The recovery time of cerebral hemorrhage edema is related to the amount of bleeding, and there are also some individual differences, so it is impossible to make a generalization. In most cases, if the bleeding is small, a few milliliters or a dozen milliliters, and the edema is small in extent, it is usually absorbed in about 1 month. If the bleeding is large or recurrent, the recovery time may extend up to 3-4 weeks. The occurrence of cerebral edema is a necessary pathophysiological process that leads to the aggravation of the patient’s condition after cerebral hemorrhage. It starts rapidly and progresses rapidly, and can form serious complications such as brain herniation, so when edema after cerebral hemorrhage occurs, it should be treated actively. Dehydrating agents such as mannitol or glycerol fructose should be used after cerebral hemorrhage edema to lower the intracranial pressure and protect the normal metabolic activity of brain cells. Craniotomy for hematoma removal or endoscopic removal of hematoma and hemostasis are also options. Debulking decompression surgery and extraventricular drainage can also be used to enable patients to directly relieve hematoma compression, relieve intracranial hypertension, and promote rapid recovery.
