目的 :研究介入治疗在骨盆肿瘤术前的临床应用价值。方法 :对 2 1例骨盆肿瘤 (其中 15例恶性 ,6例良性 )做了 30人次的介入治疗 ,所有病例均行 DSA造影 ,并用明胶海绵条做了供养动脉栓塞 ,其中 15例恶性骨肿瘤 (MBT)在灌注化疗的基础上实施动脉内栓塞。于栓塞后 1～ 7d进行手术。结果 :所有病例 DSA造影均表现为相应区域内的肿瘤染色和供应血管增粗 ;并均经手术和 (或 )病理证实 ,肿瘤均有不同程度的坏死、液化和囊变 ,术中易剥离 ,出血少 ,术野清楚 ,缩短手术时间。结论 :术前栓塞能有效减少术中出血 ,提高手术成功率 ,是一种有价值的术前辅助性治疗方法。动脉内化疗优于全身化疗 ,动脉内化疗加栓塞明显优于单纯灌注的疗效 ,介入治疗是骨盆肿瘤治疗的一种行之有效的辅助治疗方法 Objective: To study the clinical value of interventional treatment before pelvic tumor surgery. Methods: Twenty-one cases of 21 pelvic tumors (15 of them were malignant and 6 benign) were involved in the interventional therapy. DSA angiography was performed in all cases, and arterial embolization was performed with gelatin sponge. Fifteen cases of malignant bone tumors MBT) on the basis of perfusion chemotherapy arterial embolization. 1 ~ 7d after embolization surgery. Results: DSA in all cases showed tumor staining and blood vessel thickening in the corresponding region. All of them were confirmed by operation and / or pathology. The tumors all had different degrees of necrosis, liquefaction and cystic change, Less bleeding, clear surgical field, shorten the operation time. Conclusion: Preoperative embolization can effectively reduce intraoperative bleeding, improve the success rate of surgery, is a valuable preoperative adjuvant therapy. Intraarterial chemotherapy is superior to systemic chemotherapy, intra-arterial chemotherapy and embolization was significantly better than the perfusion alone, interventional treatment is an effective adjuvant therapy for pelvic cancer treatment
