An external velour warp-knit Dacron vascular prosthesis (8mm in internal diameter, 6cm in length), whose porosity is 1200cc/cm2/min at 120mmHg, was implanted in the descending thoracic aorta of 30 mongrel dogs. The dogs were sacrificed at different intervals between 2 weeks and 6 months.
All grafts were patent at sacrifice and no serious complication was observed. Thrombus free surface score was about 90％. Cell coverage on the flow surface was first observed near anastomoses in 1-month specimens and was almost completed in 2 months. Transinterstices healing was completed in 2 months. This excellent healing in a canine model would allow clinical availability of this graft.
