Brain protection in open arch surgery

Area of Science:

• Cardiovascular Surgery
• Neurology
• Hypothermia Research

Background:

• Aortic arch surgery is complex, with significant risks of perioperative neurological injury.
• Understanding hypothermia's role and neurological insult mechanisms is crucial for patient safety.
• Effective cerebral protection strategies are paramount during aortic arch procedures.

Purpose of the Study:

• To review the historical evolution of aortic arch surgery.
• To examine hypothermia classifications and mechanisms of neurological injury.
• To compare outcomes of different cerebral perfusion strategies and discuss current trends.

Main Methods:

• Literature review of aortic arch surgery history.
• Analysis of hypothermia classifications and neurological injury mechanisms.
• Comparative literature analysis of deep hypothermic circulatory arrest, retrograde cerebral perfusion, and antegrade cerebral perfusion outcomes.

Main Results:

• Exploration of risk factors for perioperative neurological insults.
• Evaluation of available cerebral monitoring systems.
• Discussion of technical considerations for cerebral perfusion and temperature management.

Conclusions:

• Deep hypothermic circulatory arrest, retrograde cerebral perfusion, and antegrade cerebral perfusion have distinct outcomes.
• Optimizing cerebral perfusion and temperature management is key to mitigating neurological injury.
• Contemporary trends focus on enhancing cerebral protection during aortic arch surgery.
