目的 探讨肾癌根治术前作肾动脉栓塞化疗的价值。方法 对 18例肾癌患者 ,在肾癌根治术前作股动脉穿刺 ,超选择插管至肾动脉行化疗栓塞治疗 ,其栓塞物常规应用明胶海棉以及碘油与化学药物阿霉素的混合乳剂。结果 18例患者栓塞后出现了轻度的反应 ,手术过程中平均出血量明显减少 ,平均出血量 2 5 0ml,肿瘤周围界限清楚 ,易于剥离。结论 肾癌根治术前作肾动脉栓塞化疗治疗是必要的 ,它有利于手术切除 ,减少术中出血 ,其应用的技术关键是超选择的插管
Objective To investigate the value of renal artery embolization chemotherapy before radical nephrectomy. Methods 18 patients with renal cell carcinoma were treated with femoral artery puncture and superselective intubation to the renal artery before and after radical nephrectomy. Chemoembolization was performed with gelatin sponge and lipiodol mixed with doxorubicin Emulsion. Results Eighteen patients had a mild reaction after embolization. The average amount of bleeding during operation was significantly reduced. The average amount of bleeding was 250 ml. The boundary of tumor was clear and easily peeled off. Conclusion Renal artery embolization chemotherapy before radical nephrectomy is necessary, it is conducive to surgical resection, reduce intraoperative bleeding, the application of the key technology is the choice of super-cannula
