Selective portal vein embolization: theoretical basis and clinical application / 临床肝胆病杂志

ABSTRACT

At present,partial hepatolobectomy remains the preferred and most effective treatment method for primary or metastatic malignant liver tumors,but a low future liver remnant (FLR) volume after surgery is the main risk factor for liver failure and may affect patients'prognosis.Through the embolization of the tumor-bearing portal vein branch,selective portal vein embolization (PVE) redistributes the portal vein blood flow and increases portal vein blood flow in the contralateral liver tissue to increase the FLR volume.This article reviews the theoretical basis and clinical application of selective PVE.As an adjuvant therapy before hepatectomy,selective PVE can reduce the incidence rate of postoperative liver failure,increase tumor resection rate and surgical safety,and create the chance for surgery in patients who cannot undergo surgical treatment.
