Portal vein arterialization (PVA) is a technical variation of auxiliary heterotopic liver transplantation (AHLT) that is rarely studied but that simplifies the AHLT surgical technique because it does not act on the portal area. The objective of this study was to analyze the hemodynamic consequences of this auxiliary transplant in an experimental model. ⋯ Heterotopic liver transplantation with portal arterialization is well-tolerated hemodynamically. Graft reperfusion decreases SVRI and increases CI to compensate for this. This behavior, which in healthy recipients like ours is not a problem, could imply a contraindication in patients with a prior hyperdynamic state.
