Some patients with ruptured aneurysm hemorrhage can be cured, but a comprehensive consideration is necessary, depending on the severity of the patient’s condition and the amount of bleeding at the time of presentation. Currently, there is a preoperative grading of the severity of aneurysm hemorrhage patients, and the most commonly used grading is the Hunt-Hess grading, which is a good measure of the patient’s condition, including the prognosis of the surgery. The grading is very critical for preoperative judgment, and the prognosis is also very critical. In general, grade I-III patients should be operated as early as possible to prevent secondary hemorrhage and deal with the aneurysm before secondary hemorrhage. This part of the patients generally have a better surgical effect, the prognosis is also better, through the later treatment generally can gradually recover, or even return to normal, life can also be completely self-care. Grade VI-V patients have been told by preoperative evaluation that the prognosis is very poor and the recovery time is very long. Even if the aneurysm can be successfully treated by surgery, the acute hemorrhage will bring secondary neurological damage and brain damage, which is a big blow to the patient. Therefore, even if the operation is better, many patients end up with poor prognosis, which may be long-term coma, hemiplegia, severe disability or even unable to take care of their own life, and even some of the patients end up dying because they cannot be resuscitated. The specific performance of Ⅰ – V patients are as follows: 1, Ⅰ patients have no symptoms, or just mild headache or neck straightening; 2, Ⅱ patients will increase the degree of headache, moderate to severe headache and neck straightening, and cranial nerve palsy, including facial paralysis performance of the movable eye nerve palsy; 3, Ⅲ patients have appeared in the consciousness of the obstacles, including drowsiness, restlessness or confusion, some patients have begun to appear neurological dysfunction, including limb hemiparesis, hemiparesis, hemiparesis, and even some patients eventually can not be rescued and died. Including limb hemiparesis, limb dysfunction; 4, Ⅳ patients have been coma, may lead to moderate to severe hemiparesis, early to go to the brain straightening and autonomic disorders; 5, Ⅴ patients have been deep coma, belongs to the state of near death.
