Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Thrombectomy
Penumbra™ System
Patients assigned to the Thrombectomy arm will be conducted to the angio suite. Mechanical thrombectomy will be attempted with the use of the Penumbra™ System, and can be assisted by intraarterial thrombolysis (rTPA up to 20 mg)
Usual Care
Recombinant tissue plasminogen activator
Patients assigned to Usual Care arm will be thrombolysed according to the NINDS protocol (rtPA 0,9 mg/kg, 10% IV bolus and remaining in the next hour, up to 90 mg)
