  • Title: Cavoportal hemitransposition for unrecognized spontaneous mesocaval shunt after liver transplantation: a case report.
    Author: Chmurowicz T, Zasada-Cedro K, Wojcicki M.
    Journal: Transpl Int; 2013 Jun; 26(6):E46-9. PubMed ID: 23506649.
    Abstract:
    Spontaneous portosystemic shunts can steal the blood away from the portal system. This may result in graft dysfunction or even loss following liver transplantation and can be sorted by shunt occlusion based on intraoperative flow measurements. Herein, we present an alternative technique with cavoportal hemitransposition performed for unrecognized spontaneous mesocaval shunt with 'portal steal' syndrome and primary graft nonfunction diagnosed first day following the transplant. This was chosen as a rescue strategy because an attempt to locate the shunt during relaparotomy was unsuccessful. As there was no improvement, emergency liver retransplantation with preservation of the cavoportal hemitransposition was performed on the fourth day after the primary transplant with good long-term outcome. We conclude that cavoportal hemitransposition during or after liver transplantation can be used to provide an adequate inflow into the donor portal vein if the shunting vessels responsible for the steal cannot be located and dealt with at surgery.
