CT导引下经皮肺部肿块穿刺活检术的临床应用研究

目的探讨肺部肿块CT导引下经皮穿刺活检术(percutaneouspuncturebiopsy,PPB)的临床应用价值和影响其诊断正确率的相关因素。方法对72例肺部肿块患者进行CT导引下PPB检查,对比PPB结果与临床影像学诊断以及手术病理结论,并进一步分析影响CT导引下PPB诊断正确率的相关因素。结果肺部肿块CT导引下PPB的穿中率为100%,诊断正确率为89.6%(61/72),并发症发生率为11.1%(8/72)。患者年龄,有无肺气肿,肺部肿块的大小、肿块内部组分为影响肺部肿块CT导引下PPB正确率和引起有关并发症的主要因素。结论CT导引下PPB在肺部肿块的诊断和鉴别诊断中具有安全、准确、简便等优点。为提高PPB的正确率和减少并发症的发生,应注意患者、病灶和操作过程中的相关因素。

Study on Clinical Application of CT -guided Percutaneous Puncture Biopsy of Pulmonary Masses

Objective To explore the clinical application and the relative factors that effect on the diagnostic accuracy in CT-guided percutaneous puncture biopsy(PPB) of pulmonary masses.Methods PPB in 72 cases with pulmonary masses were performed.The results ofsurgery,pathology, image,and the relative factors that effect on the diagnostic accuracy of PPB were analyzed.Results The punctureaccuracy was 100%,the diagnostic accuracy was 89.6%(61/72),the rate of complication was 11.1%(8/72) in CT-guided percutaneous puncture biopsy of pulmonary masses.The determining factors that effect on the diagnostic accuracy and the rate of complication were age of patients,present of emphysema,size and internal content of pulmonary masses in CT-guided percutaneous puncture biopsy.Conclusion CT-guided percutaneous puncture biopsy was a safe,accurate and simple mean of diagnosis and differential diagnosis for pulmonary masses.To improve the accuracy and reduce complication ,the related factors of patients ,lesion,and the technique should be attended.
