Résumé
Variations in graft arterial anatomy can increase the risk of postoperative hepatic arterial thrombosis (HAT), especially in presence of a replaced or accessory right hepatic artery (RHA). We retrospectively analyzed 223 cases of liver transplantations with the presence of an RHA on the graft. Patient outcomes were compared according to the four different reconstruction methods used: (i) the re-implantation of the RHA into the splenic or gastroduodenal artery (n = 106); (ii) the interposition of the superior mesenteric artery (SMA) (n = 83); (iii) dual anastomosis (n = 24); (iv) use of an aortic patch including the origins of both the SMA and the coeliac trunk (n = 10). A competing risk analysis and Inverse Probability Weighting (IPW) were used. We found that the interposition of the SMA method was associated with a significantly lower incidence of HAT, at 4.8% compared to the re-implantation method at 17.9%, dual anastomosis at 12.5%, and aortic patch at 20%, p = .03. In the competing risk analysis with IPW, the only risk factor for RHA thrombosis was the type of reconstruction. Taking the SMA interposition group as the reference, the sub-hazard ratio (sHR) was 5.05 (CI 95 [1.72; 14.78], p < .01) for the re-implantation group, sHR = 2.37 (CI 95 [0.51; 11.09], p = .27) for the dual anastomosis group and sHR = 2.24 (CI 95 [0.35; 14.33], p = .40) for the aortic patch group. There were no differences for intraoperative transfusion, hospitalization duration (p = .37) or incidence of severe complications (p = .1). The long-term graft (p = .69) and patient (p = .52) survival was not different. In conclusion, the SMA interposition method was associated with a lower incidence of RHA thrombosis.
