Abstract
Antegrade selective cerebral perfusion has become the preferred choice for brain protection during aortic arch surgery. To perform antegrade selective cerebral perfusion, cannulas have been introduced directly into the ostia of the supra-aortic vessels (SAV) after institution of hypothermic circulatory arrest and opening the aortic arch. We describe a different surgical technique with a new type of cannula for antegrade selective cerebral perfusion. This cannula, called AV (Andrea Venturini) cannula, has been designed to be introduced in the SAV directly using a standard guidewire technique (Seldinger's technique). The AV cannula can also be introduced from the ostia of the SAV if preferred. The AV cannula can be introduced before the institution of hypothermic circulatory arrest and before opening the aortic arch. One great advantage of this technique is that the ostia of the SAV remain free from a cannula, allowing the operator easier access and a faster anastomosis or reimplantation.
