目的　探讨应用冲击加缓释法介入治疗妇科恶性肿瘤的疗效。方法　 31例妇科恶性肿瘤患者均进行一次冲击加缓释法介入治疗。在DSA引导下 ,采用Seldinger技术双髂内动脉插管 ,向肿瘤供血动脉灌注化疗药物 (顺铂 -冲击治疗 ;特制丝裂霉素C复合乳剂及 5 FU乳性骨架阻滞剂 -缓释治疗 )并加明胶海绵栓塞子宫动脉。结果　介入治疗症状缓解率达 93.5 4% ,肿块消退率占 90 .32 % ,无明显副反应 ,随访 5个月～ 3年 ,复发 1例 ,死亡 1例 ,2 9例健在 ,其中 2 4例在介入后 15～ 39天内行癌肿根治术。结论　本法作用时间延长 ,副作用小 ,减少反复动脉插管合并症 ,避免长时置管的护理难度 ,为近、远期手术治疗提供操作方便 ,是治疗妇科恶性肿瘤的有效方法 Objective To explore the application of impact and slow release of interventional treatment of gynecological malignancies. Methods Thirty-one patients with gynecologic malignancies underwent an impact and delayed-release interventional therapy. Under the guidance of DSA, the Seldinger technique was used for intratracheal internal iliac arterial infusion to deliver chemotherapy drugs (cisplatin-shock therapy; specially formulated mitomycin C composite emulsion and 5 FU milk-based blockade) ) And add gelatin sponge embolization uterine artery. Results The rate of symptomatic remission was 93.5%. The rate of tumor regression was 90.32%. There was no obvious side effect. The follow-up ranged from 5 months to 3 years. One case was recurred, 1 case died, 29 cases were alive, of which 24 cases After intervention in 15 to 39 days underwent radical tumor surgery. Conclusion This method has the advantages of prolonged action time, less side effects, less complications of repeated arterial intubation, difficulty in long-term catheterization care, convenient operation for proximal and distal surgical treatment, and effective treatment of gynecological malignant tumors
