Portal Vein Embolization
If the tumor has metastasized (moved) to only one part of the liver, surgeons may be able to remove the affected part of the liver if there will be enough normal liver left behind. If there is not be enough liver left behind, we can encourage the normal liver to grow by blocking a portion of the portal vein from the inside, diverting blood from the abnormal liver to the normal liver.
Under ultrasound and x-ray guidance, a needle is introduced through belly and liver into the portal vein. Catheters and wires are introduced into the portal vein. Portions of the vein are blocked from the inside with various agents such as plastic beads and coils or even glue. All wires and catheters are then removed.
The procedure has a mild to moderate risk of bleeding, infection, and damage to nearby organs. All patients should refrain from eating and drinking for 6 hours prior to the procedure and will undergo general anesthesia (i.e be put to sleep). Finally, all patients remain in the hospital overnight after their procedure.
