[Healing of an external velour warp-knit Dacron vascular prosthesis].
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.
