CT导向下经皮穿刺肺活检对肺内结节性病变的诊断价值

Diagnosis value of CT guided needle biopsy of chest lesion

目的通过对60例CT导向下经皮肺内结节性病灶的活检分析,寻找提高肺内结节性病灶经皮肺活检的一次性穿刺成功率和诊断准确性的方法。方法回顾性分析60例有明确结果的经皮肺活检病例,分析其病灶离胸壁距离远近与肺内结节性病灶经皮肺活检一次性穿刺成率的关系,及诊断准确性、并发症率及其影响因素。结果对肺癌的准确率为89.2%,一次性穿刺成功率81.9%。结论将CT定位技术与穿刺技术有效结合,可望在不增加并发症发生率的前提下,提高一次性穿刺成功率。

Objective To find out an effective method of improving the successful rate of once puncture in CT guided needle biopsy of chest lesion.Methods By looking into 60 cases with definite diagnostic conclusions,the relationship between the distance that the lesion is away from the thoracic cavity wall and the success rate of once puncture in the CT guided biopsy of chest lesion as well as diagnostic accuracy,complication rate and influential factors were analyzed.Results The accuracy rate of diagnosing lung cancer was 89.25% and successful rate of once puncture was 81.9%,which were far higher than the statistics the medical documents put forward.Conclusion Combining CT position techniques and the puncture techniques can improve the successful rate of once puncture without increasing the complications rate.
