Abstract
A method of end-to-side anastomosis of blood vessels for connecting a side portion of a first blood vessel to an end portion of a second blood vessel involves holding a first site on the side portion of the first blood vessel using a holder, and partially elevating the side portion of the first blood vessel; superimposing a second site on the side portion of the first blood vessel on the end of the second blood vessel and fixing them with a ring-shaped fixing member to each other; and detaching the holder from the first blood vessel when they are fixed by the fixing member or after they are fixed. The end-to-side blood vessel anastomosis method can readily open the dissected portion on the side of the blood vessel upon end-to-side blood vessel anastomosis and retain it in that state. No foreign matter is present within the blood vessel after completion of the anastomosis.
