Answer

An alternative to systemic thrombolysis is local intra-arterial thrombolysis using a lower dose. Endovascular techniques have been used for achieving acute revascularization after ischemic stroke within a longer therapeutic window from symptom onset. At present, no drugs are approved by the FDA for intra-arterial treatment of AIS, and such therapy is not standard.

Intra-arterial thrombolysis is an option for treatment of selected patients who can be treated within 3-6 hours after the onset of symptoms due to occlusion of the middle cerebral artery and who are not otherwise candidates for IV tPA. [59, 60, 61]
