目的:为了减少骨盆脊柱骨肿瘤术中的失血量,提高手术疗效并评价介入治疗在脊柱骨盆肿瘤术中的作用。方法:对13例脊柱骨盆肿瘤患者,通过动脉插管和血管造影,采用不同的化疗药物对肿瘤组织进行局部灌注化疗,并利用明胶海绵、弹簧钢栓对肿瘤血管进行栓塞,择期手术切除肿瘤。结果:所有病人均感疼痛减轻,肿块缩小,术中见肿瘤周围粘(米连)减轻,术中失血明显减少,平均为1250ml,病理检查显示肿瘤有不同程度坏死、液化。结论:骨盆脊柱肿瘤术前介入治疗能够有效地减少术中出血,提高手术疗效,是一种有价值的术前辅助性治疗方法。 OBJECTIVE: To reduce the amount of blood loss during pelvic spine surgery for bone tumors, improve the efficacy of surgery, and evaluate the role of interventional therapy in the treatment of spinal pelvic tumors. Methods: Thirteen patients with spine pelvic tumors were treated with arterial intubation and angiography. Different chemotherapy drugs were used to perform local perfusion chemotherapy on tumor tissues. Gelatin sponge and spring steel plugs were used to embolize tumor blood vessels and tumors were removed surgically. RESULTS: All the patients experienced pain relief and tumor shrinkage. During the operation, the adhesion around the tumor (Mianlian) was relieved. The blood loss during the operation was significantly reduced, with an average of 1250 ml. Pathological examination showed that the tumor had necrosis and liquefaction in varying degrees. Conclusion: Preoperative interventional treatment of pelvic spine tumors can effectively reduce intraoperative bleeding and improve the curative effect. It is a valuable preoperative adjuvant therapy.
