Clinical Comparison of a New Non-Sealed Woven Dacron Graft and Sealed Woven Dacron Grafts / 日本心臓血管外科学会雑誌

ABSTRACT

The UBE woven 150cc WYK graft is a non-sealed graft that became available commercially in January 2005, and does not need to be preclotted before implantation. Subjects in this study comprised 50 patients with abdominal aortic aneurysms or common iliac arterial aneurysms, who received prosthetic Y grafts in our institution. Subjects were divided into 2 groups the U group (<i>n</i>=26), with implantation of the UBE graft, and the I group (<i>n</i>=24) who received implantation of an INTERGARD^TM woven Y graft. Intraoperative bleeding, inflammatory response and duration of postoperative hospitalization were evaluated in each group. Significant differences were noted between C-reactive protein levels, frequency of recurrence of fever and duration of postoperative hospitalization. No differences were noted between intraoperative bleeding and time. The UBE woven 150cc WYK graft, compared with the INTERGARD^TM woven Y graft, required no extra time for implantation and appeared to offer advantages such reduced immunoreaction after surgery. However, follow-up for sufficient late-phase evaluation of the grafts is required.
