Preliminary results on simultaneous portal and hepatic vein embolization prior to major hepatectomy

Introduction Portal vein embolization (PVE) has been standard procedure for hypertrophy of future remnant liver (FRL) prior to major hepatectomies. However, tumor progress might limit surgery if rapid hypertrophy is not assured. Additional hepatic vein embolization (HVE) obstructs outflow pathway, inhibiting arterial flow and induces further damage to embolized liver area and thereby fosters regeneration of contralateral liver.
