[Portal vein stenting as a bridge to chemotherapy for perihilar cancer with portal vein stenosis - a case report].

The stenting strategy for portal vein stenosis in cases with unresectable hilar malignancies reduces portal hypertension and maintains portal vein blood flow. This not only improves quality of life, but also leads to aggressive therapy with anticancer agents. A 65-year-old woman presented with painless jaundice 8 months after left hemihepatectomy with lymph node dissection for intrahepatic cholangiocellular carcinoma. Seven months after biliary stenting for bile duct stenosis, progressing pancytopenia and ascites were noted. Imaging studies revealed portal vein stenosis by the tumor at the hepatic hilum. Percutaneous transhepatic portal vein stent placement was performed, and pancytopenia and ascites improved immediately thereafter. Chemotherapy for recurrence of intrahepatic cholangiocellular carcinoma at the hepatic hilum has been initiated, and the patient has been alive 15 months since.
