Doubly-armed short sutures are useful for microsurgical hepatic artery reconstruction in living-related liver transplantation

Although microsurgical hepatic artery reconstruction has become the essential technique in pediatric and living-related liver transplantation, it remains a technical challenge. We describe here our microsurgical hepatic artery reconstruction technique in living-related liver transplantation using a doubly-armed short suture. From August 1998 to March 1999, 8 patients underwent living-related liver transplantation at the Kyushu University. For these 8 patients, microsurgical reconstruction with doubly-armed short sutures were undertaken. After preparing the operative field for microsurgery, operative microscopy with a continuous zoom magnification is introduced. Interrupted sutures using doubly-armed short sutures are performed in a biangular stay-sutured method with a double clip. None of the 8 patients developed hepatic artery thrombosis. We conclude that the use of doubly-armed sutures allows safe and reliable in microsurgical hepatic artery reconstruction in living related liver transplantation.
