Impact of PVE on Patient's Long-term Survival, Complications and Cancer Recurrence.

"Portal vein embolization (PVE) is a procedure that induces regrowth on one side of the liver in advance of a planned hepatic resection on the other side. The procedure is frequently used in primary liver cancer (hepatocellular carcinoma) and colorectal liver metastases.~An interventional radiologist will place a needle percutaneously (through the skin) into the liver and identify the blood vessel on the side where the largest part of the tumor is being supplied. Tiny microspheres are then infused into the portal vein which supplies blood to the area, embolizing it by cutting off its blood supply.~This blockade of the blood supply induces the other side of the liver to regrow. After several weeks, the non-embolized side has grown enough so that surgery is now a viable option.~Source of this information : http://general.surgery.ucsf.edu/conditions--procedures/portal-vein-embolization-(pve).aspx"
