Early neurological deterioration following thrombolysis for minor stroke with isolated internal carotid artery occlusion

Abstract

Early neurological deterioration is a frequent and highly deleterious event after IVT for minor stroke with iICAo, and is of thromboembolic origin in three out of four patients. The strong association with iICAo site-largely a function of underlying stroke etiology-may point to a different response of the thrombus to IVT. These findings suggest END may be preventable in this setting.
