When is enough enough?-predicting adequacy of portal vein embolization for hypertrophy of the future liver remnant in the age of liver venous deprivation.

The median (interquartile range) pre-portal vein embolization sFLR was 22% (16-29%).

Out of 477 patients, 284 (60%) achieved sFLR ≥30%, 271 (57%) achieved kinetic growth rate ≥2% per week, and 364 (76%) achieved at least one of the two.

Multiple logistic regression showed that higher pre-portal vein embolization sFLR [odds ratio (OR), 1.4; 95% confidence interval (CI): 1.31-1.49] and extended portal vein embolization (OR, 0.47; 95% CI: 0.25-0.87) were predictive of post-portal vein embolization sFLR ≥30%.
