Innominate artery cannulation during aortic surgery.

Area of Science:

• Cardiovascular Surgery
• Thoracic Aortic Surgery
• Cerebral Perfusion Techniques

Background:

• Antegrade flow during thoracic aortic surgery, achieved via cannulation of the ascending aorta, axillary artery, innominate artery (IA), or carotid artery, is linked to better survival and neurological outcomes than femoral artery cannulation.
• The optimal cannulation site for both cardiopulmonary bypass (CPB) and antegrade selective cerebral perfusion during complex aortic procedures remains a subject of ongoing discussion.

Purpose of the Study:

• To present a specific surgical technique utilizing innominate artery (IA) cannulation.
• To detail the application of this technique for cardiopulmonary bypass (CPB) and antegrade selective cerebral perfusion in thoracic aortic surgery.

Main Methods:

• Description of the surgical technique involving cannulation of the innominate artery (IA).
• Application of the IA cannulation for establishing cardiopulmonary bypass (CPB).
• Implementation of antegrade selective cerebral perfusion via the IA during thoracic aortic repair.

Main Results:

• The study presents a detailed methodology for IA cannulation.
• The technique facilitates both CPB and selective cerebral perfusion.
• Outcomes associated with this specific IA cannulation approach are detailed (further results pending full study data).

Conclusions:

• Innominate artery (IA) cannulation provides a viable and effective method for CPB and antegrade selective cerebral perfusion in thoracic aortic surgery.
• This technique may offer advantages over traditional femoral cannulation for specific aortic pathologies, potentially enhancing patient safety and neurological protection.
