Reverse portal flow after liver transplantation--ominous or acceptable?

Reversal of portal flow or hepatofugal flow after liver transplantation is a rare complication after liver transplantation. The available reports in the literature suggest that it is an ominous condition that requires immediate operative intervention, failing which prognosis would be grim. We report two children from two different centers who developed hepatofugal flow in the immediate post-operative period after liver transplantation. The possible etiologies in these patients were acute rejection in one and absence of an MHV causing inadequate hepatic venous outflow in the other. Both patients were treated non-operatively with steroids and immunosuppression. Spontaneous reversal to a normal hepatopetal flow occurred in both and the patients continue to be well six months after the transplant. Our experience contradicts the viewpoint that hepatofugal flow equates to mortality in the absence of surgical intervention. It remains to be defined as to which patients with hepatofugal flow will benefit from surgical intervention. Copyright (c) 2009 Wiley Periodicals, Inc.
