| ObjectivesThe purpose of this study was to evaluate prognostic factors for outcome by analyzing the clinical data of 53 patients with severe subarachnoid hemorrhage.Methods1. Literature ResearchBased on the literature review of current aneurysmal subarachnoid hemorrhage on prognosis of factors, it's found that the current evaluation of the importance of each factor varies, and even to the contrary conclusion. Severe cases in which the treatment is still a problem, and the prognosis is hardly satisfactory, little is discussed about the prognostic factors of this sub-group.2. Clinical ResearchClinical data were analyzed from 53 patients with Hunt-HessⅣⅤgrade aneurysmal SAH between 2005 and 2010. The outcome measure was the modify Rankin scale grade when discharge from hospital. The evaluation on prognosis from various factors has been investigated, such as gender, age at onset, aneurysm location and size, Claassen Scale, treatment, surgical timing, secondary surgeries, history of hypertension, and the TCM diagnosis.ResultsBy analyzing the clinical data, there are no significant differences between the factors as gender, age at onset, aneurysm location and size, treatment, surgical timing, TCM "Yin-Yang" diagnosis and the modify Rankin scale grade when discharge(P>0.05). But there are significant differences between the factors as Claassen Scale, history of hypertension, secondary surgeries, TCM "close-exhaustion syndrome" diagnosis and the modify Rankin scale grade when discharge(P<0.05).ConclusionsThe incident of intracranial aneurysms of female is higher than that of male. Female appears to have higher risks of aneurysm rupture and severe subarachnoid hemorrhage than male; prognosis has no relativity with the factors as gender, age at onset, aneurysm location and size, surgical timing, treatment, and TCM "Yin-Yang" diagnosis; while Claassen Scale, history of hypertension, secondary surgeries, and TCM "close-exhaustion syndrome" diagnosis are associated with the prognosis.
