RFA
QUESTIONS REGARDING RADIOFREQUENCY TUMOR ABLATION (RFA):
What is Radiofrequency Ablation?
Radiofrequency ablation uses electrical energy through a radiofrequency ablation probe which contains four prongs that are placed directly into the tumor under CT or surgical guidance. The radiofrequency current passed through the probes causes the ions to vibrate at very high speeds, which produces heat, which destroys the cancer tissue.
How many lesions in the liver can be ablated?
Radiofrequency ablation uses electrical energy through a radiofrequency ablation probe which contains four prongs that are placed directly into the tumor under CT or surgical guidance. The radiofrequency current passed through the probes causes the ions to vibrate at very high speeds, which produces heat, which destroys the cancer tissue.
Is there a limit on the size of the lesions that can be ablated?
It is generally recommended that the tumor size be less than 5 centimeters in diameter. Newer probes are currently being developed which will be capable of treating larger tumors. Again, each case is reviewed on an individual basis.
Does Radiofrequency Ablation require surgery?
RFA does not always require surgery. This procedure may be done surgically at laparoscopy, or under CT guidance. The best approach will be recommended to you by Dr. Renner, and is determined by both accessability and safety.
Does RFA require hospitalization?
Radiofrequency ablation is a relatively new technique for treatment of liver tumors and requires observation afterwards for a short period of time. Generally speaking an overnight stay may be required.
Does RFQ cause pain?
No, you are usually heavily sedated or asleep during this procedure, and there should be no discomfort.
