目的：评价无水乙醇肾动脉栓塞术减少肾癌切除术中输血量的效果。方法：1980~1990年连续93例肾细胞癌患者中，24例在术后24小时内行肾动脉栓塞术。结果：栓塞组肿瘤体积大于非栓塞组(平均体积分别为595mL和257mL)(P<；0.05)。接受完全栓塞术的大血管多血管肿瘤患者的平均输血量明显少于对照组患者(250比800毫升；P=0.01)。结论：完全酒精栓塞可显著减少大血管多血管肾细胞癌切除术中的输血量，且不完全栓塞可增加输血量。术前栓塞术必须完整，并应更广泛地进行。
PURPOSE: The authors evaluated the effectiveness of preoperative ethanol renal artery embolization in reducing transfusion requirements during nephrectomy for renal cell carcinoma.PATIENTS AND METHODS: Of 93 consecutive patients who underwent nephrectomy for renal cell carcinoma from 1980 to 1990, 24 patients underwent embolization within 24 hours of nephrectomy. Finding in this group were compared with those in 69 control patients who underwent surgery without preoperative embolization.RESULTS: Embolized tumors were larger than nonembolized ones (mean volume, 595 vs 257 mL) (P < .05). Patients with large hypervascular tumors (volume over 250 mL) who underwent complete embolization received significantly smaller mean blood transfusion volumes than control patients (250 vs 800 mL; P = .01). The transfusion volume associated with incomplete embolization was higher than that associated with no embolization.CONCLUSION: Complete alcohol embolization significantly reduces the volume of blood transfused during nephrectomy for large hypervascular renal cell carcinomas, and incomplete embolization is associated with larger transfusions. Preoperative embolization must be complete and should be performed more widely.
