Complex aortic arch procedures pose significant challenges to the cardiac surgeon, as well as significant morbidity to the patient. Different techniques for preservation of cerebral and distal organ function have been demonstrated.^1-3 Numerous publications have suggested using total circulatory arrest with systemic temperatures of less than 18°C, but this method can be associated with long operation times and severe coagulation disorders. More recently, antegrade cerebral perfusion has generated increasing interest because it allows aortic arch operations at mild hypothermia.⁴ For complex procedures, preservation of spinal cord and abdominal organ function remains a problem with this technique, possibly leading to postoperative acute renal failure, neurological deficits, or malfunction of intestinal organs.

This work describes our initial experience with a new perfusion cannula, allowing perfusion of cerebral vessels and the descending aorta with one cannula (Figure 1). This perfusion setup enables "warm" arch surgery with optimal brain and distal organ perfusion, avoiding circulatory arrest with attention to comfortable conditions at the distal anastomosis of the . . .
