Prominent posterior cerebral artery (PCA) laterality upon 3-dimensional time-of-flight magnetic resonance angiography is often encountered in patients with middle occlusion. We hypothesized that this sign correlated improved functional outcome occlusion treated intravenous recombinant tissue plasminogen activator.Fifty acute ischemic stroke were activator from April 2007 to October 2009. All routinely underwent initial (first 3 hours) scans on admission, and additional follow-up (14-21 days after onset) computed tomography scans. Two film readers blinded all clinical information assessed the presence or absence of PCA angiography. retrospectively analyzed radiologic data patients.Out 50 patients, 20 showed National Institute Health Stroke Scale score 7 onset was significantly lower (P=0.007), infarct volume smaller (P=0.009) than without sign. Multivariate logistic regression analyses an adjusted odds ratio 8.49 for a favorable (modified Rankin 0-1 at 6 months) (95% CI: 1.82 55.8, P=0.005).The before can be used as predictor occlusion, probably due improvement recanalization rate.
