[Management of acute stroke - guidelines from the Expert Group of the Section of Cerebrovascular Diseases of the Polish Neurological Society. Update 2013: thrombolysis].

Thrombolysis is the most effective therapy for ischaemic stroke. The current guidelines and approvals have limited its use to patients available for treatment within 4.5 hours of onset and those aged 80 or less. There are also a number of other limitations derived from clinical trial protocols, i.e. minor and major strokes. The available evidence has indicated its possible efficacy in patients treated within 6 hours of onset and not fulfilling other limitations. Last year, the results of the IST-3 (Third International Stroke Trial: Thrombolysis) and a meta-analysis of all available trials including IST-3 were published. They point out the possible benefit of thrombolysis in patients not meeting the current criteria, which has been acknowledged in the Polish guidelines for management of stroke.
