What is the main therapeutic goal of mechanical thrombectomy in eligible LVO stroke patients?

• A. Quickly normalize blood pressure
• B. Improve functional outcomes
• C. Replace IV tPA
• D. Avoid sedation

Answer: (B)

Restoring blood flow to the brain area affected by a large-vessel occlusion is the primary aim. Mechanical thrombectomy focuses on quickly removing the clot to re-establish perfusion, with the goal of salvaging as much brain tissue as possible and improving long-term functional independence for the patient. When reperfusion is achieved promptly, there are better chances of regaining independence in daily activities (usually measured as a favorable score on the functional outcome scale around 90 days). While concurrent treatments like IV thrombolysis or supportive care play important roles, the core objective of thrombectomy is to maximize functional recovery by restoring blood flow.
