Introduction:
In living donor liver transplantation (LDLT), hepatic arterial continuity is crucial to avoid biliary leakage, biliary stricture, cholangitis, and graft and patient loss. Sometimes there exist factors making anastomosis difficult or even impossible. In these cases, a vascular graft may be needed to bridge the two arteries for revascularization.
Method:
Medical records of 297 patients who underwent LDLT between June 2000 and July 2016 at the Hepatopancreatobiliary Surgery and Liver Transplantation Unit of Dokuz Eylul University Hospital were reviewed retrospectively. Twenty-eight (9%) patients younger than the age of 18 were excluded from the study. The remaining 269 patients were included in the study. We analyzed data of patients who developed hepatic arterial complications during or after LDLT and underwent revascularization using autologous interposed inferior mesenteric artery (IMA) grafts.
Results:
In 8 (2.9%) of the 269 patients who underwent LDLT and were included in the study, autologous interposed IMA grafts were used for the hepatic artery revascularization. All of the patients were males. Their mean age was 42 (range, 25-57). The mean duration of follow-up was 83.25 months (range, 3-144 months). One patient developed intraoperative hepatic arterial thrombosis (HAT) after autologus IMA reconstruction and this patient needed retransplantation. No arterial complications developed in the other 7 patients.
Conclusion:
Autologous interposed IMA graft could be used as an alternative vascular graft in hepatic artery revascularization to provide tension-free hepatic arterial continuity.
