ABSTRACT
OBJECTIVE:
Cerebral vasospasm is a common complication after aneurysmal subarachnoid hemorrhage (aSAH). Many drugs have been tried to mitigate cerebral vasospasm and delayed cerebral ischemia. Cilostazol, a selective inhibitor of phosphodiesterase 3, is a promising agent in preventing cerebral vasospasm and delayed cerebral ischemia after aSAH. The objective of this article was to ascertain the effect of cilostazol on cerebral vasospasm after aSAH by performing meta-analysis and trial sequential analysis.METHODS:
A systematic search of the literature was performed, and all the eligible randomized controlled trials were included in the meta-analysis and trial sequential analysis.RESULTS:
A total of 454 articles were identified using the search criteria. Six articles were selected for systematic review and the 4 randomized controlled trials were included in the meta-analysis. The pooled odds ratio for symptomatic vasospasm, new-onset infarct, and angiographic vasospasm was 0.35 (95% confidence interval [CI], 0.21-0.59; P < 0.0001), 0.38 (95% CI, 0.21-0.66; P = 0.0007) and 0.49 (95% CI, 0.31-0.80; P = 0.004), respectively. The pooled risk ratio for unfavorable outcome was 0.52 (95% CI, 0.37-0.74; P = 0.0003).CONCLUSIONS:
Cilostazol decreases the prevalence of symptomatic vasospasm, new-onset infarct, and angiographic vasospasm when administered after aSAH. Trial sequential analysis increased the precision of our results because the defined thresholds of effect were met by the available studies. However, further studies involving patients from other geographic areas are required to confirm the generalization of the results.Palavras-chave
