Background: Technical problems such as graft and vascular size are more common in living donor liver transplantation (LDLT) than in deceased donor liver transplantation. It is usually possible to get enough length of vessels on the graft, but the opposite situation is devastating. Finding the suitable vessel graft is life-saving in those situations. In this paper we present a case of gonodal vein interpositioning for hepatic artery reconstruction in an LDLT recipient. To the best of our knowledge, this is the first such case to be reported in the literature.
Case Report: A 36-year-old man with cirrhosis secondary to hepatitis B underwent LDLT. Within minutes after completing the anastomosis, the artery was thrombosed. Disrupting the anastomosis showed subintimal dissection of the recipient right hepatic artery extending to the gastro-duodenal junction. A 4 cm segment of gonodal vein, which matched the diameter of the recipient hepatic artery, was used as a bridge. The patient’s postoperative recovery was excellent and Doppler ultrasonography demonstrated sufficient hepatic arterial blood flow. At long-term follow-up (18th months), the patient’s graft is still functioning.
Conclusions: Gonodal vein interposition for hepatic artery reconstruction in living donor liver transplantation has not been previously reported. In light of the urgency of this situation, we believe it can be a life-saving reconstruction.
