ICGR15 measurements for liver function assessment during hemi-hepatectomy. Note: Figure illustrated the use of indocyanine green retention rate at 15 min (ICGR15) to evaluate liver function at different stages in hemi-hepatectomy procedure. A Pre-hepatectomy measurement of total liver function. B Intra-hepatectomy measurement with occlusion of the hemi-hepatic pedicle, representing predicting remnant liver function. Shows demarcation (ischemic) line and occlusion point. C: Post-hepatectomy measurement of final remnant liver function after hemi-hepatectomy
