ABSTRACT
PURPOSE:
The purpose of this study was to determine retrospectively the safety and technical success rate of embolization using ethylene vinyl alcohol copolymer (Onyx®) for persistent type 1A endoleaks after chimney endovascular aneurysm repair (EVAR) for complex aortic aneurysms. MATERIAL ANDMETHODS:
Nine consecutive patients (6 men, 3 women) with a mean age of 78.6 years (range 62-87 years) presenting with persistent type IA endoleaks after chimney EVAR and an increase of aneurysm size were treated using transarterial embolization with Onyx®.RESULTS:
Technical success was obtained in all patients (100%) and no complications were observed. Mean follow-up was 16 months (range 3-35 months). Primary clinical efficacy was obtained for 8/9 patients (89%) and primary technical efficacy for 6/9 patients (67%). Secondary clinical efficacy was 100%, and secondary technical efficacy was 78%.CONCLUSION:
Our results suggest that arterial embolization using Onyx® appears as a feasible and safe endovascular procedure of type IA endoleaks after chimney EVAR, although further validation is now required.Palavras-chave
