What is the time window for thrombolysis in ischaemic stroke, and when can it be extended?
Thrombolysis for ischaemic stroke is effective only within a 4.5-hour window from symptom onset. This window may be extended to 9 hours if CT perfusion or MRI shows evidence of salvageable brain tissue.
Key points
- The standard time window for thrombolysis in ischaemic stroke is 4.5 hours from symptom onset.
- The window can be extended to 9 hours when CT perfusion or MRI demonstrates salvageable brain tissue.
- Thrombolysis is contraindicated in haemorrhagic stroke.
