Brief Summary:

Data from the literature have suggested that a longer time of thrombolysis might be more effective in ischemic stroke. We, the investigators at Hospices Civils de Lyon, have designed a randomized protocol to test this hypothesis. Moreover, the therapeutic window is 7 hours.

Rt-PA (alteplase) is injected intravenously in the 2 arms of the study for a duration of 60 minutes in the arm with a "classical dose" and 90 minutes in the arm with a "low dose-longer infusion".

This is a study of the outcome at 90 days.
