“Central” Intraarterial Thrombolysis Using a Newly Developed Low Friction Guidewire/Catheter System

Abstract

Fibrinolytic therapy for cerebral embolism was initially accomplished by intravenous administration of urokinase and streptokinase. Although this was technically easy, results were far from satisfactory; no significant change was seen in treated patients compared with the control group, and mortality rate was high among the treated group [1]. Therefore, this method was abandoned. In recent years, clinical trials in treating patients with cerebral embolism by intravenous administration of a new fibrinolytic agent recom­binant tissue plasminogen activator (rt-PA), which has a strong affinity to fibrin in the embolus, have been done. This was said to be effective compared to the control group, but the reported recanalization rate, which was 30%–50%, was not yet satisfactory [2,3]. Furthermore, this seems to be more effective for small emboli lodging in the cortical branches than large emboli lodging in the more proximal arteries.
