Abstract:
Objective To explore the clinical application of individualized coil embolization in the interventional treatment of renal artery aneurysm(RAA).Methods Data of 23 patients with RAA treated by individualized coil embolization were analyzed.There were 27 RAAs,in which narrow-necked RAAs were treated with coil embolization and wide-necked RAAs were treated with stent-assisted coil embolization.The efficacy of the two embolization methods were analyzed and the changes of renal function and symptoms were observed.Results A total of 27 RAAs in 23 patients were successfully embolized at one time,including 23 narrow-necked RAAs in 19 cases treated with coil embolization and 4 wide-necked RAAs in 4 patients treated with stent-assisted coil embolization.The embolization effect of 20 cases(86.96%)reached Raymond grade Ⅰ,and 3 cases(13.04%)reached gradeⅡ.Postoperative computed tomography angiography(CTA)showed that all parent arteries were patent,the RAA was not visualized,and there was no renal infarction.There was no statistical difference in creatinine values before operation,1 month,6 months and 1 year after operation(P>0.05).In the 12 patients with hypertension,there were statistically significant differences in blood pressure at 1 year after operation compared with preoperative,1 month,and 6 months after operation(P<0.05).The symptoms of low back pain and hematuria disappeared after operation.Conclusion Individualized coil embolization for RAA is safe,effective and worthy of clinical promotion.
