摘要：

Objective: New technologies are being explored to meet the clinical need for an 'off-the-shelf' small diameter vascular graft with superior or at least equivalent properties to autologous vessel. The field of nanotechnology and fabrication promises major advances in biomaterial design and wall structure to deliver biomimetic grafts. This review brings together recent work on this topic. Methods: A literature search was conducted of PubMed and ISI Web of Knowledge using relevant keywords: Articles published after January 2005 were given preference. Personal communications and PhD theses were also used as sources. Results: An evolving focus on surface patterning of biomaterials has been found to carry great potential. Influencing cellular behaviour on prosthetic grafts using graft luminal surface modulation at the micro- and nano-levels is the basis of this recent concept in vascular graft development. Conclusion: This technology may deliver small diameter grafts with the potential for spontaneous in situ endothelialisation without the need for prior 'seeding', with the potential to open a new chapter in vascular graft development.
