Embolization of Persistent Type 2 Endoleaks After Endovascular Treatment of Abdominal Aortic Aneurysms: A Study of Long-Term Success

Endovascular treatment of abdominal aortic aneurysms (endovascular aneurysm repair [EVAR]) has been shown to be effective, with lower perioperative mortality and morbidity than open surgical treatment in patients with compatible anatomy. This benefit is lost after 3 years of follow-up. This could be explained by the higher rate of reintervention in EVAR patients due to endoleaks. Around half of patients with a persistent type 2 endoleak (T2EL) have an increase in aneurysm size. Either endovascular or conventional surgery techniques have been described to treat this type of endoleak. The aim of this study was to measure the long-term success rate of embolization of T2EL in a pragmatic retrospective series.
