Background/Objectives: Back wall technique is usually used for hepatic artery
anastomosis in living donor liver-transplantation. In this technique, two stitches are placed
in the two corners of the artery wall initially and the microclamp on the artery is rotated to
place the sutures to the back wall first. In some cases, the microclamp cannot be rotated
because of insufficient length of the graft or recipient artery. If this occurs, it may be difficult
to rotate the artery to perform the back wall artery anastomosis technique. In these cases, the
difficulty of performing the anastomosis can cause intimal tears. Thus, we prefer a modified
technique for artery anastomosis in such situations.
Methods: In this modified technique, two stitches are placed in the middle of the posterior
wall and middle of the anterior wall initially. The artery is twisted 90
to the right side and
to the left side respectively, instead of one 180
rotation, to place the back wall stitches.
Conclusion: In this modified technique, reversing the microclamp is eliminated that can cause
intimal damage. Therefore, it may be superior to the conventional method in terms of reducing
the difficulty of performing anastomosis and intimal damage to the vessels.
