目的:探讨乳导管造影对导管病变的诊断价值。材料与方法:本文收集乳导管造影21例。其中16例阳性并给手术治疗,5例乳导管造影未发现异常。结果:21例非生理性乳头溢液者,在临床被诊及乳腺钼靶平片上无阳性发现但经乳导管造影后有16例发现乳导管病变。主要征象:(1)导管内可见较小园形透管区;(2)导管影增粗;(23)导管呈杯口状充盈缺损,边缘不光整。结论:对乳导管病变的诊断乳导管造影具有重要作用。 Objective: To evaluate the diagnostic value of ductal catheterization for ductal lesions. Materials and Methods: This collection of 21 cases of ductal angiography. Sixteen of them were positive and were surgically treated. No abnormality was found in 5 cases of catheterization. Results: Twenty - one cases of non - physiological nipple discharge were found no positive findings in clinic and mammography. However, 16 cases of duodenal catheterization were found after transcatheter catheterization. The main signs: (1) smaller circular canal visible within the area; (2) catheter thickening; (23) catheter was cup-shaped filling defects, not the whole edge of the whole. Conclusion: The diagnosis of ductal ductal disease in dairy cow catheterography has an important role.
