Neuroradiologic evaluation of patients with acute stroke treated with recombinant tissue plasminogen activator. The rt-PA Acute Stroke Study Group.

Abstract

Emergency cerebral angiography, which can be carried out relatively safely, adds important information about the nature and extent of the arterial occlusions, and the recanalization efficacy of fibrinolytic therapy for patients with acute stroke. Fibrinolytic therapy can be carried out with a relatively low complication rate that still needs to be correlated with the clinical benefits of the treatment. Fibrinolytic therapy in the doses utilized in this study, is more effective with distal than with proximal carotid territory occlusions.
