超声造影引导下经皮周围型肺病变穿刺活检诊断准确性的影响因素分析OA

Objective To evaluate the influencing factors on the diagnostic accuracy of percutaneous peripheral lung lesion biopsy guided by contrast-enhanced ultrasound(CEUS).Methods A retrospective analysis was conducted on the clinical data of patients who underwent CEUS-guided percutaneous biopsy for peripheral lung lesions at the Chongqing University Cancer Hospital from January 2020 to March 2024.Patients were divided into a consistent diagnosis group and a inconsistent diagnosis group based on the consistency between the biopsy results and the surgical pathology or clinical follow-up diagnosis.Univariate and multivariate Logistic regression analyses were used to analyze the influencing factors on diagnostic accuracy.Results A total of 343 patients who underwent CEUS-guided percutaneous biopsy were included.294 patients were in the consistent diagnosis group,and 49 patients were in the inconsistent diagnosis group,with a diagnostic accuracy rate of 85.71%.Multivariate Logistic regression analysis showed that lesion size,CEUS enhancement degree,puncture position,and lesion location were independent influencing factors on diagnostic accuracy.Conclusion CEUS-guided percutaneous lung biopsy has high diagnostic accuracy and a low complication rate.Its diagnostic results are influenced by both lesion characteristics and operational factors.
