Final answer:
Intra-arterial thrombolysis treatment can be used up to 6 hours from the last known normal. Thrombolytic agents like tissue plasminogen activator are crucial for breaking down clots in stroke patients within a specific time frame to improve outcomes.
Explanation:
The maximum time from the last known normal when intra-arterial thrombolysis for select patients can be used for treatment is 6 hours.
This treatment involves administering thrombolytic agents, such as tissue plasminogen activator, to break down abnormal clots.
In cases of thrombotic stroke, administering thrombolytic agents within 3 hours can significantly improve the patient's prognosis.
