Objectives: The aim of this study was to evaluate the feasibility, accuracy, and safety of computed tomographic (CT)-guided coil localization before video-assisted thoracoscopic surgery.
Methods: One hundred and eighty-four consecutive patients with 200 pulmonary nodules who underwent CT-guided percutaneous coil localization before thoracoscopic surgery were retrospectively analyzed in this study. Success rate for localization, complication rates, CT findings, and pathological results of the lesions, as well as the data related to surgery were all recorded and analyzed.
Results: All 184 patients with 200 lesions completed localization and resection. The success rate of the coil localization on lesion baseline was 99.0% (198/200) and 98.9% (182/184) on patient baseline. The number of wedge resection, segmental resection, and lobectomy were 179 (89.5%), 19 (9.5%), and 2 (1.0%), respectively. The malignancy rates in a lesion-based analysis were 83.5% (91.1% in ground-glass nodules, 91.4% in part-solid nodules, and 37.9% in solid nodules). No serious complications occurred in all localization procedures.
Conclusion: Preoperative CT-guided percutaneous coil localization is a safe and effective method to facilitate high success rates for both wedge and segmental resection for peripheral pulmonary nodules.

术前CT引导下经皮线圈定位肺结节：单中心184例


目的：本研究的目的是评估计算机断层扫描 (CT) 引导的线圈定位在电视胸腔镜手术前的可行性、准确性和安全性。
方法：回顾性分析184例胸腔镜术​​前CT引导下经皮线圈定位的200个肺结节患者。对定位成功率、并发症发生率、CT表现、病灶病理结果及手术相关数据进行记录和分析。
结果：184例200个病灶全部完成定位切除。病灶基线上线圈定位的成功率为 99.0% (198/200) 和患者基线上的 98.9% (182/184)。楔形切除术、节段性切除术和肺叶切除术的数量分别为 179 例（89.5%）、19 例（9.5%）和 2 例（1.0%）。基于病变的分析中的恶性率为 83.5%（磨玻璃结节为 91.1%，部分实性结节为 91.4%，实性结节为 37.9%）。所有定位程序均未出现严重并发症。
结论：术前CT引导下经皮线圈定位是一种安全有效的方法，可提高外周肺结节楔形切除和节段切除的成功率。
