Abstract:
No interstitial bleeding occurred in either type of grafts. By gross observation and under light microscopy, a smooth neointima was noticed on the surface of collagen coated grafts 30 and 90 days after implantation. In a series of 4 patients with Marfan's syndrome undergoing replacement of the aortic root, hemorrhage through the interstices of the graft was virtually eliminated. There was no complication in any patient after a follow up of 3 months. This study reveals that collagen-coated dacron grafts were totally impervious to blood during and after implantation. The collagen coating can promoting cell growth and graft healing and does not interfere with the physical properties of the dacron grafts. As a prosthesis of aorta replacement , it may be applied clinically with safety. If it is used as small diameter vascular prosthesis,the long-term patency may be improved.
