Based on two patients suffering from chronic visceral ischemia, the an
atomic and pathophysiologic principles prior to surgery are discussed.
Antegrade revascularization is supposed to be better hemodynamically.
Complete revascularization of multiple arteries seems to be theoretic
ally superior to one-vessel procedures. Within the bypass procedures t
he aortic-celiac-mesenteric patch bypass could be an excellent surgica
l possibility combining antegrade with simultaneous revascularization
of celiac and superior mesenteric artery.
