title: Outcome in right living related liver transplantation with branch-patch arterial reconstruction.
abstract: cRight lobe living liver transplantation is being performed worldwide with increased frequency. Difficult arterial reconstructions are often encountered because of small diameter or discrepancy between arterial stumps. The risk of arterial thrombosis is reported as high as 26%: microsurgical techniques have reduced this rate below 2%, increasing warm ischemia time. We have developed a new branch patch technique in living related liver transplantation using the donor cystic artery to create an enlarged patch anastomosis that enables increase in the vessel's diameter and therefore greater inflow to the liver. We have followed 8 patients treated with this technique. After more than 1 year (mean follow-up: 636 days) we did not observe any arterial thrombosis by Doppler ultrasound performed every 3 months. The mean resistance index was 0.68 (0.57-0.83-). Three patients died with functional graft without signs of thrombosis. We believe that the cystic artery branch patch technique is feasible in all cases. It is fast (mean time: 6.2 min), it allows a shorter warm ischemia time, and there is no increased risk of thrombosis.
