Core Tip

Core Tip: Guaranteeing adequate graft perfusion is essential to obtain optimal outcomes after liver transplantation (LT). This retrospective single-center study analyzed 25 cases of portal vein arterialization (PVA) for portal flow optimization in LT. To account for the time-sensitive effect, cases were classified into two groups: prereperfusion (pre-PVA) if the arterioportal anastomosis was performed before graft revascularization and postreperfusion (post-PVA) if PVA was performed afterward. We found that pre-PVA yields better results than post-PVA and that hyperperfusion could play a protective role against graft dysfunction. Currently, this is the largest case series studying PVA during LT.
