Abstract

PURPOSE

We aimed to evaluate the diagnostic accuracy and safety of computed tomography (CT)-guided biopsy of pulmonary lesions with fine needle aspiration (FNA) using non-coaxial technique.

METHODS

We analyzed 442 patients who underwent CT-guided lung biopsy with FNA and non-coaxial technique to determine the diagnostic outcomes, complication rates, and independent risk factors for diagnostic failure and pneumothorax.

RESULTS

Diagnostic accuracy, sensitivity, and specificity were 97.6%, 97.3%, and 100%, respectively. Age and >35 mm lesion size were significant risk factors for diagnostic failure. The rates of pneumothorax and chest tube placement were 19% and 2.9%, respectively. Middle and lower lobe location, lesion to pleura distance >7.5 mm, and >45° needle trajectory angle were significant risk factors for pneumothorax.

CONCLUSION

CT-guided FNA of pulmonary lesions with non-coaxial technique is a safe and reliable method with a relatively low pneumothorax rate and an acceptably high diagnostic accuracy.

摘要

目的

我们旨在评估使用非同轴技术的计算机断层扫描(CT)引导下经细针穿刺抽吸(FNA)对肺部病变进行活检的诊断准确性和安全性。

方法

我们分析了442例行CT引导下经FNA非同轴技术肺活检的患者,以确定诊断结果、并发症发生率以及诊断失败和气胸的独立危险因素。

结果

诊断准确性、敏感性和特异性分别为97.6%、97.3%和100%。年龄和病变大小>35 mm是诊断失败的显著危险因素。气胸率和置胸管率分别为19%和2.9%。中叶和下叶位置、病变与胸膜距离>7.5 mm以及针道角度>45°是气胸显著危险因素。

结论

CT引导下经非同轴技术对肺部病变进行FNA是一种安全可靠的方法,气胸率相对较低,诊断准确性较高,可接受。
