To evaluate correlation between growth rate of left portal vein (LPV) and future liver remnant (FLR) after right portal vein embolization (PVE), and to design models predicting FLR growth rate and volume using LPV area measurements on computed tomography (CT).
Methods
A total of 134 patients (59.6 ± 10.2 years; 103 men) who underwent right PVE with contrast‐enhanced CT before and 3–5 weeks after PVE were retrospectively identified. Kinetic hypertrophy ratio (KHR) and kinetic degree of hypertrophy (KDH) served as growth rate parameters. Correlations between LPV growth rate and FLR growth rate and volume change were evaluated by linear regression analysis. The agreements between actual volumetrically determined growth rates and volume of FLR and those estimated from regression equation using LPV measurements were assessed by Bland–Altman plots.
Results
Growth rates of LPV and FLR correlated significantly (P |

To evaluate correlation between growth rate of left portal vein (LPV) and future liver remnant (FLR) after right portal vein embolization (PVE), and to design models predicting FLR growth rate and volume using LPV area measurements on computed tomography (CT).
Methods
A total of 134 patients (59.6 ± 10.2 years; 103 men) who underwent right PVE with contrast‐enhanced CT before and 3–5 weeks after PVE were retrospectively identified. Kinetic hypertrophy ratio (KHR) and kinetic degree of hypertrophy (KDH) served as growth rate parameters. Correlations between LPV growth rate and FLR growth rate and volume change were evaluated by linear regression analysis. The agreements between actual volumetrically determined growth rates and volume of FLR and those estimated from regression equation using LPV measurements were assessed by Bland–Altman plots.
Results
Growth rates of LPV and FLR correlated significantly (P < 0.001). The mean difference between actual and estimated value was 0.1% for KHR‐FLR (actual, 9.5 ± 6.0%; estimated, 9.4 ± 3.8%), 0.0% for KDH‐FLR (actual, 3.3 ± 1.4%; estimated, 3.3 ± 0.7%), −3.8 cm3 for FLR volume (actual, 642.5 ± 167.8 cm3; estimated, 646.4 ± 156.5 cm3), and −0.1% for proportion of FLR volume (actual, 48.7 ± 7.8%; estimated, 48.9 ± 7.8%).
Conclusions
After right PVE, FLR growth rate and volume can be simply estimated from the change in LPV area.
Highlight
Park and colleagues showed that the volume and growth rate of the future liver remnant after right portal vein embolization can be readily estimated on the basis of baseline volumetric profiles and computed tomography‐based measurement of the portal vein area without dedicated volumetric software or multiple measurements of liver volume.</description><identifier>ISSN: 1868-6974</identifier><identifier>EISSN: 1868-6982</identifier><identifier>DOI: 10.1002/jhbp.633</identifier><identifier>PMID: 31070855</identifier><language>eng</language><publisher>Japan: Wiley Subscription Services, Inc</publisher><subject>Adult ; Aged ; Contrast Media ; Decision support model ; Embolization ; Embolization, Therapeutic ; Female ; Growth rate ; Humans ; Hypertrophy ; Liver - diagnostic imaging ; Liver - pathology ; Liver Diseases - diagnostic imaging ; Liver Diseases - pathology ; Liver Diseases - therapy ; Liver regeneration ; Male ; Middle Aged ; Multidetector computed tomography ; Organ Size ; Portal Vein - diagnostic imaging ; Portal Vein - pathology ; Portal vein embolization ; Retrospective Studies ; Tomography, X-Ray Computed</subject><ispartof>Journal of hepato-biliary-pancreatic sciences, 2019-07, Vol.26 (7), p.300-309</ispartof><rights>2019 Japanese Society of Hepato‐Biliary‐Pancreatic Surgery</rights><rights>2019 Japanese Society of Hepato-Biliary-Pancreatic Surgery.</rights><rights>Copyright © 2019 Japanese Society of Hepato‐Biliary‐Pancreatic Surgery</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c3733-beb1d32c8e9398797360ffec939d04f7235580f629f1788255033fbdbbbb1c53</citedby><cites>FETCH-LOGICAL-c3733-beb1d32c8e9398797360ffec939d04f7235580f629f1788255033fbdbbbb1c53</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,776,780,27898,27899</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/31070855$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Park, Hyo Jung</creatorcontrib><creatorcontrib>Kim, Kyoung Won</creatorcontrib><creatorcontrib>Choi, Sang Hyun</creatorcontrib><creatorcontrib>Lee, Jeongjin</creatorcontrib><creatorcontrib>Kwon, Heon‐Ju</creatorcontrib><creatorcontrib>Kwon, Jae Hyun</creatorcontrib><creatorcontrib>Song, Gi‐Won</creatorcontrib><creatorcontrib>Lee, Sung‐Gyu</creatorcontrib><title>Dilatation of left portal vein after right portal vein embolization: a simple estimation for growth of future liver remnant</title><title>Journal of hepato-biliary-pancreatic sciences</title><addtitle>J Hepatobiliary Pancreat Sci</addtitle><description>Background
