Cerebral hemorrhage surgery is a time window, cerebral hemorrhage treatment emphasizes a ' early ' word, the earlier the intervention will minimize cerebral hemorrhage mortality and morbidity. It is now believed that 80 % of patients with cerebral hemorrhage hematoma enlargement occurred in the onset of 3-6 hours, can also occur within 12 hours. The most feared clinical is re-bleeding, re-bleeding many factors, are currently considered to include high blood pressure, pre-morbid aspirin or other antiplatelet drugs, broken into ventricles of the brain and so on. It is generally believed that the lesion is still in the acute phase within 72 hours, and the secondary injury has not been fully initiated, and the intervention after 72 hours may not be conducive to the recovery of brain nerves.
Therefore, the best operation time for cerebral hemorrhage is between the hyperacute phase and the acute phase, that is, 6 hours after bleeding, within 72 hours. Or more conservative is between 12 hours to 24 hours. In addition, for patients with cerebral hernia and pre-cerebral hernia, more early intervention should be emphasized. Minimally invasive surgery can also be beneficial for patients with increased intracranial pressure over 72 hours of bleeding.
