Perigraft-to-right atrial shunt for aortic root hemostasis

We have modified the technique of perigraft-to-right atrial shunt to control hemorrhage after aortic root replacement. We have performed this operation in 2 patients, including one who had acute aortic dissection and another who underwent aortic root replacement and single-vessel coronary artery bypass. Neither patient required re-exploration for bleeding, and both shunts closed spontaneously during the follow-up period without any related complications. With this modification, even in the presence of concomitant coronary artery bypass grafting, hemostasis was achieved with preservation of the proximal vein graft.
