CT模拟定位系统引导下经皮肺穿刺活检在诊断老年人肺癌的应用价值

目的探讨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应用价值。方法应用弹簧芯状活检针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78例老年病人进行分析。结果对78例病人的78个病灶共进行95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72例，良性病变6例，总诊断准确率为100％。气胸发生率为6．4％，咯血发生率为12．8％，未发生大出血。结论CT模拟定位系统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。

Clinical value of CTS-guided percutaneous transthoracic biopsy in elder patients with lung cancer

Objective To evaluate the value of CTS-guided percutaneous transthoracic biopsy for the diagnosis of pulmonary lesions in elder patients. Methods The intact data of 78 elder patients underwent percutaneous pulmonary biopsy with a spring-core biopsy needle under CTS guidance were analyzed. The diagnosis of all the cases was confirmed by pathology and follow-up. Results Ninety-five lung biopsies were performed in 78 cases and satisfactory tissue specimens were obtained in all cases, and the success rate was 100%. The diagnosis for malignant tumors and benign lesions was 72 and 6, respectively. The overall accuracy rate was 100%. Pneumothorax was noted in 5 cases（6.4%）and hemoptysis was seen in 10 patients （12.8%） Conclusion CTS-guided percutaneous transthoracic biopsy with a spring-core biopsy needle might be accurate, safe and quick for pulmonary lesions in elder patients.
