Major hepatic resections are often required for the treatment of primary and secondary hepatic malignancies. A key step in planning a major hepatectomy is predicting the risk of PHLF. It is generally accepted that a postoperative liver remnant volume of 25% or greater is sufficient to minimize the risk of PHLF in a healthy liver.1 However, this method is incapable of determining a subtle decrement in baseline hepatic function. This is a significant limitation in patients with cirrhosis or chemotherapy-induced steatohepatitis. To augment volumetric analysis, functional tests such as indocyanine green excretion are under investigation for their role as a predictor of PHLF.2
