In the cerebral edema scenario, what was the surgical intervention performed to address the problem?

• A. Thrombectomy to relieve increased intracranial pressure
• B. Carotid endarterectomy
• C. Craniotomy for hemorrhage control
• D. Ventriculostomy to reduce pressure

Answer: (A)

Restoring blood flow promptly is crucial when edema is driven by ischemia. Endovascular thrombectomy removes the clot in the occluded vessel, re-establishing perfusion to at-risk brain tissue. By saving more tissue from infarction, the overall amount of swelling and secondary edema is reduced, which helps prevent rising intracranial pressure. Other options address different issues: craniotomy targets hemorrhage or mass effect from bleeding, ventriculostomy drains CSF to relieve pressure without addressing the underlying occlusion, and carotid endarterectomy treats carotid stenosis but isn’t an acute reperfusion therapy for a recent occlusion. So, removing the clot to restore flow directly targets the cause of edema and mitigates its impact.
