Anaesthesia for stroke thrombectomy: technical considerations based on outcome evidence

Area of Science:

• Neurology
• Interventional Neurology
• Anesthesiology

Background:

• Stroke is a leading cause of death and disability globally.
• Effective stroke treatment is critically time-sensitive.
• Rapid advancements in stroke therapies and guidelines necessitate updated management strategies.

Purpose of the Study:

• To review modern stroke management approaches.
• To discuss evolving treatment options and guidelines.
• To highlight the role of advanced imaging and interventional techniques.

Main Methods:

• Review of current literature on stroke management.
• Focus on mechanical thrombectomy for large vessel occlusion (LVO) strokes.
• Discussion of perfusion imaging techniques (CT and MRI) for extended treatment windows.

Main Results:

• Mechanical thrombectomy is the standard for LVO strokes.
• Perfusion imaging enables treatment in select patients beyond the standard time window.
• Both general anesthesia and conscious sedation are viable anesthetic options for thrombectomy.

Conclusions:

• Individualized anesthetic management is optimal for stroke thrombectomy.
• Close collaboration between anesthesiologists and neurointerventionalists is crucial.
• Key principles include minimizing treatment delays and maintaining cerebral perfusion pressure.
