Preoperative portal vein embolization

Preoperative portal vein embolization (PVE)

PVE is an image-guided procedure performed prior to resection of liver malignancies to increase the size of the future liver remnant (FLR) or the liver segments that will remain after surgery. By embolizing the portal vein branches supplying the tumor-bearing segments, flow is redirected to the non–tumor-bearing segments, resulting in hypertrophy of the FLR.
