Biological Reaction to Small-Diameter Vascular Grafts Made of Silk Fibroin Implanted in the Abdominal Aortae of Rats

Results show that SF has a higher potential as a base of vascular grafts than the commercially available PET/G graft. The larger tissue infiltration area in PET/SF compared with that in PET/G also indicates the potential of SF as a coating material. In the present study, SF delivered promising results as base and coating materials for small-diameter vascular prostheses.
