[Preoperative liver venous deprivation]

Some hepato-biliary cancers require major liver resections. Post hepatectomy liver failure is a complication that occurs when the remnant liver cannot maintain its synthetic and excretory functions. To overcome this issue, portal vein embolization has been developed to induce future remnant liver hypertrophy preoperatively. However, up to 20% of patients cannot proceed to the hepatectomy due to insufficient hypertrophy or tumor progression in the interval between the embolization and the planned surgery. Liver venous deprivation (LVD) is a technique that combine ipsilateral portal and hepatic vein embolization. With this technique, the hypertrophy seems to be faster and more important, with low complications rate and no mortality associated with the procedure.
