Abstract
A knitted dacron graft impregnated with collagen (HemashieldTM) was implanted in 31 patients. From October 1990 to September 1991, a clinical study was carried out in 28 males and 3 females with average age of 61 yr. In the 31 patients, 12 tube grafts and 19 bifurcation grafts were used. There was no death in these patients, and all grafts were patent. The mean intraoperative blood loss was 1, 100±1, 290 mls (±S. D.). Postoperative evaluation for inflammatory index and immunological responce revealed no significant changes. In conclusion, the HemashieldTM double velour MicrovelTM prosthesis is a safe and reliable vascular graft. By using HemashieldTM graft, intraoperative blood loss can be
decreased
