Portal vein embolization (PVE) may be performed before hemihepatectomy to increase the volume of future liver remnant (FLR) and to reduce the risk of postoperative liver insufficiency. We report the case of a 71-year-old patient with hilar cholangiocarcinoma undergoing PVE with access from the right portal vein using a mixture of n-butyl-2-cyanoacrylate and ethiodized oil. During the procedure, nontarget embolization of the left portal vein occurred. An aspiration maneuver of the polymerized plug failed; however, the embolus obstructing portal venous flow in the FLR was successfully relocated into the right portal vein while carefully bypassing the plug with a balloon catheter, inflating the balloon, and pulling the plug into the main right portal vein.
门静脉栓塞术（PVE）可在半肝切除术前进行，以增加未来肝余体积（FLR）并降低术后肝衰竭的风险。我们报告了一例71岁肝门部胆管癌患者接受PVE的病例，通过右门静脉使用氰基丙烯酸正丁酯和乙碘油的混合物进行穿刺。术中发生了左门静脉的非靶栓塞。对聚合栓子的抽吸操作失败；然而，通过用球囊导管小心绕过栓子、充盈球囊并将栓子拉入主右门静脉，成功地将阻塞FLR门静脉血流的栓子重新定位到右门静脉。
