Intracranial aneurysm rupture is a very serious disease. Hemorrhagic stroke generally has several types of disease like hypertensive cerebral hemorrhage is the most common, and amyloid hemorrhage, smoldering hemorrhage, intracranial aneurysm hemorrhage. Aneurysm hemorrhage is an extremely critical disease, and the mortality rate for a single hemorrhage is generally 25%-30%. If patients do not pay attention to the first bleeding, many patients will have a second bleeding within a short period of time, usually within a week or 3-5 days, and the mortality rate of the second bleeding can reach 60%, and if the third bleeding is not treated in time, the mortality rate is basically 100%. Therefore, ruptured intracranial aneurysm is a very serious disease, so this kind of disease needs to be paid attention to. Once a small amount of subarachnoid hemorrhage is confirmed by CT scan, 80%-90% of the patients have ruptured aneurysm hemorrhage, then further CT examination should be done, and if necessary, angiography or DSA examination should be performed and timely treatment should be done.
