Objective To evaluate the diagnostic accuracy of percataneous lung biopsy guided by simulated positioned and CT. Methods 60 patients were treated with percataneous lung puncture biopsy guided by simulated positioned and 60 patients were treated with percataneous lung puncture biopsy guided by simulated CT. All samples were sent to pathological department for cytological evaluation. Results The positive rates guided by simulated positioned and CT were 95%(57/60) and 98. 5%(65/66). The complication guided by simulated positioned and CT were 10% (6/60) and 8. 3% (5/60). There was no significant differences in the two groups(P>0. 05). Conclusion Percutaneous lung biopsy guided by simulated positioned or CT is a simple and safe technique with lower costs, lower complication and higher accuracy.%目的 评价模拟定位机和CT引导下经皮肺穿刺活检对肺部可疑恶性肿瘤的诊断价值并做对比分析.方法 126例肺部可疑恶性肿瘤的患者,60例在模拟机引导下经皮肺穿刺活检；66例在CT引导下经皮肺穿刺活检,所得标本送病理科做细胞学检查.结果 模拟机组活检阳性率95％,CT组活检阳性率98.5％.二组比较无显著性差异(P＞0.05).模拟机组和CT组引起出血和气胸并发症分别为10％和13.6％、8.3％和12.1％.两组比较无显著性差异(P＞0.05).结论 模拟机和CT引导下经皮肺穿刺活检的恶性肿瘤确诊率和并发症相似,均是一种简便、安全、并发症少、费用低、准确率高的检查手段,对肺部病灶特别是周围性病灶具有较高的诊断价值,目前已被广泛接受.
