ABSTRACT
In the past when liver resection carried significant mortality and morbidity rates, local ablative techniques were developed to attempt local control of disease. The survival benefit following resection of liver metastases has led to a renewed emphasis to identify methods to treat patients with unresectable liver lesions. Chemoembolization, arterial infusion therapy, and local ablation techniques have all been employed. Of these techniques, local thermal ablative methods have produced the most interest in recent years.
