No results posted yet for this study

Summary

The purpose of this study is to determine whether intra-arterial rt-PA within 6 hours from an ischemic stroke onset, compared with intravenous infusion of the same drug within 3 hours, increases the proportion of independent survivors at 3 months.

Conditions

  • Stroke
  • Cerebrovascular Accident

Interventions

DRUG

local interarterial recombinant tissue plasminogen activator

Endovascular treatment must be performed asap after random.and definitely within 6h from symp. onset.It includes intrarterial thrombolysis with rt-PA,if necessary,associated to or substituted by mechanical clot disruption and/or retrieval.Fibrinolytic therapy should be performed within 1h,the full dose of rt-PA infusion should not exceed 0.9 mg/kg (max 90 mg in the case of body weight ≥100 kg).If a complete recanalization is achieved,rt-PA infusion can be interrupted before reaching the maximum dosage.The option of performing a thrombolysis by mechanical means to obtain a mechanical disintegration/shift/detach/fissure of the thrombus and/or a retraction/aspiration can be considered on the basis of the type,location and characteristics of the occlusion.These choices may involve the use of the microguidewire as a mechanical instrument to favour the disintegration of the thrombus,using systems to capture the thrombus by extraction or more complex systems to crush and aspirate the thrombus

DRUG

intravenous (IV) rt-PA

IV thrombolytic treatment is started immediately after randomization, within 4.5 h of symptoms onset. IV rt-PA is administered at a dose of 0.9 mg/kg (max 90 mg), 10% of which is given as a bolus, followed by the delivery of the remaining 90% as a constant infusion over 60 mins
