目的：通过对１２只犬间接淋巴造影的实验研究，探索显示内乳淋巴系统的方法和临床应用的可行性。材料与方法：应用先灵造影剂伊索显，经胸骨双侧缘Ｔ５平面以下分成深肌组、浅肌组和皮内组作多点注射，并在注药后５、１０、１５、２０、２５分钟摄侧位胸片，其中２只犬作造影前后ＣＴ扫描。结果：造影剂注入锁骨中线内侧区域的浅肌层后５～１０分钟，可清晰显示第２、３前肋间的内乳淋巴结及引入淋巴管。ＣＴ扫描可增强诊断效果。结论：注射部位、深度及摄片时间是造影成功与否的关键。本检查方法能在一定时间内较完整地观察到内乳淋巴引流的全程走行，定位显示明确，对于早期发现乳腺癌内乳淋巴转移、制订正确的治疗方案和判断预后具有重要意义，是一项全新的乳腺内乳淋巴系统的检查方法。
Objective: To explore the feasibility and clinical application of indirect lymphadenectomy in 12 dogs. Materials and methods: The application of Schering Pharmacopoeia Aesoprid, divided into deep muscle group, superficial muscle group and intracutaneous group by multi-point injection below the T5 plane of bilateral bilateral sternum, and after 5, 10, 15, 20 , 25 minutes to take lateral chest radiographs, including 2 dogs for CT scan before and after contrast. Results: Contrast medium was injected into the medial clavicular area of the medial superficial muscle 5 to 10 minutes, can clearly show the second and third anterior intercostal lymph nodes and the introduction of lymphatic. CT scan can enhance the diagnostic results. Conclusion: The injection site, depth and time of radiography are the keys to success of radiography. The inspection method can be more complete within a certain period of time to observe the whole run inside the lymphatic drainage, positioning clear, for the early detection of breast cancer, lymph node metastasis, to develop the correct treatment and prognosis of great significance, is a A new method for the examination of intramammary lymphatic system.
