The clinical application of DSA and Xper-CT in guiding lung tumor radiofrequency ablation procedure

Objective To discuss the clinical application of DSA and Xper-CT in guiding lung tumor radiofrequency ablation(RFA). Methods Navigated by DSA and Xper-CT images, RFA was performed in21 patients with lung tumor. The tumors included peripheral lung cancer(n = 3) and lung metastases from hepatocellular carcinoma(n = 12) or from colorectal cancer(n = 6). The lesions were located at left upper lobe(n = 5), at left lower lobe(n = 2), at right upper lobe(n = 5), at right middle lobe(n = 6) and at right lower lobe(n = 4). One lesion was situated at the right thoracic wall and one lesion was situated at the left thoracic wall. Results A total of 24 lesions were detected in the 21 patients. Of the 24 lesions,successful puncturing with single procedure was obtained in 22, with a success rate of 91.67%. Two lesions had the diameter less than one cm, and the treatment was accomplished after two times of puncturing.Conclusion For the treatment of lung tumors, DSA and Xper-CT-guided radiofrequency ablation is clinically-safe and technically-simple with higher localizing accuracy. Therefore, this technique should be recommended in clinical practice.
