Abstract Hepatocellular carcinoma (HCC) is one of the most common primary liver neoplasms worldwide with poor prognosis.In most cases, hepatic resection is considered to be the optimal treatment of HCC, however, the majority of patients with HCC are not candidates for resection because of the tumour size, tumour location near main bile ducts precluding a margin-negative resection, or inadequate hepatic function related to coexistent cirrhosis.Thermal ablation, including radiofrequency ablation (RFA) and microwave ablation (MWA), have been shown to be effective for treating HCC.The goal of thermal ablation is to heat malignant tissues to temperatures that can induce immediate coagulative necrosis.Microwave ablation (MWA), a thermal ablative technique that has recently emerged as a new therapeutic option, affording the capacity to perform larger and faster ablations that even exceed the limitations of radiofrequency ablation (RFA).Percutaneous MW ablation can be performed using ultrasound and/or CT for imaging guidance.Ultrasound has the advantage of real-time guidance for targeting, applicator placement and monitoring the development of the ablation zone.The patient safety, absence of procedure-related major complications and mortality as well as the low incidence of local recurrence makes it safe and effective in the treatment of hepatocellular carcinoma. |
