(a) Typical liver lesion/tumours amenable to MMH. The CT demonstrates a typical lesion that would be considered for MMH. The mass is within 4 cm of the MHV origin with no invasion of the RHV and LHV (ai). As demonstrated in (aii) there is no compromise to the hepatic inflow. (b) Post-operative cross-sectional imaging following MMH. The CT images demonstrate the post-operative appearances in a patient following MMH. The image on the left shows resection of the MHV at the IVC with preservation of the RHV and LHV, a preserved V7 branch to the RHV can be seen (bi). The transection plane is keep superior to the liver hilum (top right) and anterior to the RHV (bottom left) (bii). (c) OS for patients undergoing MMH.
