In clinical practice, patients with subarachnoid hemorrhage are usually hospitalized for about 14-21 days, but it must be evaluated according to the actual condition of the patient. If the subarachnoid hemorrhage is very simple and there is no other aneurysm, arteriovenous malformation, etc., the patient can be discharged from the hospital in about 7-10 days, and can be reviewed regularly at a later stage. However, some subarachnoid hemorrhages may have aneurysms, arteriovenous malformations and other vascular diseases, which require a longer hospital stay, and many of them require interventional embolization or craniotomy for further treatment. In some cases, subarachnoid hemorrhage is graded higher and more severe, and the length of hospitalization will be significantly longer, so it is important to take into account the actual situation in order to make a better judgment.
