How I do it--sole innominate cannulation for acute type A aortic dissection.

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Vascular Access

Background:

• Acute type A aortic dissection requires complex surgical repair.
• Establishing safe arterial return for cardiopulmonary bypass and cerebral perfusion is critical.
• Various cannulation strategies exist, each with potential benefits and drawbacks.

Purpose of the Study:

• To describe and evaluate sole direct innominate artery cannulation for arterial return.
• To compare innominate cannulation with other established methods (femoral, axillary, aortic, apical).
• To highlight the advantages of innominate cannulation over right axillary cannulation.

Main Methods:

• Direct cannulation of the innominate artery for arterial return.
• Establishment of cardiopulmonary bypass and selective antegrade cerebral perfusion.
• Comparative analysis with femoral, axillary, direct aortic, and apical cannulation techniques.

Main Results:

• Sole direct innominate cannulation is presented as a method for arterial return.
• Innominate cannulation is suggested to possess the benefits of right axillary cannulation without its disadvantages.
• The technique is applicable in patients with suitable innominate artery anatomy.

Conclusions:

• Direct innominate artery cannulation is a potentially advantageous technique for specific patient populations undergoing acute type A dissection repair.
• It offers a safe and effective alternative for arterial return, particularly when compared to right axillary cannulation.
• Patient selection based on innominate artery condition is crucial for successful implementation.
