Segmental volumetry and metastatic lesions mapping
*GP - glissonean pedicle
Fig. 1. Liver CT mapping of patient S.’s metastatic lesions . A – 3D segmentation and volumetry with metastatic disease mapping, parenchymal transection lines. B and C – CT data in the axial plane. R1v is the zone of vascular contact of one of the metastatic lesion in S8/S1. T – metastatic lesions. GP8v/8d – glissonean pedicles for ventral and dorsal portions of S8 respectively. IVC – inferior vena cava. RHV – right hepatic vein.
Fig. 2. Computer tomography data of CRC metastatic lesion spread of patient S. on the dorsal part of S1d and schematic representation of the anatomy of S1 (SIX: dorsal and caudal parts of the segment) [7].
Fig. 3. Picture and ultrasound data of patient S. MHV – median hepatic vein without signs of invasion, contacting at a distance of 3 cm on the ≤ ½ semicircle to the metastatic focus (blue arrows); T – metastatic focus with vascular contact (white arrows).
Fig. 4. Intraoperative pictures of patient 1,2,3,4 - view after parenchymal transsection and removal of the specimen (S5 and S8v preserved). 5,6 - gross specimen (S6, S7, S8d and S1d) with 9 metastatic lesions. On picture 4, the arrows of the IVC after the completion of “Piggy back” and the skeletonized terminal segment of the MHV are indicated.
