Abstract
A newly arterial graft, a fibrocollagenous tissue tube supported by polyester mesh, was evaluated as a substitute for a small caliber artery.
The graft itself had no antithrombogenecity, which was usually required for small vessel substitute. The newly formed vascular wall was soft and stable. The graft showed good endothelization of the neointima and good affinity to the arterial wall. Once the patency was established at an early period of implantation, the patency extended over a long period, and the rate of the graft was 73% from 0 to 7 months following the operation
