Abstract:
Objective To observe the value of CT guided radiofrequency ablation (RFA) in treatment of lung metastases. Methods Totally 128 lung metastatic lesions in 102 patients were treated with CT-guided RFA. The ablation power range was 40-80 W, the ablation time was 12-25 min, and the effect was evaluated using follow-up CT images. Results All operations were carried out successfully. A total of 120 lesions were completely ablated. CT following-up showed the lesions with no enhancement, with clear edges, the volumes gradually reduced in different degrees, while fiber strips, nodules and hollows could be observed. Nodular enhancement on the margins were observed in 8 lesions in follow-up CT images 3 months later, and RFA was performed again. Complete ablation was achieved in 7 of those 8 lesions, while 1 lesion kept increase, and the patient underwent radioactive particle implantation. After operation, media and massive pneumothorax occurred in 6 patients who underwent thoracic close drainage, while slight pneumothorax and fever were noticed each in 12 patients and released after symptomatic treatment. No serious complication occurred. Conclusion CT-guided percutaneous radiofrequency ablation is safe and effective in treatment of pulmonary metastasis, therefore having high application value.
