Abstract：Objective:To explore the influencing factors of bleeding after CT-guided coaxial puncture biopsy of small pulmonary nodules,and to propose corresponding intervention strategies.Method:168 patients who received CT-guided coaxial puncture biopsy of small pulmonary nodules in Binzhou Central Hospital from January 2019 to December 2023 were selected as the study objects,and their basic information,clinical manifestations,imaging features and postoperative bleeding were collected.Patients with postoperative bleeding were selected as the bleeding group(n=14),and those without postoperative bleeding were selected as the no bleeding group(n=154).Univariate and multivariate logistic regression analysis was applied to explore the influencing factors of postoperative bleeding,and corresponding intervention countermeasures were proposed according to the main risk factors.Result:Compared with the non-bleeding group,the lower lobe accounted for a higher proportion of lesions,the lesion size was smaller,the puncture depth was deeper,the number of samples>2 accounted for a higher proportion of patients,and the pathological results showed a higher proportion of tumor patients,with statistical significance(P<0.05).Multivariate logistic regression analysis showed that the lesion location was lower lobe,lesion size,puncture depth and number of samples were>2,and pathological results showed that tumors could be used as high risk factors for postoperative bleeding after CT-guided coaxial puncture biopsy,with statistical significance(P<0.05).Conclusion:The occurrence of postoperative bleeding after CT-guided coaxial puncture biopsy of small pulmonary nodules is related to many factors.Targeted intervention can effectively reduce the occurrence of postoperative bleeding and improve surgical safety.
