pressure, slow blood flow, or increased blood viscosity, enhanced platelet aggregation and other factors, coagulation factors agglomerate in the lumen to form thrombus, occlude blood vessels, and interrupt blood flow, Thus, the cerebral tissue in the blood supply area of the blood vessel will suffer from ischemia, hypoxia, softening and necrosis. Cerebral thrombosis can occur in any part of the cerebral artery, but in clinical practice, it is the most common thrombosis formed by the branches of the internal carotid artery, the anterior cerebral artery and the middle cerebral artery.
