Double aortic central cannulation for open thoracoabdominal aorta repair

Area of Science:

• Cardiovascular Surgery
• Thoracic Surgery
• Vascular Surgery

Background:

• Extracorporeal circulation is essential for descending and thoracoabdominal aortic repair.
• Current cardiopulmonary bypass (CPB) methods, including peripheral cannulation and left heart bypass, carry significant risks and drawbacks.
• Minimizing visceral and central nervous system ischemia is a primary goal during these complex aortic surgeries.

Observation:

• A video tutorial demonstrates an alternative CPB strategy using two simultaneous aortic perfusion cannulas (proximal and distal) and a single right atrial cannula, all inserted via the main incision.
• This technique was applied in two cases of descending or thoracoabdominal aortic repair.
• The cannulas were inserted through the main incision, avoiding femoral access.

Findings:

• The presented CPB technique offers the benefits of full CPB while mitigating proximal hypoperfusion syndrome.
• Utilizing central cannulas significantly reduces the risk of retrograde perfusion.
• Excellent venous drainage was achieved, and complications associated with femoral cannulation were avoided.

Implications:

• This alternative CPB strategy expands surgical options for extensive thoracoabdominal aortic repair.
• It enables tailored management for complex aortic diseases.
• The technique enhances safety and efficacy in managing high-risk aortic reconstructions.
