Extending the time window for thrombolysis

Extending the window for thrombolysis in acute stroke.

Will delays in treatment jeopardize the population benefit from extending the time window for stroke thrombolysis?

BACKGROUND AND PURPOSE Pooled analyses show benefits of intravenous alteplase (recombinant tissue-type plasminogen activator) treatment for acute ischemic stroke up to 4.5 hours after onset despite marketing approval for up to 3 hours. However, the benefit from thrombolysis is critically time-dependent and if extending the time window reduces treatment urgency, this could reduce the population ...

Review Study: Intravenous Thrombolysis, Time Window, Dosage, and Off-Label

Despite the development of Intravenous thrombolysis with tissue Plasminogen Activator (IVtPA) guidelines in each affiliated stroke center, protocol violations may be observed in each hospital with IVtPA facilities. An extensive search of scientific electronic databases including PubMed, OVID, Index Medicus, Index Copernicus, Google, ISI, and Scopus was performed with keywords of Thrombolysis, O...

Effects of extending the time window of thrombolysis to 4.5 hours: observations in the Swedish stroke register (riks-stroke).

BACKGROUND AND PURPOSE The European Cooperative Acute Stroke Study (ECASS) III trial and Safe Implementation of Thrombolysis in Stroke-International Stroke Thrombolysis Register (SITS-ISTR) data were published in 2008. Riks-Stroke, the Swedish Stroke Register, was used to explore how thrombolysis in the 3- to 4.5-hour window has been spread in different hospitals and patient groups and what eff...
