Radiofrequency (RF) and microwave ablation are minimally invasive procedures used to treat liver tumors. Both procedures involve the insertion of a thin, needle-like device through the skin and into the tumor, where high-frequency electrical energy is used to heat and destroy the tumor cells.
RF ablation uses an alternating current to generate heat within the tumor, while microwave ablation uses electromagnetic waves to create heat. Both techniques are designed to destroy the tumor while minimizing damage to the surrounding healthy tissue.
RF and microwave ablation are generally performed under sedation or general anaesthesia. They usually required admission for 24 hours and patients can be discharged comfortably the next day.
The success of the procedure depends on several factors, including the size, location, and number of tumors, as well as the patient’s overall health. Possible side effects of RF and microwave ablation include pain, fever, and bleeding, but these are usually mild and short-lived.
Both RF and Microwave ablation technologies are typically indicated for liver tumours less than 5 cm. Microwave ablation is specially indicated for tumours located close to blood vessels for its ability to perform optimum ablation for lesions without the fear of heat sink effect.They can be used as a primary treatment option or in combination with other treatments, such as TACE, surgery or chemotherapy.
Patients should discuss the risks and benefits of RF and microwave ablation with their healthcare provider to determine if it is an appropriate treatment option for their individual case.
