Study on the clinical value of CT-guided percutaneous lung biopsy in the elderly

Objective To discuss the clinical value of CT-guided percutaneous lung biopsy in the elderly.Methods 390 elderly patients with pulmonary masses and nodules were studied,and all of them underwent percutaneous lung biopsy.The correlation between lesion diameter and puncture depth and complications was analyzed;the histological diagnosis of lung biopsy was observed;and the therapeutic effect of complications was observed.Results All 390 patients were successfully punctured,with a success rate of 100.0%,of which 382 patients were successful in one puncture,and the remaining 8 patients were punctured twice,and the puncture was successful in the end.By correlation scatter diagram analysis,the incidence of pneumothorax and hemoptysis was negatively correlated with lesion diameter(r=-0.436,-0.341;P<0.05),and positively correlated with puncture depth(r=0.990,0.968;P<0.05).The histopathological diagnosis showed that there were 262 cases of malignant lesions,accounting for 67.2%,and 128 cases of benign lesions,accounting for 32.8%.Among the 390 patients,55 cases(14.1%)had complications,including 34 cases of pneumothorax(6 cases of delayed massive pneumothorax)and 21 cases of hemoptysis.All patients improved after symptomatic treatment,and no mediastinal emphysema,air embolism,death,etc.occurred.Conclusion CT-guided percutaneous lung biopsy is a small trauma and practical qualitative diagnostic method,and has high clinical application value in the diagnosis of pulmonary mass and nodules in the elderly.
