Common stroke and cerebral thrombosis introduced

According to various acute cerebrovascular disease etiology, pathology and the performance of stroke in general is divided into two categories : one category is hemorrhagic stroke, also known as hemorrhagic cerebrovascular disease, cerebral vascular refers to rupture. Bleeding including cerebral hemorrhage and subarachnoid hemorrhage. Another type of ischemic stroke, also called ischemic cerebrovascular disease, is cerebral vasospasm, luminal stenosis and occlusion, including transient ischemic attacks (also known as a transient ischemic attack), cerebral thrombosis and cerebral embolism and lacunar infarction. Thrombosis is the most common stroke of a, it is in hypertension and atherosclerosis, on the basis of brain artery wall thickening and luminal stenosis, intima rough and platelet adhesion and easily assembled, or even blood coagulation and blood viscosity increased due to the slower pace. When the cerebral vascular stenosis occurred completely blocked, it has resulted in regional cerebral ischemia, softening, necrosis, etc., pathological changes, which have hemiplegia, aphasia, sensory dysfunction and other nerve dysfunction symptoms. In addition, low blood pressure, high blood cholesterol, high blood coagulation state as hemodynamics and blood rheology of abnormal changes can lead to cerebral thrombosis.
