Endovascular therapy for ischemic stroke is considered within what timeframe?

Endovascular therapy for ischemic stroke is considered within what timeframe?

• A. Only after CT shows occlusion on CTA
• B. Within appropriate time windows
• C. In all patients regardless of time
• D. Not used in ischemic stroke

Answer: (B)

Endovascular therapy is a time-dependent treatment, and the key is offering it within established time windows from when symptoms started (or from the last known well time). Rapid imaging is used to confirm the presence of a proximal occlusion and salvable brain tissue, but the main decision driver is timing. That’s why the best answer is: within appropriate time windows. It's not limited to confirming an occlusion on CTA before considering treatment, it's not given to all patients regardless of time, and it is definitely used in eligible cases of ischemic stroke.
