A comparative investigation of the pathogenetic factor in symptomatic cerebral vasospasm was made by quantitative histological and clinical studies in four patients who died immediately of symptomatic cerebral vasospasm (Cases 1-4) and in two who died without fatal cerebral vasospasm (Cases 5 and 6). Histological examination of the brain from Cases 1 and 2 found many white and fibrin microthrombi together with ischemic and infarctic changes in the territories of spastic arteries, which corresponded to the low-density areas (LDAs) observed on computed tomographic (CT) scans and the typical neurological symptoms. In Case 3, who had suffered severe vasospasms in bilateral anterior cerebral and middle cerebral arteries, bilateral LDAs were observed on CT scans and multiple fibrin thrombi were seen diffusely throughout the brain. In Case 4, extensive bilateral LDAs (lt greater than rt) were observed on CT scans, and multiple microthrombi were seen diffusely but predominantly in the left cerebral hemisphere. Only in Case 3 the possible complication of disseminated intravascular coagulation could not be ruled out. Only negligible thrombi were observed in Cases 5 and 6, whose immediate cause of death was considered to be acute hydrocephalus and aneurysmal rerupture, respectively. Distributions of microthrombi were significantly greater in the regions clinically identified to have been ischemic or infarctic.

Vasospasm is one of the most common complications after aneurysmal subarachnoid hemorrhage.Statins have been proven to be effective to reduce the incidence of vasospasm both in experimental subarachnoid hemorrhage and several clinical trials before. This meta-analysis aimed to investigate the efficacy of statins for patients with aneurysmal subarachnoid hemorrhage. We made strict search strategies to select the randomized controlled trial and observational studies published up to December 20(th) 2014. Outcomes of interest were cerebral vasospasm, delayed cerebral ischemia and poor outcome. Data analyses of RCTs and observational studies were made separately. Finally six randomized clinical trial and eight observational studies were included in this meta-analysis. There were in total 1031 patients in six RCTs with 504 patients received statins and 527 patients in placebo group. 561 patients with statins compared with 1579 patients in no statin-use group were finally included in 8 observational studies. Outcomes included in this meta-analysis (cerebral vasospasm, DIC and poor outcome) all indicated no statistical significance between two groups both in RCTs and observational studies. No benefits of statins-use for patients with aneurysmal subarachnoid hemorrhage were observed in both RCTs and observational studies, which was quite different from the results of several previous meta-analysis.
