腰骶部骨肿瘤的介入性动脉栓塞治疗

Arterial Embolization and Chemoembolization in treatment of Sacrolumbar Bone Tumor

目的探讨选择性腰动脉及髂动脉栓塞及化疗栓塞在腰骶部肿瘤治疗中的价值。方法采用选择性动脉插管,用经高温处理的明胶海绵栓塞或化疗性栓塞供应肿瘤的腰动脉、髂内动脉。结果本组共6例,2例骨巨细胞瘤栓塞后行手术治疗,术中出血量明显减少,平均为1 600 m l,且手术顺利,肿瘤切除彻底;2例血管瘤及2例转移瘤行栓塞及化疗栓塞,肿瘤缩小,症状明显减轻,生活质量提高,延长了生存期。结论在腰骶部骨肿瘤中,选择性腰动脉加髂内动脉栓塞及化疗栓塞是一种安全有效的治疗方法。

Objective To examine the value of selective iliolumbar arterial embolization and chemoembolization in the therapy ot sacrolumbar tumor. Methods Selective arterial catheter was used, and gelatin sponge processed by high temperature or chemoembolization was used to embolize the iliolumbar and internal iliac artery which nourished the tumor. Results In the six case, two ones with osteoclastoma were treated by operation after embolization, whose hemorrhage amount was decreased obviously （ mean = 1600 ml）, and the operation was successful. In two cases with hemangioma and two ones with metastaic tumor, tumors were reduced in size by embolision and chemoembolization and the patients＇symptoms were mitigated clearly, and their life quality was im- proved and survival period was lengthened. Conclusion In the sacrolumbar bone tumor selective iliolumbar and chemoenbolization may serve as a secure and effective therapy.
