CT引导下经皮肺活检48例临床分析

Clinical Analysis of 48 Cases of CT-guided percutaneous pulmonary biopsy

目的 探讨肺部外周性病变的诊断准确性。方法 对痰细胞学阴性纤支镜不能确诊的 48例肺部外周性病变患者 ,在胸部 CT扫描定位下 ,用 2 0 G活检针经皮肺穿刺活检取材 ,行病理学诊断。结果 48例患者共行穿刺 5 3次 ,阳性 (4 3/ 48)占 89.6 % ,阴性 (5 / 48)占 10 .4% ,经手术后病理、临床证实 ,其恶性病变诊断正确率 93.3% (2 8/ 30 ) ,良性病变诊断正确率 83.3% (15 / 18) ,误诊率 10 .4%。术后小量咯血 2例 ,未发生气胸及死亡病例。结论 在 CT引导下经皮肺活检是一种安全、有效的检查手段 。

Objective To explore the accuracy of diagnosis for peripheral pulmonary disease.Methods Guided by chest CT scan,percutaneous pulmonary biopsies were taken with 20G probe for 48 questionable patients with peripheral pulmonary disease who couldn't be accurately diagnosed by fibribronchoscope for lack of positive carcinoma cell in pathology,These patients were then diagaosed pathologically.Results 53 samples of biopsy were from the 48 patients.It showed that 43 out of 48 patients were positive(89.6%) and 5 patients were negative(10.4%).Based on pathological and clinical observation,it was verified that the rates of correct diagnosis for the malign and benign pathological were 93.3%(28/30) and 83.3%(15/18) respectively,and the misdiagnosis rate was 10.4%.No case of pneumothorax or fatality was found.There were 2 patients with small postoperative hemoptysis.Conclusions CT guided percutaneous transpulmonary biopsy is a safe and reliable diagnosis tool that is effective for peripheral pulmonary disease.
