[Combined hepatic resection and removal of portal vein tumor thrombi].

Portal thrombectomy with extended hepatectomy for extensively progressive primary liver cancer (Vp 3), in which the tumor thrombus has spread beyond the first portal branches, will make other non-surgical treatments possible and improve patients quality of life. We have performed extensive resections in 15 cases of such Vp 3 liver cancer. One patient with huge HCC involving retrohepatic IVC underwent in situ extended left hepatectomy without reconstruction of IVC, resulting in postoperative renal failure because of thrombosis in the bilateral renal veins, but 14 other patients' postoperative courses were uneventful. Ten of 14 patients relapsed within one year, but these patients underwent non-surgical treatments, resulting in improvement in the quality of life. The 1-, and 3-year survival rates were 55.6% and 32.5%, respectively.
