There is a specific type of subarachnoid hemorrhage that carries a high risk of rebleeding because there is no tissue compression around the vessel. Rebleeding may be induced by strenuous activities, forceful coughing, emotional excitement, and even defecation. Therefore, patients are advised to stay absolutely bedridden for 1 month, during which time they should avoid strenuous activities, and may turn and turn slightly. A common cause of subarachnoid hemorrhage is aneurysm rupture. Once the symptoms of subarachnoid hemorrhage are present, the patient should be screened for aneurysm rupture as early as possible, and if rupture occurs, aneurysm embolization should be performed in a timely manner. After aneurysm embolization, if there is no hydrocephalus or high cranial pressure, the patient can get out of bed in about 2 weeks.
