Craniocerebral injuries that require emergency surgery include subdural hemorrhage, epidural hemorrhage, subarachnoid hemorrhage, and brain herniation from various causes. Emergency surgery is called “emergency surgery” in medicine. 1. Subdural hemorrhage: most of the subdural hemorrhage caused by trauma is caused by rupture of cortical arteries due to violence. After the injury, the patient will be in coma, which is progressively aggravated, and when the amount of hemorrhage is larger, it will increase intracranial pressure and lead to cerebral hernia, which requires emergency surgery and hematoma removal surgery. When the amount of bleeding is small, conservative treatment can be chosen. 2. Epidural hemorrhage: generally trauma caused by rupture of the middle meningeal artery, after the injury, the patient is comatose, there will be an intermediate period of wakefulness, generally can be treated conservatively, antifibrinolytic and hemostatic drugs to stop bleeding, a few patients with large amounts of bleeding, craniotomy hematoma removal surgery. 3. Subarachnoid hemorrhage: mostly caused by trauma rupture of intracranial blood vessels, blood flow to the arachnoid space, a small amount of subarachnoid hemorrhage, the feasibility of mannitol to reduce intracranial pressure, reduce cerebral edema, antifibrinolytic and hemostatic drugs to stop bleeding. In case of large amount of bleeding, cerebrospinal fluid drainage or even craniotomy is needed. 4. Brain herniation caused by various reasons: such as cerebral contusion and intracerebral hematoma causes brain herniation, also need emergency surgery. Since all the above diseases are serious and life-threatening if not handled properly, it is recommended to go to the hospital in time if you have any related problems to avoid delaying your condition.
