Abstract
OBJECTIVES
Videothoracoscopic visualization and/or palpation of pulmonary nodules may be difficult due to their location, small size or limited solid component. The purpose of this study is to present our experience with computed tomography (CT)-guided preoperative localization of pulmonary nodules by percutaneous marking with radio-labelled iodine-125 seeds.
METHODS
A total of 34 pulmonary nodules were marked under CT with the placement of 33 radio-labelled iodine-125 seeds in 32 consecutive patients.
RESULTS
All patients underwent biportal video-assisted thoracic surgery (VATS) and in no case was conversion to thoracotomy necessary. A total of 88.2% of the lung nodules were successfully resected. In the remaining 11.8%, migration of the seed to the pleural cavity occurred, although these nodules were still resected during VATS. Of all the patients with pneumothorax after the marking procedure, only one required chest tube placement (3.1%). No major postoperative complications were observed.
CONCLUSIONS
Preoperative marking of pulmonary nodules with I-125 seeds under CT guidance is a feasible and safe technique that allows their intraoperative identification and resection.

使用 I-125 种子对肺结节进行术前无线电引导定位:单一机构 32 名患者的经验

摘要
目标
由于肺结节的位置、体积小或实性成分有限,胸腔镜可视化和/或触诊可能很困难。本研究的目的是介绍我们在计算机断层扫描 (CT) 引导下通过放射性碘 125 种子经皮标记术前定位肺结节的经验。
方法
在 CT 下共标记了 34 个肺结节,并在 32 名连续患者中放置了 33 个放射性标记的碘 125 种子。
结果
所有患者均接受了双通道电视胸腔镜手术 (VATS),并且在任何情况下都不需要中转开胸手术。共成功切除88.2%的肺结节。在剩余的 11.8% 中,发生了种子向胸膜腔的迁移,尽管这些结节在 VATS 期间仍被切除。在标记手术后的所有气胸患者中,只有一名需要放置胸管(3.1%)。未观察到严重的术后并发症。
结论
在 CT 引导下用 I-125 粒子对肺结节进行术前标记是一种可行且安全的技术,可以在术中对其进行识别和切除。
