Cerebral parenchymal hemorrhage

Cerebral hemorrhage, also known as cerebral hemorrhage, refers to spontaneous hemorrhage in the non-traumatic brain parenchyma. The etiology is diverse, and most of them are caused by ruptured blood vessels of hypertension arteriosclerosis, so it is also called hypertensive cerebral hemorrhage. The close relationship between cerebral hemorrhage and hypertension is that about one-third of patients with hypertension have cerebral hemorrhage, and about 95% of patients with cerebral hemorrhage have hypertension. Cerebral hemorrhage is a common acute cerebrovascular disease in the elderly, with a high mortality and disability rate. It is the clinical type with the highest mortality rate in China. Cerebral hemorrhage accounts for 40% to 50% of all cerebrovascular diseases. 80% of cerebral hemorrhage occurs in the cerebral hemisphere, and 20% occurs in the lobe, brainstem, cerebellum and ventricle.
