ABSTRACT
PURPOSE:
To retrospectively evaluate the safety and efficacy of embolization of persistent type II endoleaks occurring after abdominal endovascular aneurysm repair (EVAR) using ethylene vinyl alcohol copolymer (Onyx®). MATERIAL ANDMETHODS:
Between 2008 and 2016, 28 consecutives patients (25 men, 3 women) with a mean age of 75.3years±9 (SD) (range 59-90years) were treated for 29 persistent type II endoleaks with increasing aneurysm size>5mm occurring after EVAR. A total of 35 embolization procedures were performed using Onyx®, via a transarterial route (n=25) or direct puncture (n=10), with or without additional metallic coils. The endpoints were to evaluate the clinical efficacy, corresponding to the stabilization or decrease of aneurism size, and the technical efficacy, corresponding to the ability to complete the embolization.RESULTS:
No severe complications were observed during and after embolization. The primary and secondary clinical efficacies were 75% (21/28) and 96.4% (27/28), respectively. Overall primary technical efficacy rate was 58.6% (17/29), greater for transarterial technique (72.8%) than for direct puncture (14.3%) (P=0.01). Secondary technical efficacy was 72.4% (21/29), with no differences between transarterial (81.8%) and direct puncture (42.8%) (P=0.06).CONCLUSION:
Embolization with Onyx® of type II endoleaks after EVAR appears a safe and effective procedure.Palavras-chave
