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.
