本文回顾性对比分析自1991年10月～1995年5月58例肾癌先后行肾动脉造影、栓塞和手术切除的结果，分析显示：肾癌常见和特异性高的造影征象为肿瘤血管（95％）和肾内血管移位侵蚀中断（90％）以及肿瘤染色（83％）；造影对肾癌分期的总准确率为90％，其中Ⅰ期75％、Ⅱ期92％、Ⅲ期73％；用改进的明胶海绵和自制的白芨粉粒行肾动脉栓塞，可使肾癌手术出血少、易分离，缩短手术时间和提高肾癌切除率。讨论了肾动脉造影和栓塞在肾癌术前诊断和治疗中的作用，以及肾动脉栓塞剂的选用。认为肾癌术前宜常规行肾动脉造影和栓塞。
This article retrospectively analyzed the results of renal arteriography, embolization, and surgical resection of 58 cases of renal cell carcinoma from October 1991 to May 1995. The analysis showed that the common and highly specific imaging features of renal carcinoma are tumor vessels (95%). %) and renal vascular translocation erosion disruption (90%) and tumor staining (83%); the total accuracy of angiography in renal carcinoma staging was 90%, of which stage I 75%, stage II 92%, stage III 73% The renal artery embolization with improved gelatin sponge and homemade alum powder can make kidney cancer less bleeding, easy to separate, shorten the operation time and increase the resection rate of renal cancer. The role of renal arteriography and embolization in the preoperative diagnosis and treatment of renal cancer and the selection of renal arterial embolization agents were discussed. It is considered that renal artery angiography and embolization should be routinely performed before kidney cancer.
