目的：探讨内乳动脉在一些胸部病变中的影像学改变及介入治疗价值。材料与方法：对２４例胸部病变患者（肺癌１８例，晚期乳腺癌２例，肺结核合并咯血２例，喉癌肺转移１例，胸锁关节处动脉瘤样骨囊肿１例）行内乳动脉造影后，对内乳动脉有改变者行相应的化疗或栓塞治疗。结果：７例肺癌患者发现除支气管动脉供血外，内乳动脉亦参与供血；２例乳腺癌患者中，１例见内乳动脉及肩胛下动脉有供血，另１例见内乳动脉肋间支及穿支有缺损改变；１例肺结核合并咯血患者可见除支气管动脉扩张扭曲外，内乳动脉亦有此改变；１例胸锁关节处动脉瘤样骨囊肿患者造影可见右内乳动脉近端纵隔支增粗扭曲，并见肿瘤染色。１１例内乳动脉有改变患者分别予以化疗或栓塞治疗，临床症状改善明显。结论：内乳动脉造影在了解一些胸部疾病血供情况及介入治疗方面有重要的临床价值。
Objective: To investigate the imaging changes of internal mammary artery in some thoracic lesions and the value of interventional therapy. MATERIALS AND METHODS: Intra-arterial angiography was performed in 24 patients with thoracic lesions (18 cases of lung cancer, 2 cases of advanced breast cancer, 2 cases of pulmonary tuberculosis complicated with hemoptysis, 1 case of laryngeal lung metastasis and 1 case of aneurysmal bone cyst at the sternoclavicular joint) After the change of the internal mammary artery corresponding chemotherapy or embolization. Results: In 7 patients with lung cancer, the internal mammary artery was also involved in blood supply except for the bronchial artery. In 2 patients with breast cancer, one was found to have blood supply to the internal mammary artery and subscapularis artery and the other to the intercostal branch of the internal mammary artery In addition, 1 case of pulmonary tuberculosis complicated with hemoptysis showed bronchial artery in addition to distortions, the internal mammary artery also had this change; 1 case of sternoclavicular joint aneurysmal bone cyst in patients with angiography can be seen in the proximal right internal mammary artery mediastinal Branch thickening distortion, and see the tumor staining. Eleven patients with changes in the internal mammary artery were treated with chemotherapy or embolization, the clinical symptoms improved significantly. Conclusion: Intra-arterial angiography has important clinical value in understanding the blood supply and interventional treatment of some thoracic diseases.
