There were two types of our modified triple-branched stent graft. In type 1 modified triple-branched stent graft, all 3 sidearm tube grafts and distal portion of main tube graft were stented while the proximal portion of main tube graft was unstented before implantation (A). In type 2 modified triple-branched stent graft, only the distal portion of the main tube graft was stented while all 3 sidearm tube grafts and the proximal portion of main tube graft were unstented before implantation (B). The main tube graft and 3 sidearm grafts were individually mounted on 4 catheters and restrained by 4 silk strings (C).
