Preoperative morphometric measurements of liver vasculature to predict postoperative liver failure: bicentric study.

Abstract

Patients that require major liver resection for various hepatic diseases have a high risk of postoperative liver failure if the remaining postoperative liver is not adequate. Preoperative volumetry of the future liver remnant is not a strong predictor of postoperative liver failure, as function does not always correlate with volume. Our study proposed a new indicator of postoperative liver failure based on preoperative ratio of the diameter of the portal vein (inflow) and the hepatic vein (outflow), which are more predictive of postoperative liver failure than standard volumetry.
