Complications and influencing factors of pneumoconiosis patients undergoing CT guided percutaneous lung biopsy / 中华劳动卫生职业病杂志

ABSTRACT

Objective@#To investigate the safety and influencing factors of ct-guided percutaneous lung biopsy in pneumoconiosis patients.@*Methods@#The data of 63 patients with pneumoconiosis who underwent ct-guided percutaneous lung biopsy in our hospital were studied to analyze the incidence of complications and influencing factors of percutaneous lung biopsy.@*Results@#63 cases of pneumoconiosis patients received CT guided percutaneous lung biopsy. There were 29 cases of complications (46.03%) , including 20 pneumothorax (37.75%) , 12 bleeding (19.05%) , and 3 cases of liquid pneumothorax (4.76%) . The single factor chi square analysis showed that there were significant differences in age, depth of focus, puncture position and puncture times (P<0.05) , and there was significant difference between the occurrence of hemorrhage and age, type of focus, size of focus, and the location of puncture site (P<0.05) . The unconditional LogisticL multiple factor regression analysis showed that the depth of the lesion was an independent risk factor for concurrency pneumothorax, and the size of the lesion was an independent risk factor for bleeding.@*Conclusion@#Complications of CT-guided percutaneous pulmonary biopsy are mainly pneumothorax and hemorrhage. Age, focus type, focus size, focus depth, puncture site, and puncture times are all the factors of complications.
