“…The usefulness of additional techniques such as transosseous route, artificial pneumothorax, or artificial hydromediastinum for lung RFA [15,16] and hydrodisplacement for renal cryoablation [14] has been reported. Application of such techniques, however, required additional use of CT fluoroscopy.…”

“…Multiple overlapping ablations were performed to ablate the tumor and an adequate margin. If the tumor bordered pleura, an artificial pneumothorax was created for pain relief, using a previously reported technique [15]. If the tumor was near a critical mediastinal structure, an artificial hydromediastinum was created through a needle to separate the lesion from the structure, using a previously reported technique [16].…”

“…The pleural exudate (10-30%) is noticed during the treatment of surface lesions (less than one centimeter under pleura) and is spontaneously resorbed. Less frequent complications include haemoptysis (5-30%), bronchopleural fistula, diaphragm paresis, continuing pains and subcutaneous emphysema 6,7 . Infections (2-5%) are connected with the formation of a cavity after the successful ablation and occur in the case of a lung abscess or aspergillosis in immunocompromised patients 8,9 .…”

Background. Radiofrequency thermal ablation (RFA) is a minimally invasive, image guided technique for destroying tumour cells without damage to adjacent healthy tissue. It is used for partial or complete ablation of non resectable lung cancers and cancers of metastases to lung, providing an effective, relatively safe option for patients ineligible for surgery. We describe our experience with it. Methods. In 2005 and 2006, we performed radiofrequency ablation of 7 lung lesions in 6 patients. RFA was done percutaneously under image guided CT scan in 5 patients and in one patient during thoracotomy when we found a radically unresectable tumor necessitating debulking. CT lung screening was performed after 6 months and PET/CT was done within 12 months. Results. In the course of the screening, we diagnosed regression in 2 patients, a stationary state in 2 cases and local tumor progression in 2 patients, using computed tomography within 6 months after RFA. Using PET/CT within 12 months, we diagnosed non-ablation and liver metastases (there were none before) in one of the two patients with a stationary state diagnosed by means of CT before and recurrence of primary tumor in another patient. In one case of diagnosed regression, we diagnosed tumor progression. The patients survived an average of 30 months (range 9 to 60 months). Conclusion. RFA of lung tumors is an easy method with little patient discomfort. It can be performed percutaneously using guided CT under general anaesthesia. RFA of lung tumors possibly alone or in combination with oncology treatment can prolong patient life.

“…The parietal pleura is anesthetized and systemic analgesics are administered, as thermal ablation of parietal lesions or close to the pleura can be painful during or after the procedure. When treating a lung tumor close to the pleura, an artificial pneumothorax can be obtained to reduce the pain (36) (Fig. 7).…”

Lung cancer is the leading cause of death related to cancer. Fifteen to thirty percent of patients with a localized lung cancer are actually inoperable as they present with poor general condition, limited cardiopulmonary function, or a too high surgical risk. Therefore, minimally invasive treatments are needed and percutaneous ablation seems an attractive option. Thermal ablation can be performed by delivering heat (radiofrequency, microwave, laser) or cold (cryotherapy) through a needle inserted into the tumor under CT guidance. The ideal lesion is less than 2 or 3 cm in diameter. Success of percutaneous thermal ablation appears to be close to those of surgery for localized lung cancer. Nevertheless studies are still needed to definitely assess the role of ablation compared to other emerging techniques, as stereo tactic radiotherapy as well as potential synergy with other treatments.
