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 AND METHODS: 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.
