Evaluación de la escala Vasograde como predictor de Isquemia Cerebral Tardía en pacientes con Hemorragia Subaracnoídea Aneurismática en Hospital Carlos Van Buren de Valparaíso

Abstract

Objective: To evaluate the predictive value of VASOGRADE classification as a predictor of Delayed Cerebral Ischemia at the admission of patients with aneurysmal subarachnoid hemorrhage. Methods: Descriptive study of 59 patients admitted at Carlos Van Buren Hospital in 2014 for aneurysmal subarachnoid hemorrhage. Nine patients were excluded; 7 by derivation to another centres and 2 by death at acute period. They were classified in 3 groups VASOGRADE GREEN, YELLOW and RED based on characteristics of modified Fisher and initial WFNS. We calculated and compared the Odds Ratio between results of Delayed Cerebral Isquemia by every category of VASOGRADE of this study with the results of Delayed Cerebral Isquemia of the original article of VASOGRADE. Results: The risk of Delayed cerebral  schemia was higher in the Green category of this study than the original article (Odds ratio (OR), 1,3; 95% CI, 0,02-14,3). On the other hand the Yellow group of this study also had a higher risk than the yellow group of the original article (OR, 2,8; 95% CI, 1,12-6,86). The Red group had a large higher risk than the original Red group (OR, 16,6; 95% CI, 2,2-733,8). Conclusions: The VASOGRADE scale has been validated recently. It is a a tool that allows to stratify the risk of Delayed cerebral ischemia in an effective way. The VASOGRADE scale
is easy to apply and effective for predicting Delayed Cerebral Ischemia.
