摘　　要：目的:探讨电磁导航系统在CT引导下肺结块病变的穿刺活检中的应用价值。方法:搜集采用电磁导航辅助CT引导系统进行经皮穿刺肺活检的98例肺结块病变的病例资料,记录扫描次数、辐射剂量、操作时间、穿刺次数等参数,记录穿刺成功例数、穿刺阳性例数和并发症情况。结果:98例患者,96例穿刺成功,成功率97.96%。其中81例患者可以判断良恶性,穿刺阳性率82.65%。平均扫描次数(1.24±0.59)次,平均辐射剂量(401.3±41.2)mGy·cm,平均操作时间(10.63±2.34)min,平均穿刺次数(1.35±0.70)次。15例发生气胸,气胸发生率15.31%,17例发生出血,发生率17.35%;无血胸及空气栓塞发生。结论:电磁导航系统在CT引导下肺结块病变穿刺活检中应用价值大,扫描次数和穿刺次数较少,辐射剂量较低,操作时间较短,能提高穿刺成功率,降低出血并发症的发生率,值得临床应用和推广。Objective：To evaluate the clinical application of electromagnetic navigation system in assisting CT-guided percutaneous needle biopsy of pulmonary lesions.Methods：Electromagnetic navigation system-assisted CT-guided percutaneous needle biopsy was performed in 98 patients with pulmonary lesions.The correlation indexes of puncture operation and the success rate of puncture,and puncture-related postoperative complication in these patients were recorded and retrospectively analyzed.Results：In the group,the mean times of scanning,the mean radiation dose,the mean operation time and the numbers of puncturing were（1.24±0.59）times,（401.3±41.2）mGy·cm,（10.63±2.34）min and（1.35±0.70）times.The puncture success rate was 97.96%.The puncture positive rate was 82.65%.Pneumothorax occurred in 15.31% of all patients.Hemorrhage occurred in17.35%.No other complications such as hemothorax and aeroembolism occurred.Conclusion：For the performance of percutaneous needle biopsy of pulmonary lesions,electromagnetic navigation system in assisting CT-guided can reduce the times of scanning,the numbers of puncturing and occurrence rate of hemorrhage;also shorten the operation time,decrease the radiation dose,and increase the puncture success rate.Therefore,this technique is worth popularizing in clinical practice.
