Insights
Direct innominate artery cannulation offers a novel approach for thoracic aortic surgery. This technique provides both systemic and selective antegrade cerebral perfusion, addressing challenges in arterial access and brain protection.
Area of Science:
- Cardiovascular Surgery
- Thoracic Aortic Surgery
- Cerebral Perfusion
Background:
- Arterial cannulation in thoracic aortic surgery is complex due to surgical site and cerebral protection needs during circulatory arrest.
- Common cannulation sites (ascending/descending aorta, axillary, carotid, femoral arteries) have limitations and risks.
- The innominate artery presents a viable alternative for cannulation, either directly or via a graft.
Purpose of the Study:
- To present a novel technique for sole direct innominate artery cannulation.
- To demonstrate its capability for providing systemic and selective antegrade cerebral perfusion during aortic surgery.
Main Methods:
- Direct cannulation of the innominate artery.
- Utilizing this site for both systemic circulation and targeted cerebral perfusion.
Main Results:
- Successful implementation of sole direct innominate artery cannulation.
- Achieved both systemic and selective antegrade cerebral perfusion.
Conclusions:
- Direct innominate artery cannulation is a feasible and effective alternative for thoracic aortic surgery.
- This technique enhances cerebral protection and addresses limitations of traditional cannulation sites.
Abstract:
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.
