In certain patients with primary or metastatic liver cancer, liver transplantation may not be an option, and surgical resection and/or tumor ablation may be the only solutions. However, removing too much liver tissue may result in life-threatening liver failure. Therefore, a procedure can be performed prior to liver resection or ablation in order to promote liver regeneration and growth in non-diseased liver segments. This is accomplished by "starving" and shrinking the diseased segment of liver, while sparing viable liver and improving the success of surgery and patient recovery. This can be performed both as inpatient and outpatient procedures by the interventional oncologist.
