目的评价CT模拟定位系统(CTS)引导下经皮肺穿刺在诊断老年周围性肺占位病变的临床应用价值。方法2005年1月-2010年1月,应用弹簧芯状活检针在CTS引导下对老年肺部肿块患者行经皮肺穿刺并经病理和临床随访证实,对其中具有完整资料的124例老年病人进行回顾性总结分析。结果对124例病人的124个病灶共进行了141次穿刺活检,全部病例取得了满意的组织学标本,取材成功率为100%。其中恶性肿瘤112例,良性病变12例,总诊断准确率为100%。气胸发生率为5.6%。咯血发生率为12.1%,未发生大出血。结论CTS引导下弹簧芯状活检针经皮肺穿刺活检对老年性肺癌的诊断是一种准确性高,安全可靠又简单易行的诊断方法。
Objective To evaluate the clinical value of percutaneous pulmonary puncture guided by CT simulated positioning system (CTS) in the diagnosis of occupational lesions in the elderly. Methods From January 2005 to January 2010, 124 elderly patients undergoing CPS-guided percutaneous pulmonary lung biopsy under the guidance of CTS were confirmed by pathology and clinical follow-up. Retrospective analysis. Results Totally 141 biopsies were performed on 124 lesions in 124 patients. Satisfactory histological specimens were obtained in all cases, and the successful rate was 100%. One of 112 cases of malignant tumors, benign lesions in 12 cases, the total diagnostic accuracy was 100%. Pneumothorax incidence was 5.6%. The incidence of hemoptysis was 12.1%, with no major bleeding. Conclusion CTS-guided spring core biopsy needle percutaneous lung biopsy for senile lung cancer diagnosis is a high accuracy, safe, reliable and simple diagnostic method.
