Abstract
An artificial blood vessel that can be transplanted to blood vessels with a small diameter, can be adjusted to an arbitrary size of a diameter, improves in invasiveness when a graft is taken, and overcomes the problem on the provision of a graft is provided. An artificial blood vessel prepared from a decellularized tubular structure, which is prepared by processing a decellularized, sheet-like blood vessel (decellularized blood vessel sheet) into a roll structure, and a tissue adhesive, wherein a portion which is contacted with blood that flows within the artificial blood vessel consists of the tissue of the tunica intima lined with the tissue of the tunica media whereas a portion of the sheet that overlaps when the sheet is processed into a roll structure (overlap width) consists of the tissue of the tunica media and wherein a tissue adhesive is applied to the overlap width.
