What is portal vein embolization?

Portal vein embolization (PVE) is a procedure performed by Interventional Radiologists (IR). IRs are board-certified physicians who specialize in minimally invasive targeted treatments to treat medical conditions all over the body. The portal vein receives venous blood from the stomach and intestines and delivers it to the liver. For some patients who have a tumor of the liver which will require surgical removal, PVE may be necessary. Embolization is a procedure that cuts off the flow of blood into an area that it previously supplied. The liver has 2 main lobes. PVE blocks the flow of portal vein blood to a particular lobe of your liver which contains a tumor causing it to get smaller, while the other healthy lobe enlarges to make the surgery safer for the patient. Usually the surgery is performed 3-4 weeks after the PVE procedure.
