Abstract:

BACKGROUND: Many scholars have successfully applied silk fibroin into small-caliber vascular prostheses to achieve better anti-thrombotic role and excellent mechanical strength. In the animal experiments, an ideal long-term patency has been achieved.

OBJECTIVE: To summarize the biochemical properties of silk fibroin, the currently used methods for the vessel modification, as well as specific applications of silk fibroin in small-caliber vascular prostheses.
Methods: A computer-based search of CNKI, Medline database and ScienceDirect databases from January 1980 to December 2013 was performed for articles relevant to small-caliber vascular prostheses with the key words of “vascular grafts, silk fibroin” in Chinese and English.

RESULTS AND CONCLUSION: Silk fibroin has controllable mechanical properties and good biocompatibility. Its decomposition products is well known and non-toxic. In addition, silk fibroin is easy to be integrated by anticoagulant group, and the effect is obvious, reliable, and easy for colonization and growth of endothelial cells, which can bring a satisfactory long-term patency. So, silk fibroin is an ideal material for the small-caliber vascular prostheses. However, due to the production process and other issues, the application of silk fibroin in previous studies has no long-term development. Recently, the development of nano-materials, bionic technology, vascular tissue engineering, and electrospinning technology brings new chances for the application of silk fibroin in artificial vessels.
