The diagnosis is affirmative. Traumatic brain injury leads to aneurysm rupture and bleeding. The aneurysm is located in C 1 segment of bilateral internal carotid arteries. Aneurysms of C 1 segment of internal carotid artery are not easy to be craniotomy. The only choice is intervention and observation.

There is no fixed value about the critical period of rupture, but it becomes lower and lower with the passage of time, and the risk is the highest in the first few days. Rupture risk is the average value of different aneurysms every year, which is of little reference significance to individuals. It is generally believed that the risk of rupture of all aneurysms is about 65,438+0%, that is, only one aneurysm in one hundred ruptures. But for those that have already ruptured, the risk of rupture is much higher. Therefore, active treatment of ruptured aneurysm is advocated. Unless you are in poor health.

The above is a relatively recognized concept of treatment, not from a specific literature.
