肾动脉化疗栓塞术治疗肾癌的意义

Significance of Renal Artery Chemoembolization in the Treatment of Renal Cell Carcinoma

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 evaluate the effect of renal arery chemoembolization in the treatment of renal cell carcinoma. Material and method: Renal artery angiography and chemoembolization were performed in 47 Patients with renal cell carcinoma. Among them,33 patients could make resection after embolization han 1 to 7 days. Result: Before embolization, the renal artery angiography showed neoplasms hyervessels and area of tumor infiltration. After emboliztion in 33 patients, it could reduce properation bleeding and make resection easily. Clinic symptoms of 12 cases were remited after pafliative chemoemboliation. Conclusion:Preoperatiove embolization of renal artery could make resection easily in the patients with renal cell carcinoma. For nonresectable cases, palliation can be achieved by renal artery embolization.
