Percutaneous ablation means destruction of the tumors in our body by using special needles inserted from the skin. The destructed tissue is reduced in size or eliminated completely over time by natural mechanisms of our body. In this way, the tumor tissue is treated just like a surgical operation.
Percutaneous ablation is a treatment performed with the guidance of radiological imaging methods such as ultrasound, tomography and MRI (magnetic resonance imaging). Thanks to these methods, both the ablation needles and the target tissue (tumor) can be seen simultaneously and the needles are placed in the most accurate manner. For the best possible ablation, the physician performing the procedure should have been trained in the evaluation of imaging modalities (interventional radiologist), should be familiar with ablation methods and with methods of cancer treatment, and be experienced in ablation techniques.
For percutaneous ablation, thermal methods (heating, freezing) are most commonly used. Radiofrequency, microwave and laser destroy the tumor by heating and cryoablation, by freezing. In chemical ablation, some substances such as alcohol are given into the target and tumor cells are destroyed chemically. Irreversible electroporation, also known as Nanoknife, causes death in the tumor tissue by increasing cell wall permeability with a very high electrical current.
