[Percutaneous transhepatic portography in patients with hepatocellular carcinoma: percutaneous transhepatic portal venous embolization].
Percutaneous transhepatic portography was performed in 28 patients with HCC and PTPE was attempted in 9 of them. Displacement of the portal vein was found in 37% of 52 HCCs. Other portographic findings were: encasement (19%), avascular area (19%), occlusion (10%), narrowing (4%), neovascularization (4%), tumor staining (2%). Frequency of the tumor-related portography findings was found to be increased in relation to tumor size. TAE followed by PTPE with stainless steel coil (6 cases) or microcapsule form of MMC (3 cases) was performed on 9 cases. PTPE appears to be a promising adjuvant to conventional TAE.
