肺功能检查评估CT引导下经皮肺活检术后发生气胸的临床价值

Clinical Value of Pulmonary Function Examination in Evaluating the Pneumothorax after the CT-guided Percutaneous Lung Biopsy

目的探讨和分析肺功能检查对CT引导下经皮肺活检术后发生气胸的临床价值。方法随机选取2013年1月—2017年1月期间在该院行CT引导下经皮肺活检手术的50例肺外周孤立性病变患者,将其作为实验组,另外选取同时期来该院就诊的50例肺外周病变做穿刺后未发生气胸的患者作为对照组,所有患者均进行肺功能检查评估,观察患者的相关指标:第1秒用力呼气容积(FEV1)占预计值百分比、用力肺活量(FVC)占预计值百分比、FEV1/FVC、穿刺针经过肺组织的深度、患者的年龄以及病灶的直径。结果经检查,实验组患者发生气胸的人数为14例(28%),第1秒用力呼气容积(FEV1)占预计值百分比(63.67±8.41)、用力肺活量(FVC)占预计值百分比(85.63±7.59)、FEV1/FVC(53.24±8.57)均较对照组(89.62±13.24)、(93.64±8.07)、(86.91±11.26)低,两组差异有统计学意义(P<0.05)。并且,患者的年龄、病灶直径以及穿刺针经过肺组织的深度与气胸密切相关,气胸患者的年龄更大,穿刺针经过肺组织的深度更深,病灶直径更大。结论肺功能检查对于CT引导下经皮肺活检术后发生气胸的评估具有非常明显的临床价值,第一秒用力呼气容积占预计值百分比以及FEV1/FVC显著降低者,术后非常容易发生气胸现象,因此,临床上对这类患者应该引起重视,降低气胸风险,维护患者的生命健康安全。

Objective To explore and analyze the clinical value of pulmonary function examination in the treatment of pneumothorax after percutaneous lung biopsy under the guidance of CT. Methods 50 cases of patients with solitary pulmonary peripheral lesions undergoing CT-guided percutaneous lung biopsy surgery in our hospital from January 2013 to January 2017 were selected randomly as eh experimental group, and 50 cases of patients without pneumothorax after puncture in our hospital at the same period were selected as the control group, and the lung function of all patients was examined and evaluated, and the FEV1, FVC, FEV1/FVC, depth of the puncture needle through the lung tissue, age and diameter of lesions were observed. Results After examination, there were 14 cases（28%） with pneumothorax in the experimental group, and the FEV1, FVC, FEV1/FVC, were lower than those in the control group [（63.67±8.41）,（85.63±7.59）,（53.24±8.57）vs（89.62±13.24）,（93.64±8.07）,（86.91±11.26）], and the differences were statistically significant P〈0.05, and the age, diameter of lesions and depth of the puncture needle through the lung tissue were closely related to the pneumothorax, and the older the patients, the deeper the depth of the puncture needle through the lung tissue, and the bigger the diameter of lesions. Conclusion The clinical value of pulmonary function examination in the treatment of pneumothorax after percutaneous lung biopsy under the guidance of CT is very obvious, and the patients whose FEV1, FVC, FEV1/FVC obviously decrease, are easy to suffer from pneumothorax, therefore, we should attach importance to those patients, thus reducing the pneumothorax risks and maintaining the life security of patients.
