The preparation of small-diameter blood vessels is an important part in the field of tissue engineering blood vessels, which has strong practicability in clinic. Synthesis of small-diameter vascular grafts is the basic of the construction of small-diameter artificial blood vessels. Electrospinning is a new technology of tissue engineering preparations. It can use a high voltage electrostatic field to produce micron grade even the nanoscale fibers. And through a series of processing, making the grafts simulate to extracellular matrix, cell adhesion and proliferation can be stimulated. In this paper, the materials, preparation technics, surficial decorations and evaluation system of the small-diameter tissue engineering blood vessel grafts were all reviewed.
