摘要
目的评估CT多平面重建(MPR)技术在肺磨玻璃结节带钩钢丝术前定位中的临床应用价值。方法回顾性分析2014年4月至2015年4月29例行MPR技术引导下肺磨玻璃结节术前穿刺定位患者,评估应用该方法进行肺磨玻璃结节定位的成功率、定位耗时和并发症的发生率。结果 29例肺磨玻璃结节均成功定位(成功率100%),操作平均耗时19.1 min。1例(3.4%)患者出现钩针脱落,6例(20.7%)患者出现无症状气胸,6例(20.7%)患者出现肺内出血,29例患者定位术后均成功切除病灶并获得病理诊断。结论 MPR技术有助于多角度、多平面规划肺磨玻璃结节带钩钢丝定位的穿刺路径,提高肺磨玻璃结节,特别是毗邻纵隔、血管、叶间裂和骨性结构的特殊部位结节的定位的成功率。
Objective To evaluate the clinical application of multiplanar reconstruction （MPR） technique in CT-guided preoperative localization of pulmonary ground-glass nodules with hookwire. Methods A total of 29 patients, who received preoperative localization of pulmonary ground-glass nodules with the help of MPR technique during the period from April 2014 to April 2015, were included in this study. The success rate of localization for pulmonary ground-glass nodules, the time spent in making localization, and the occurrence of complications were evaluated. Results The pulmonary ground-glass nodules were successfully localized in all 29 patients, the success rate of localization was 100%. The mean time spent in making localization was 19.1 min. Intraoperative falling-off of hookwire was observed in one patient （3.4%）, asymptomatic pneumothorax in 6 patients （20.7%） and intrapulmonary hemorrhage in 6 patients （20.7%）. In all patients, the pulmonary lesion was successfully excised and the correct diagnosis was obtained. Conclusion MPR technique can help plan the puncturing path of hoodwire for pulmonary ground-glass nodules as the lesion can be localized from multi-angle and multi-plane views, which can improve the success rate of localization for pulmonary ground-glass nodules, especially when the lesions are located adjacent to the mediastinum, vessels, interlobar fissures or bony structures.
