Antithrombotiques et infarctus cérébral : essais cliniques et besoins médicaux

Beside vascular risk reduction, other antithrombotic agents are used as thrombolytics in the acute phase of stroke. The rt-PA (recombinant tissue plasminogen activator) administered in the first 3 hours dissolves the clot, preventing death and handicap due to ischemic brain lesion. But time window is short and rt-PA increase the risk of hemorragic stroke. Combination of new thrombolytic agents and new imaging technics should permit to rise the number of treated patients.
