Is there any surgical treatment for comatose caused by cerebral hemorrhage ?

Complex: Depends on where the hemorrhage is located and why it occurred. If a subdural or epidural, surgical evacuation may help. Intracerebral location or subarachnoid hemorrhage may be difficult but if aneurysm or avm, might be useful to repair. However, coma may be sign of increased intracranial pressure, and rarely can this be shunted or decompressed. More often supportive care is best.
