Subarachnoid hemorrhage (subarachnoid hemorrhage SAH) is one of the most common cerebral vascular disease, the hemorrhage of acute onset, more complications, although the diagnostic equipment and treatment progress, but still has a very high mortality rate of SAH, the final outcome, probability and the method of treatment depends largely on the occurrence of complications is appropriate. It is of great value to improve the prognosis of subarachnoid hemorrhage by early diagnosis, accurate assessment and timely treatment of complications. Although the progress of the diagnosis and treatment equipment, still has a very high mortality rate and disability rate of subarachnoid hemorrhage, the total mortality rate was about 50%, of which 10% ~ 15% of the patients died on the way home or to the hospital, 1 / 3 of the survivors of life can not take care of themselves, seriously affecting the quality of life of patients. It is of great value to improve the prognosis of subarachnoid hemorrhage by early diagnosis, accurate evaluation and reasonable treatment. The severity often received Hunt Hess grade, Hunt grade of Hess is affected the prognosis of patients with subarachnoid hemorrhage risk factors, the higher grade, the worse the prognosis. That important independent risk Hunt Hess classification is not the poor prognosis of subarachnoid hemorrhage factors in this study, but negatively correlated with clinical prognosis, showed that the higher the grade, the lower the GOS score, the worse the prognosis. Often occurs in the pathogenesis of cerebral vasospasm after subarachnoid hemorrhage in 3 ~ 14d, 5 ~ 7d peak, vasospasm supply region of cerebral blood flow with spasm severity decreased; the mortality rate of rebleeding was significantly increased, the first bleeding mortality rate is about 12%, after the first hemorrhage survivors 69% rebleeding, re hemorrhage death rate was 72%. The reported symptomatic cerebral vasospasm occurred in 20% symptomatic cerebral vasospasm and rebleeding is an important independent risk of subarachnoid hemorrhage prognostic factors, so the prevention and treatment of symptomatic cerebral vasospasm and bleeding to reduce the mortality rate and disability rate has very important significance for subarachnoid hemorrhage. In patients with complications of hydrocephalus, 8.7% seizures, show an important independent risk of hydrocephalus, seizures are not poor prognosis of subarachnoid hemorrhage, hydrocephalus, but seizures are negative prognosis related factors showed that the higher the grade, hydrocephalus, seizures, complications, clinical prognosis.
