Subarachnoid hemorrhage is also relatively common in clinical settings. Its symptoms primarily include severe headaches, reflex vomiting, possible consciousness disturbances, and even seizures. Following the occurrence of subarachnoid hemorrhage, a cranial CT scan can be used for a definitive diagnosis. Patients typically seek treatment in neurology or neurosurgery departments. After admission to a neurology ward, DSA (Digital Subtraction Angiography) can be conducted to accurately locate the bleeding site, and interventional embolization treatments may be considered. If the patient has a large volume of subarachnoid hemorrhage, neurosurgery might be considered for the removal of intracranial hematomas or decompressive craniectomy, among other procedures.
