Abstract

Small-for-size syndrome occurs in the presence of a reduced mass of liver that is insufficient to maintain normal liver function. It has been speculated that this dysfunction is principally associated with graft exposure to excessive portal perfusion. The aim of these cases was to evaluate the efficacy of octreotide, a splanchnic vasoconstrictor, and esmolol, a selective beta-blocker, to modify the portal perfusion in the postoperative phase after left living related liver transplantation (LRLT). Four patients who underwent left LRLT with graft-to-recipient weight ratios of 0.60 +/- 0.24 were studied with a catheter placed in a jejunal vein. We observed high basal values of hepatic venous pressure gradient (HVPG) and portal vein flow (PVF). Octreotide infusion decreased HVPG, an effect that was more pronounced when it was combined with esmolol. The administration of both drugs was also associated with an improvement in portal vein oxygen saturation. Despite variation in PVF, the plasma disappearance rate of indocyanin green did not change during the infusion of the two drugs. In conclusion, octreotide and esmolol infusion allowed a manipulation of portal vein pressure that should be measured in left LRLT using a small-for-size graft.
