Outflow switch technique during the left heart bypass to prevent the distal embolization in the distal aortic arch surgery.

Aortic cross-clamping has the risk of inducing the postoperative embolization including the stroke during the repair of distal aortic arch with the use of left heart bypass. In this paper, we present a modified technique to reduce the embolization by switching the outflow of the left heart bypass from left atrium to the side branch of the inserted graft.
