Brief Summary:
The purpose of this research study is to evaluate two standard approaches of supplying blood and oxygen to your brain during open heart surgery.

Condition or disease Intervention/treatment Phase
Aneurysm of Aortic Arch Procedure: Retrograde brain perfusion Procedure: Antegrade brain perfusion Not Applicable

Detailed Description:
The purpose of the clinical trial is to assess the best method of protecting the brain during long periods of circulatory arrest. The significance of this project will be to determine which method of brain protection (1) retrograde brain perfusion or (2) perfusion of the right subclavian artery with antegrade perfusion of the brain protects against brain injury after total arch replacement. Thus reducing the risk of stroke or neurocognitive deficits in patients undergoing this critical surgical procedure.

Arm Intervention/treatment
Active Comparator: Retrograde brain perfusion
Pt may be randomized to retrograde brain perfusion when having a repair of the ascending aortic artery (aorta) including the aortic arch. This is one of the standard methods used while the body and the brain are cooled down to sub-normal levels (hypothermia). This will take place while on the heart-lung machine.
 Procedure: Retrograde brain perfusion

Primary Outcome Measures :
  1. To determine what is the best method of brain protection during long periods of circulatory arrest [ Time Frame: 6 months ]

Secondary Outcome Measures :
  1. Will one method of brain protection be better than the other in prevention of post-op stroke and which method will provide freedom from postop neurobehavioural deficit at 6 months postop. [ Time Frame: 6 months ]
