Polyvinyl alcohol (PVA) particles are used for the embolization of various vascular tumors. They are also used before hepatic resection to embolize the ipsilateral portal vein, causing hypertrophy of the remaining liver. We report our first experience with portal vein embolization (PVE) with PVA particles to treat gastric cancer metastasis to the liver. PVE with PVA is a safe interventional radiologic procedure, which does not cause problems during surgery and can improve the outcome of hepatic resection.
