Abstract:
Objective To evaluate the clinical application of sequence puncturing and double-needle pulling-inserting technique in CT-guided biopsy of small pulmonary nodules.Methods A total of 57 admitted patients with solitary pulmonary nodule from March 2020 to February 2023 were enrolled in this study.With the help of sequence puncturing and double-needle pulling-inserting technique CT-guided puncture biopsy of the pulmonary nodule was carried out for all patients.The pulling-back rate,off-target rate,target periphery rate and target center rate of the coaxial needle,the length of biopsy tissue strip,the success rate of lung nodule biopsy,and complications were recorded.Results Among the 57 patients,pulling-back of needle was seen in 2 patients(3.5％).The needle-tip was located at the center of pulmonary nodule in 52 patients(91.2％)and at the periphery of pulmonary nodule in 5 patients(8.8％),and no off-target of needle-tip occurred.The length of biopsy tissue strip in the cut groove was equal to the diameter of the target nodule in 42 patients(73.7％),≥radius of the target nodule in 11 patients(19.3％),＜radius of the target nodule in 4 patients(7.0％),and no absence of biopsy tissue strip was seen.The success rate of pulmonary nodule biopsy was 100％.The complications included pneumothorax(n=12,21.1％),needle tract bleeding(n=10,17.5％),and biopsy area bleeding(n=14,24.6％).Conclusion Due to the influence of internal stress,the currently adopted synchronous puncture mode and biopsy pattern are not an ideal method.The tail hanging-thread method of coaxial needle can eliminate the influence of internal stress,the sequential puncturing mode can improve the puncture accuracy of pulmonary nodules,and the double-needle pulling-inserting technique can improve the success rate of biopsy,while the incidence of complication is within the acceptable range.(J Intervent Radiol,2024,33:528-532)
