Background The aim of the present study was to evaluate the liver function in the congestive area of the remnant liver after hemi-hepatectomy with middle hepatic vein (MHV) resection for liver cancers. %26lt;br%26gt;Methods From November 2009 through December 2012, 18 patients underwent hemi-hepatectomy including the MHV for liver cancers. Post-hepatectomy, the volume of the congestive area, which appeared as a hyper-intense area on T2-weighted images and dysfunctional area, which appeared as a low intensity area on hepatobiliary phase images in the remnant liver was evaluated in all patients by gadoxetic acid disodium-enhanced magnetic resonance imaging. %26lt;br%26gt;Results Fifteen of 18 patients showed a congestive area, and 16 of 18 patients showed a dysfunctional area in the remnant liver. The dysfunctional rate (median 11%) was significantly larger than the congestive rate (median 5%, P = 0.0004). The dysfunctional rate was associated with tumor invasion to the root of the MHV, and no tumor invasion to the root of the MHV was identified as a significant predictor of a larger dysfunctional area (odds ratio 25.888, P = 0.0267) on multivariate analysis. %26lt;br%26gt;Conclusion Hemi-hepatectomy with MHV resection for liver cancers should be performed considering the dysfunctional area in the remnant liver, which is associated with tumor invasion to the root of the MHV.
