A new low porous vascular prosthesis (TORAY GRAFT) fabricated from ultra-fine polyester fibers was implanted in 22 patients for surgical reconstruction of the total aortic arch. Subjects included Stanford A type aortic dissection in 12, aortic arch aneurysm in 3, arch and descending thoracic aortic aneurysm in 2, aneurysm from ascending to descending thoracic aorta in 2, distal arch aneurysm in 2 and AAE+AR+arch aneurysm in 1. Before operation, the grafts with four branches were prepared and preclotted with albumin. There were four hospital deaths, but no graft-related problems. This new vascular prosthesis was soft and pliable, and easily anastmosed even in the pre-clotted condition, and little bleeding was observed at the site of anastomosis and the graft itself. Furthermore, excellent neointimal formation reported previously urges us to expect the fewer graft-related problems in the long term follow up. We thought that the clinical use of this graft made of ultra-fine polyester fibers is useful for the graft replacement of total aortic arch.
