Abstract
In this review, three recent studies using the National Cerebral and Cardiovascular Center (NCVC) rt-PA registry on arterial occlusion sites and early recanalization in patients with hyperacute ischemic stroke who underwent intravenous thrombolysis are introduced. Koga, et al. reported underlying factors associated with early recanalization failure following thrombolysis. Osaki, et al. reported the significance of the NIH Stroke Scale as simple clinical predictors of stroke outcome during 1-hour infusion of rt-PA. Sakamoto, et al. reported clinical characteristics and outcomes of thrombolyzed patients who showed reverse MRA-DWI mismatch on the initial MR images.
