If the brain aneurysm ruptures then the immediate professional help is required. The doctors should restore proper respiration and blood pressure. Furthermore, the bleeding must be stopped and the brain damage should be prevented. In the cases of unruptured small aneurysm, the medications are prescribed since the possibility of rupture is very small. Furthermore, the large brain aneurysm can be treated by a surgery. There are three kinds of surgeries for this condition: microvascular clipping, endovascular coiling and shunt surgery.
