Coma after cerebral aneurysm surgery should be analyzed objectively according to the patient’s preoperative condition, as follows: 1. Surgery for unruptured aneurysm: Coma after surgery or interventional treatment should be taken seriously by doctors; because the patient is awake before surgery, the trauma and impact of surgery on the patient is usually temporary, and the patient should be awake after waking up from general anesthesia; if not, attention should be paid to If the patient is not awake, the patient should be checked for intracranial hematoma and new infarction; 2. Therefore, after surgery, although the aneurysm is clamped or blocked, the effect of bleeding on the patient’s brain still persists, and the patient’s coma will last for some time, and then the patient will gradually wake up as the blood is absorbed and the brain function is restored.
