胸腔镜切除术前CT引导下记忆合金定位弹簧圈精准定位肺小结节

目的 观察电视胸腔镜手术（VATS）前CT引导下肺结节记忆合金定位弹簧圈对精准定位肺小结节的价值。方法 对92例患者共102个肺小结节（直径≤ 2 cm）于VATS前行CT引导下记忆合金定位弹簧圈定位，定位后24 h内行VATS手术切除结节，观察定位效果及并发症。结果 102个肺小结节定位成功率为98.04%（100/102），定位操作时间8~45 min，平均（17.26±5.92）min；2例2个结节VATS术中发现弹簧圈自肺组织内脱出滞留于胸壁；定位后少量气胸发生率10.78%（11/102），少量肺泡出血发生率12.75%（13/102），均无症状而未予处理。102个结节均经VATS成功切除，无中转开胸病例。结论 VATS术前CT引导下肺结节记忆合金定位弹簧圈可有效定位肺小结节，且安全性较好。

CT-guided accurate localization of small pulmonary nodule with memory alloy coil before thoracoscopic resection

Objective To observe the value of CT-guided accurate localization of small pulmonary nodule with memory alloy coils before video-assisted thoracoscopic surgery (VATS). Methods Totally 92 patients (102 small pulmonary nodules) underwent localization of small pulmonary nodules with memory alloy coils before VATS were enrolled. VATS was performed within 24 h after localization. The localization effect and complications were observed. Results The success rate of localization of 102 small pulmonary nodules was 98.04% (100/102), and the operation time of localization for each lesion ranged 8 min to 45 min,with the average time of (17.26±5.92)min. The memory alloy coils of 2 patients took off from lung tissue and remained in the chest wall in VATS. After localization, the incidence of small amount of pneumothorax was 10.78% (11/102), of small amount alveolar hemorrhage was 12.75% (13/102), whereas the patients had no symptom and untreated. VATS was successfully performed for 102 small pulmonary nodules without conversion to thoracotomy. Conclusion CT-guided accurate localization of small pulmonary nodule with memory alloy coils before VATS is effective and safe.
