Kohno S, Isoda h, Ono A, et al. - The relationships between the radiologic findings and the future liver remnant hypertrophy ratio for 79 individuals who underwent portal vein embolization of the right branch between July 2007 and April 2017 were retrospectively investigated in order to assess the radiologic findings prognosticating the future liver remnant hypertrophy ratio following portal vein embolization of the right branch. Between the future liver remnant hypertrophy ratio and the number of proximal small branches from the right anterior and posterior portal veins, transient hepatic parenchymal enhancement, portal vein invasion, and variants of main portal vein anatomy, statistically important correlations were discovered. In individuals without the radiologic findings exhibiting statistically important variations and in those with at least one important finding, the mean future liver remnant hypertrophy rate was 51.0% (n = 16) and 25.8% (n = 63), respectively. In conclusion, when added to formerly reported factors, the radiologic findings recognized could aid to ascertain the indications for portal vein embolization and novel approaches for major hepatectomy.
