Subarachnoid hemorrhage is a rather dangerous disease with very high mortality and disability rates. It mainly manifests as sudden severe headaches, nausea, and vomiting, and complications such as bleeding, cerebral vasospasm, and electrolyte disorders can occur. The most common cause of subarachnoid hemorrhage is due to the rupture of an aneurysm. Therefore, it is generally advocated that patients with subarachnoid hemorrhage undergo surgery as soon as possible. The surgical method mainly involves local anesthesia, and a complete cerebral angiography is performed to check for the presence of an aneurysm. If an aneurysm is present, an interventional embolization can be performed, which causes less trauma and generally has a better prognosis. If there is a large amount of bleeding and the patient's life is in danger, a craniotomy may also be necessary. Thus, patients with subarachnoid hemorrhage need to undergo surgical treatment.
