The ascending aorta and the aortic arch curve 3-dimensionally from the right front of the heart to its left rear. If this curve is replaced or connected with a straight artificial graft, the curve will lose its natural shape. Here, we reconstructed the ascending aorta and the aortic arch with 2 different types of grafts, and devised a 3-dimensional (3D) structure by anastomosis.

“3D anastomosis” first involves reconstructing the ascending aorta and the aortic arch with separate grafts. An oblique incision was then made at the proximal stump of the aortic arch graft so that its tip pointed to the right side of the patient. Similarly, an oblique incision was made at the distal stump of the ascending aorta graft so that its tip pointed to the anterior position of the patient. Then, the 2 grafts were anastomosed in a twisted manner of 90 degrees. Therefore, a 3D form was created from the right front of the heart to its left rear. We achieved good results in 14 patients using this method.
