骨盆转移瘤血管内介入治疗的探讨

目的：通过１６例骨盆转移瘤３１人次的髂内、外动脉和／或 动脉灌注化疗和栓塞治疗，探讨血管内介入对骨盆的治疗效果。材料与方法：一侧股动脉穿刺插管、髂内、外动不／或股动脉造影，明确骨盆转移存在及其供血一，先行动脉内灌注中，继以真丝微粒和／或明胶海绵碎屑行供血动栓塞。栓后即造观察栓程度。治疗后临床上密切观察症状改变，２－３个月后造影复查，再行动脉内化疗，必要时再行栓塞。结果：本组１６例共行３１人次治疗。

Intra-arterial Treatment of Pelvic Metastases

Objective: To explore intra arterial treatment of pelvic metastases.Materials and Methods:Angiography of internal iliac artery, external iliac artery and/or femoral artery was performed in 16 cases (31 procedures) with pelvic metastases after catheterization via one femoral artery. Once the tumor feeding arteries were identified, arterial themotherapy was carried out and embolization with silk segments and Gelfoam particles was selectively done. Angiography was repeated to determine the degree of embolization. Clinical symptoms were closely observed. Follow up angiography was done two or three months later, and chemotherapy and embolization were repeated when necessary.Results:Sixteen patients underwent 31 treatment procedures. Pain and other symptoms were markedly relieved in all cases. On follow up angiographies, metastatic lesions became smaller, subtler, or even disappeared.Conclusion: Intra arterial chemotherapy with selective embolization is an effective and palliative treatment for pelvic metastases, especially for those patients who are not suitable for much radiation.
