Ipsilateral Hepatic Vein Embolization After Portal Vein Embolization

Portal vein embolization (PVE) induces shrinkage of the embolized lobe and compensatory enlargement of the non-embolized lobe, but it does not always induce sufficient liver regeneration. There was no effective method to accelerate liver regeneration in addition to PVE yet. This study intends to assess the effect of ipsilateral hepatic vein embolization (HVE) performed after Portal vein embolization (PVE) on liver regeneration. During a 1-year study period, preoperative HVE would be performed on 10 or more patients who had shown limited liver regeneration after PVE awaiting right hepatectomy. Sequential application of PVE and HVE may be safe and effective in facilitating contralateral liver regeneration by inducing more severe liver damage than PVE alone.
