目的：通过对乳腺癌肿瘤血供的研究，为动脉灌注化疗奠定基础。材料与方法：６例乳腺癌患者，采用Ｓｅｌｄｉｎｇｅｒ技术，行锁骨下动脉造影，然后选择性动脉内灌注ＡＤＭ６０ｍｇ，ＣＤＤＰ８０ｍｇ，ＭＭＣ１２～１８ｍｇ。结果：（１）肿瘤主要血供５０％来自胸廓外侧动脉，肩胛下动脉及胸廓内动脉各占２５％，与以往观点不同；（２）６例乳腺癌经动脉灌注后原发灶及淋巴结均明显缩小。结论：乳腺癌的供血主要是胸廓外侧动脉，其次为肩胛下动脉及胸廓内动脉。作者提出行动脉灌注化疗时，不宜只行胸廓内动脉，而应以上３支动脉一起灌注，才可获得更佳疗效
Objective: To lay a foundation for arterial infusion chemotherapy by studying the blood supply of breast cancer. Materials and Methods: Six patients with breast cancer underwent subclavian artery angiography with Seldinger technique, then selective arterial infusion of ADM 60 mg, CDDP 80 mg, and MMC 12-18 mg. Results: (1) The main blood supply of the tumor was 50% from the lateral thoracic artery, 2% from the inferior scapular artery and internal thoracic artery, which was different from previous views; (2) The primary tumor and lymph node were found in 6 cases of breast cancer after transcatheter arterial infusion. Obviously reduced. Conclusion: The blood supply of breast cancer is mainly the lateral thorax artery, followed by the inferior scapular artery and the internal thoracic artery. The authors propose that when intra-arterial infusion chemotherapy is performed, it is not advisable to only perform internal thoracic arterial vasculature, and that the above three iliac arteries should be perfused together for better efficacy.
