摘　　要：目的探讨即时三维重建及类CT图像在胸部肿物经皮射频消融术病灶定位中的作用。方法2009年09月～2010年03月间进行经皮胸部肿物射频消融术13例,15个病灶,均使用即时三维重建图像及类CT图像辅助手术路径的制定,术前、术中分别行旋转DSA采集及三维重建。结果14个病灶一次穿刺成功,15个病灶均被消融针准确穿刺并被电极包围,2例患者出现气胸并发症,9例患者在术后6周复查胸部CT,其中8例病灶缩小或坏死。结论即时三维重建图像及类CT图像在经皮胸部肿块射频消融的手术路径选择、手术质量保证等方面均具有较大的临床价值和意义。Objective To evaluate the value of real-time three-dimensional reconstruction combined with CT-like images in localizing focus in percutaneous radiofrequency ablation of thoracic neoplasms. Methods Thirteen patients with 15 foci were treated with RFA of thoracic neoplasms from September 2009 to March 2010. Puncture path was established by real-time three-dimensional reconstruction combined with CT-like images. Rotational DSA and three-dimensional reconstruction were performed before and during the procedure. Result 14 patients were punctured successfully onetime,and 15 foci were punctured exactly by trocar and surrounded by needles. Pneumothorax occurred in 2 patients. 9 patients underwent chest CT scan within 6 weeks after their procedures. The CT findings showed that 8 foci became contracting or necrotic. Conclusion Real-time three-dimensional reconstruction combined with CT-like images maybe of great clinical value and significance in the choice of procedure path and the assurance of procedure quality in percutaneous radiofrequency ablation of thoracic neoplasms.
