A new woven double velour vascular prosthesis designed to minimize intraoperative blood loss was implanted in 24 animals. Grafts were examined at 3 to 12 month intervals for healing and were compared to woven non-velour grafts implanted in 13 control animals. At 12 months, the velour grafts were 93 to 98% covered with neointima while the control grafts were only 86% covered with neointima. The neointima on the velour grafts was thinner (60 mu) and more vascular than that on the control grafts. Woven double velour grafts were implanted in 20 patients. Minimal bleeding occurred through the grafts which did not require preclotting, were easy to sew, and did not fray.
