目的：探讨肾动脉化疗栓塞术治疗肾癌的作用。材料和方法：47例肾癌用Seldinger法插管行肾动脉造影，再行栓塞化疗。33例栓塞后24小时-7天行手术切除。结果：栓塞前肾动脉造影可显示增生肿瘤血管及肿瘤浸润范围。33例肾动脉栓塞后手术可减少术中出血，易于切除。12例介入姑息治疗者，减轻了临床症状。结论：术前肾动脉栓塞有助于肾癌的手术切除，肾动脉栓塞对不能手术切除老，可作为一种姑息治疗。
Objective: To investigate the effect of renal artery chemoembolization on renal cell carcinoma. Materials and Methods: 47 cases of renal cell carcinoma with Seldinger method of renal artery angiography, and then embolization chemotherapy. Thirty-three patients underwent surgical resection 24 hours-7 days after embolization. Results: Embolization of renal artery angiography can show the scope of tumor and vascular invasion. 33 cases of renal artery embolization surgery can reduce intraoperative bleeding, easy to remove. 12 patients involved in palliative care, reduce the clinical symptoms. Conclusion: Preoperative renal artery embolization is helpful for the surgical resection of renal cell carcinoma. Renal artery embolization can not be surgically removed and can be used as a palliative treatment.
