Continuous retrograde cerebral perfusion during an aortic arch operation.

An 81-year-old woman presented with acute aortic regurgitation in the setting of an aneurysm of the ascending aorta and arch. The aortic valve, ascending aorta, and arch were replaced with a composite graft during continuous hypothermic total-body perfusion. Continuous cerebral perfusion was carried out by low-pressure retrograde perfusion via the superior vena cava while perfusion of the lower body was maintained via a femoral arterial cannula.
