The Changing Landscape of Intravenous Thrombolysis for Acute Ischaemic Stroke

Intravenous thrombolysis remains the most accessible and effective reperfusion therapy available to patients with acute ischaemic stroke. Treatment with intravenous thrombolysis improves the odds of favourable functional outcome with the unacceptably low risk of haemorrhagic complications. Even in the current era of endovascular thrombectomy, intravenous thrombolysis remains the backbone of acute stroke treatment due to its accessibility and relative ease of administration. Since intravenous alteplase was first approved for acute ischaemic stroke in the mid 1990s, there have been significant advances in expanding the indication and time window for treatment, in addition to transitioning towards tenecteplase use for stroke thrombolysis. In this review, we will provide a narrative on the use of thrombolysis in acute ischaemic stroke including an up-to-date discussion on recent advances in thrombolytic therapy.
