选择性肾动脉栓塞治疗肾损伤出血的临床应用

Clinical Application of Selective Renal Artery Embolization for Treatment of Renal Injury Hemorrhage

目的 分析选择性肾动脉栓塞治疗肾损伤出血的疗效和安全性。资料与方法 1992年7月至2005年6月，39例肾脏损伤性出血患者，其中肾脏外伤28例，医源性损伤11例，采用金属弹簧圈行选择性肾动脉栓塞术。结果 DSA证实损伤部位位于肾段或段以下肾动脉分支，全部患者术后1～4d肉眼血尿消失（除2例再次栓塞外），随访4个月～2年，无复发性血尿，无并发症出现。结论 选择性肾动脉栓塞治疗肾损伤出血创伤小、安全、疗效确切，能避免肾脏外科手术。

Objective To evaluate the clinical efficacy and safety of selective renal artery embolization treatment for renal injury hemorrhage. Materials and Methods From July 1992 to June 2005, 39 patients with renal injury hemorrhage, including 28 patients of renal trauma, 11 patients of iatrogenic renal injury, were treated by selective renal artery embolization with steel coils. Results All patients were performed angiographic examinations. The injury sites were segment and their branches of renal artery.After renal artery embolization, macroscopic hematuria was disappeared on the 3rd to 5th day after the procedures, excepting two cases with re-embolization. There was no recurrent hemorrhage and no complications occurred during 2 ～ 24 months follow up.Conclusion Selective renal artery embolization is effective and safe in treating renal injury hemorrhage, with less invasion, less complications and avoiding renal operations.
