摘      要：BACKGROUND Portal vein arterialization(PVA)has been used in liver transplantation(LT)to maximize oxygen delivery when arterial circulation is compromised or has been used as an alternative reperfusion technique for complex portal vein thrombosis(PVT).The effect of PVA on portal perfusion and primary graft dysfunction(PGD)has not been *** patients receiving PVA and LT at the Fundacion Santa Fe de Bogota between 2011 and 2022 were *** account for the time-sensitive effects of graft perfusion,patients 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 *** pre-PVA rationale contemplated poor portal hemodynamics,severe vascular steal,or ***-PVA was considered if graft hypoperfusion became *** interventions were attempted before PVA.
