Abstract
Liver resection can be curative in a select group of patients with primary and secondary hepatobiliary malignancies.[1] For these patients, the size and function of the future liver remnant (FLR) must be carefully considered to limit the potential for posthepatectomy liver failure (PHLF), a predominant cause of mortality.[1] [2] [3] [4] Preoperative portal vein embolization (PVE) has been shown to increase the volume of the FLR, allowing more patients to become surgical candidates and improving postoperative outcomes.[1] [2] [5] [6] [7] PVE occludes the portal venous branches supplying the lobe of the liver to be resected and redirects blood flow toward the FLR, leading to compensatory hypertrophy.[2] [8]
