ABSTRACT
INTRODUCTION:
This study reports our experience with the use of an ethylene vinyl alcohol copolymer (Onyx™) for the treatment of type II endoleak after endovascular repair of abdominal aortic aneurysms (EVAR) in comparison to coils and cyanoacrylate glue.METHODS:
Clinical data of all patients treated for type II endoleak following EVAR between 2009 and 2017 were retrospectively analyzed. Abdominal aortic aneurysm (AAA) diameter and AAA sac volume during follow-up were measured using computed tomography angiography (CTA). Treatment failure variables were created for the change in sac diameter and volume. An increase in sac diameter ≥ 5 mm was considered a failure, as was an increase ≥ 10% in AAA sac volume.RESULTS:
35 patients underwent treatment for a persistent type II endoleak following EVAR. Of these patients, 18 (51.4%) were treated with Onyx and 17 (48.6%) were treated with coils ± cyanoacrylate glue embolization. There were no significant differences between the 2 groups with regard to demographics. The average volume of Onyx used per treatment was 13.4 ml (range 4.5 ml- 39 ml). There was no difference in efficacy between the Onyx and non-Onyx group. Complications were limited to 1 non-target embolization without significant clinical sequelae.CONCLUSIONS:
Ethylene vinyl alcohol copolymer (Onyx™) embolization is similarly effective compared to traditional cyanoacrylate glue or coil embolization in the treatment of type II endoleak after EVAR.Palavras-chave
