By-pass operation leads to reconfiguration of blood vessel wall. Growth deforma t ion gradient through stress potential in the restructuring of blood vessel was p roposed and a numerical example was given. The results indicate that at the begi nning of reconfiguration, stress in the blood vessel wall changes sharply, the c ircumferential length and the thickness grow rapidly, the changes of stress dist ribution and geometry size are gradually reduced, and the increment of thickness is gradually slowed down. This proves that stress leads to the reconfiguration of the blood vessel.
