Direct Innominate Artery Cannulation as a Sole Systemic and Cerebral Perfusion Technique in Aortic Surgery.

Arterial cannulation is often challenging in thoracic aortic surgery due to the location of the surgery and need for cerebral protection during periods of circulatory arrest. Cannulation sites including the ascending and descending aorta, axillary, carotid and femoral arteries have limitations and are associated with complications due to their proximity to surrounding structures. Therefore, the innominate artery can be used by either direct cannulation or indirect cannulation via a graft as an alternative site. We present a technique of sole direct innominate artery cannulation that is able to provide both systemic and selective antegrade cerebral perfusion during aortic surgery.
