Comparative Study of Portal Vein Embolization Versus Portal Vein Ligation for Induction of Hypertrophy of the Future Liver Remnant Using a Mini-Pig Model

Both PVL and PVE are able to induce hypertrophy of the future liver remnant. In comparison, PVE is the more effective technique to increase the future liver remnant. This is due to a more effective, durable occlusion of the portal branches. Formation of collaterals between occluded and nonoccluded liver parts seems to be the cause of inferior regeneration in the ligation group.
