title: Embolisation of a proximal type I endoleak post-Nellix aortic aneurysm repair complicated by reflux of Onyx into the Nellix endograft limb.
abstract: We report the first case of intervention for a proximal type 1 endoleak following Nellix endovascular aneurysm sealing repair of an aortic aneurysm. This was complicated by migration of Onyx into one of the Nellix graft limbs causing significant stenosis. Subsequent placement of a covered stent to affix the Onyx between the stent and the wall of the Nellix endograft successfully restored stent patency.
