Three-region perfusion strategy for aortic arch reconstruction in the Norwood.

We describe a new method of selective regional perfusion during arch reconstruction in the Norwood procedure. The strategy involves direct sequential perfusion of the coronary and splanchnic circulations coupled with continuous cerebral perfusion, while repairing the arch in a distal to proximal fashion. This technique provides the potential for decreased coronary and splanchnic ischemic times, which in combination with continuous selective cerebral perfusion may further allow for warmer operating temperatures and decreased overall bypass times.
