Association between Cerebral Microbleeds on T2*-Weighted MR Images and Recurrent Hemorrhagic Stroke in Patients Treated with Warfarin following Ischemic Stroke

摘要

Although accumulating evidence suggests the presence of microbleeds as a risk factor for intracerebral hemorrhage (ICH), little is known about its significance in anticoagulated patients. The aim of this study was to determine whether the presence of microbleeds is associated with recurrent hemorrhagic stroke in patients who had received warfarin following atrial fibrillation–associated cardioembolic infarction.
