摘要
目的探讨经皮肾动脉造影及栓塞治疗肾动脉假性动脉瘤的临床价值。方法 2012年1月-2014年2月15例泌尿系结石术后尿道出血,经皮肾动脉造影诊断为肾动脉假性动脉瘤,导管超选择进入载瘤动脉近端,使用弹簧圈和明胶海绵栓塞载瘤动脉。结果 15例经肾动脉造影均能清晰显示假性动脉瘤,其中位于叶间动脉11例,弓状动脉3例和小叶间动脉1例,经导管弹簧圈栓塞后尿道出血停止。1例介入栓塞术后2 d再次出现尿道出血,再次栓塞后出血停止。栓塞术后2例出现一过性肾绞痛;7例体温37.8-39.3℃,持续3-8 d。15例随访3-24个月（平均15个月）,无肾功能不全和尿道出血发生。结论经皮肾动脉造影和经导管栓塞治疗肾动脉假性动脉瘤安全、有效。
Objective To evaluate the clinical value of percutaneous renal artery angiography and embolization of the renal artery pseudoaneurysms. Methods A retrospective analysis was made on 15 cases of postoperative urethral bleeding following urinary calculi surgery from January 2012 to February 2014,which were diagnosed of renal artery pseudoaneurysms via the renal artery angiography. Superselective catheter placement was carried out into the proximal of parent artery and the pseudoaneurysm was embolized by using a coil and gelatin sponge. Results Renal artery angiography clearly displayed pseudoaneurysms in the 15 cases,which were located in interlobular artery in 11 cases,arcuate artery in 3 cases,and minor interlobular artery in 1 case. Urethral bleeding was stopped after using gelatin sponge and spring coil embolization. Among them urethral bleeding recurred in 1 case after two days,and a second embolization was conducted. After the embolization,transient renal colic happened in 2 cases and a fever of37. 8-39. 3 ℃ lasting for 3-8 d was seen in 7 cases. Follow-ups for 3-24 months（ mean,15 months） showed no renal dysfunction and urinary tract bleeding. Conclusion The transcatheter embolization and angiography can diagnose and treat renal artery pseudoaneurysms,with safe and effective outcomes.
