Abstract
We prospectively compared sequential portal-arterial revascularization (SPAr, group 1 no. 19) versus contemporaneous portal-hepatic artery revascularization (CPAr, group 2 no. 21) in 40 consecutive liver transplantation (LT). There were no differences in the demographics characteristics, MELD score, indication to LT, and donor's parameters between the two groups. CPAr had longer warm ischemia 66 ± 8 versus 37 ± 7 min (P < .001), while SPAr had longer arterial ischemia 103 ± 42 min (P = .0004). One-year patient's and graft survival were, respectively, 89% and 95% versus 94% and 100% (P = .29). At median followup of 13 ± 6 versus 14 ± 7 months biliary complications were anastomotic stenosis in 15% versus 19% (P = .78), and intrahepatic nonanastomotic biliary strictures in 26% versus none (P = .01), respectively, in SPAr and CPAr. CPAr reduces the incidence of intrahepatic biliary strictures by decreasing the duration of arterial ischemia.
