Abstract
BACKGROUND AND PURPOSE:Cerebral edema is associated with poor outcome after IV thrombolysis. We recently described the TURN score (Thrombolysis risk Using mRS and NIHSS), a predictor of severe outcome after IV thrombolysis. Our purpose was to evaluate its ability to predict 24-h cerebral edema. METHODS: We retrospectively analyzed data from 303 patients who received IV rt-PA during the NINDS rt-PA trial. Measures of brain swelling included edema, mass effect and midline shift assessed at baseline, at 24 h and new onset at 24 h. Outcome was assessed using intracerebral hemorrhage (ICH), symptomatic intracerebral hemorrhage (sICH), 90-day severe outcome, and 90-day mortality. Statistical associations were assessed by logistic regression reporting odds ratios (OR) and by areas under the receiver operating characteristic curves (AUROC). RESULTS:Baseline brain swelling did not predict poor outcome; however, 24-h brain swelling predicted ICH (OR 5.69, P < 0.001), sICH (OR 9.50, P = 0.01), 90-day severe outcome (OR 7.10, P < 0.001), and 90-day mortality (OR 5.65, P = 0.01). Similar results were seen for new brain swelling at 24 h. TURN predicted 24-hour brain swelling (OR 2.5, P < 0.001; AUROC 0.69, 95 % CI 0.63-0.75) and new brain swelling at 24 h (OR 2.1, P < 0.001; AUROC 0.67, 95 % CI 0.61-0.73). CONCLUSIONS:Cerebral edema at 24 h is associated with poor outcome and 90-day mortality. TURN predicts ischemic stroke patients who will develop 24-h cerebral edema after IV thrombolysis.
