RESUMO
Objective: To evaluate the diagnosis value of percutaneous puncture biopsy technique under CT guiding in clinical pathological changes of breast. Methods:46 patients with breast lumps or nodules, including six cases of pleural disease, were carried out percutaneous puncture biopsy under CT guide, where a coaxial Angiotech 17G trocar together with BiopincelSG were used in the puncture process. Results: 44 cases of pathological findings were acquired and the diagnosis ratio was 93.4%, including 9 cases of squamous cell carcinoma, 24 cases of adenocarcinoma, 3 cases of small cell carcinoma, 1 case of metastatic tumor, 1 case of tuberculosis cases, 5 cases of inflammation and 1 case of normal reflexed pleura. 2 cases have no clear diagnosis. Conclusion: The percutaneous lung biopsy technique under CT guide has the merits of less diagnosis trauma, high diagnosis accuracy and high clinical application value.
