How is cerebral hemorrhage formed?

The most common cause of cerebral hemorrhage is high blood pressure combined with arteriosclerosis of small and thin arteries. Hypertension for a long time causes vitreous degeneration and fibrin necrosis of small and thin arteries in the brain, and the elasticity of the vessel wall is weakened. When blood pressure rises suddenly, blood vessels are easy to rupture and bleed. Under the impact of blood flow, the lesion of the vessel wall can also cause the formation of small aneurysms. When blood pressure fluctuates violently, small aneurysms rupture and cause cerebral hemorrhage. The incidence of hypertensive cerebral hemorrhage in the basal ganglia region is the most common, mainly because the supply of bean veins here from the middle cerebral artery was sent out at right angles, on the basis of the original vascular lesions, by the high pressure of blood flow impact, the formation of vascular rupture.
