Whether or not a brain hemorrhage from a car accident needs to be treated surgically is a judgment call based on the actual situation. Surgery is not a panacea, and sometimes even the condition will be more serious after the surgery is over, so it must be judged according to the actual situation. If you meet a patient with a brain hemorrhage in a car accident and want to really clarify whether surgery is needed, you have to meet several indications: 1. The amount of brain hemorrhage is relatively large and has seriously compressed the brain tissue, forming a manifestation of brain tissue displacement, which is commonly known as brain herniation, and definitely requires surgery after formation. 2. These are all signs of brain herniation. If any of these conditions occur, surgery must be performed. However, any surgery has certain risks and is not perfect.
