The Prediction of Malignant Cerebral Infarction by Molecular Brain Barrier Disruption Markers

Abstract
Background and Purpose— Space-occupying brain edema is a life-threatening complication in patients with large hemispheric stroke. The aim of the study was to determine whether molecular markers of endothelial damage may help to predict secondary brain edema and, secondly, to identify patients who could benefit from aggressive therapies such as decompressive hemicraniectomy or hypothermia. Methods— We studied 40 consecutive patients with malignant middle cerebral artery (MCA) infarction and 35 controls with massive MCA infarctions Results— Mean time from stroke onset to blood sampling was 6.3±4.8 in m-MCA and 7.7±6.0 hours in the control group ( P =0.63). Baseline characteristics were comparable in both groups. c-Fn and MMP-9 levels were significantly higher in patients with m-MCA than in controls (all P 16.6 μg/mL had the highest sensitivity (90%), specificity (100%), and negative and positive predictive values (89% and 100%, respectively) for the prediction of m-MCA infarction. Conclusions— A plasma c-Fn concentration >16.6 μg/mL at admission is associated with the development of m-MCA infarction with high sensitivity and specificity, suggesting that c-Fn might be useful in therapeutic decision making.
