Assessment of the Effectiveness of Local Ablathermy Radio Frequency Bronchial Tumors Primitive

Computed tomography (CT) was used to treat tumors under general anesthesia. Thoracic epidural anesthesia was administered in case of contraindication to general anesthesia mostly due to poor respiratory function. All patients were treated with the same multitine electrodes (LeVeen; Boston Scientific, Nattick. MA) measuring 3, 3.5, or 4 cm in diameter and at least 10 mm larger than the diameter of the target tumor. Multiple overlapping ablations were performed, when needed, in different parts of the tumor in order to cover the entire volume.
