肾动脉瘤的血管腔内治疗

目的评价血管腔内治疗对于肾动脉瘤（RAA）的安全性及疗效。方法回顾性分析11例接受血管腔内治疗的RAA患者，治疗方法包括单纯以弹簧圈填塞动脉瘤腔（6例）、载瘤动脉栓塞术（3例）和覆膜支架隔绝术（2例），并随访3～68个月。结果11例患者共发现13个RAA（右肾9个，左肾4个），均为真性囊状动脉瘤，对其中11例（11个RAA）行血管腔内治疗。术后5例出现栓塞后综合征，其中4例发生部分肾梗死，肾功能无异常；未见其他严重并发症。随访未见动脉瘤内残腔及内瘘，未见动脉瘤破裂及复发。结论血管腔内治疗RAA安全、有效，成功率高。

Endovascular treatment of renal artery aneurysm

Objective To assess the safety and efficacy of endovascular treatment for renal artery aneurysms(RAA).Methods A total of 11 patients who underwent endovascular treatment were analyzed retrospectively.The endovascular techniques included simple coil filling the sac(n=6),coil occlusion of the parent artery(n=3) and stent-graft implantation(n=2).All patients were followed up from 3 to 68 months.Results Thirteen true saccular RAAs were discovered in 11 patients,9 in the right,4 in the left side.Eleven patients(11 RAA) accepted endovascular treatment.After endovascular treatment,post-embolization syndromes appeared in 5 patients,among them 4 patients were found with partial renal infarct during following-up.There was no else major complication and periprocedural mortality.The rupture or reperfusion of RAA was not observed.Conclusion Endovascular treatment is safe and effective for RAA with high success rate.
