肾恶性肿瘤动脉栓塞术

Embolization for renal carcinoma

目的减少肾恶性肿瘤术中出血，提高切除率及对晚期患者的姑息治疗疗效。方法１９８１年２月～１９９６年１０月，对５０例肾恶性肿瘤进行了肾动脉栓塞辅助治疗。本组肿瘤＞７ｃｍ者占９６％。用明胶海绵、钢丝圈及抗癌药施行整体式栓塞。结果栓后行根治术者４６例，平均出血２５４ｍｌ，提高切除率１０％。栓后多有程度不同的疼痛、发热。手术切除间隔期４８小时以内者占８２％。本组无合并症及死亡。结论肾动脉栓塞术是有效而安全的，可选择作为肾恶性肿瘤的辅助治疗。

Objective To decrease bleeding during renal malignancy resection and to get higher resection rate as a paliative treatment for advanced renal carcinoma.Methods 50 cases of renal carcinoma were treated with renal artery embolization from 1981 to 1996. In 96% of the cases the tumour size was larger than 7 cm in diameter. Gelatine,spring coil with antineoplastic agent were used as embolizer.Results After tembolization, the averagebleeding of 46 cases in nephrectomy was 254ml.Resection rate was 10%. Pain and fever varied after embolization in most cases.In 82 6% of the cases, surgery was done within 48 hours after embolization. There was no motality and morbolity in this series.Conclusions Renal artery embolization is an effective and safe procedure. It could be used as an adjuvant therapy for renal carcinoma.
