Relevance. To evaluate the effectiveness of X-ray endovascular embolization of the portal vein branch in terms of preparation for extensive liver resections. Materials and methods. A retrospective analysis of 74 right-sided hemihepatectomies performed in one stage (classical, n = 54) or in two stages (X-ray endovascular embolization of the right portal vein followed by liver resection was performed, n = 20).Results. X-ray endovascular embolization of the right portal vein was accompanied by a significant increase in the planned liver remainder by an average of 37.3 %. This made it possible to reduce the volume of intraoperative blood loss, the incidence of postresection hepatic failure from 43.1 to 15.9 %, and postoperative mortality from 9.3 to 5.0 %.Conclusions. Preoperative X-ray endovascular embolization of the right portal vein leads to vicarious enlargement of the left lobe of the liver. This makes it possible to reliably reduce the incidence of post-resection hepatic failure after right-sided hemihepatectomy and, accordingly, reduce the frequency of deaths. |
