ALPPS procedure in the present patient. Panel a shows the scheme of parenchymal division at the umbilical fissure (blue line) following 3 partial resections within the left lateral section (black dotted line). Panel b shows territories of S4 portal pedicles (green area) and MHV (blue area) as depicted by 3-dimensional (3D) computed tomography. The resection line at the left umbilical fissure is shown in yellow. Panel c shows an additional line of resection to excise the territories of both S4 and the MHV (in blue). Dotted lines indicate 3 partial resections and the resection line at the umbilical fissure. Panel d shows a 3D-CT image with the line for additional resection of S4 and the MHV territory in yellow
