Intraarterial Therapy in Acute Ischemic Stroke

Results of intraarterial urokinase (u-PA) infusion therapy for acute cases with thromboembolic occlusion of major cerebral arteries of the internal carotid artery (ICA), the middle cerebral artery (MCA), the posterior cerebral artery (PCA), and the basilar artery (BA) were reported at the First Symposium in Heidelberg in 1990 [1]. Clinical studies of intraarterial infusion of fibrinolytic agents have been continuing and amount to 94 cases up to the present.
