Portal vein embolization

Portal vein embolization (pronunciation: por-tal vayn em-bo-li-za-shun) is a medical procedure used to increase the size of the liver segment that will remain after liver resection. The procedure involves the intentional blockage of the portal vein to one part of the liver, causing that part to shrink and the other part to grow.

Etymology

The term "portal vein embolization" is derived from the following words: "portal" (from Latin porta meaning "gate"), "vein" (from Old English fena meaning "channel"), "embolization" (from Greek embolos meaning "stopper or piston").

Procedure

Portal vein embolization is performed by a radiologist using imaging guidance. The procedure involves the injection of a substance into the portal vein to block the blood flow to the part of the liver that will be removed. This causes the remaining part of the liver to increase in size, which can help to prevent liver failure after surgery.
