Cerebral hemorrhage, also known as hemorrhagic stroke, is becoming more and more common in modern society, with a high incidence rate year after year. Due to its serious fatalities and the possibility of severe paraplegia and other disabilities, it has become one of the top three disease killers in human society, and the pain and burden it brings to patients, their families and society is enormous. For the rescue and treatment of such patients and to improve their quality of life, brain surgeons have put a lot of efforts and made great achievements, but neurosurgeons have found through long-term research that even in the population of successfully rescued patients, the percentage of reoccurrence of hemorrhage is not low, and the threat to patients’ lives after reoccurrence of hemorrhage is far greater than the first time. It is important to insist on long-term follow-up and guidance of treatment for patients after cerebral hemorrhage, and this will obviously help to improve the survival life of patients. It must be pointed out that for patients with cerebral hemorrhage without a definite cause, especially those without a history of hypertension and not too old, especially those with simple subarachnoid hemorrhage, the possibility of intracranial aneurysm or cerebral arteriovenous malformation must be highly suspected, and such patients should be scheduled for whole brain angiography as early as possible to clarify the diagnosis and take aggressive treatment, otherwise, even if the hemorrhage is absorbed and improves, the chance of recurrence of hemorrhage is higher. Otherwise, even if the hemorrhage is absorbed, the chance of reoccurrence of hemorrhage is very high, and repeated hemorrhage is a great risk to life.
