Trans-stent Graft Embolization Using a Brockenbrough Needle for Delayed Rupture Due to Isolated Type II Endoleak after Endovascular Aortic Aneurysm Repair

Abstract

Delayed rupture after endovascular aortic aneurysm repair (EVAR) secondary to an isolated type II endoleak is rare. A woman in her 90s developed an abdominal aortic aneurysm rupture 20 months following EVAR. A type II endoleak was revealed via digital subtraction angiography. The trans-stent graft approach using a Brockenbrough needle was immediately performed, and the endoleak cavity was occluded with n-butyl-2-cyanoacrylate. Trans-stent graft embolization can be adopted promptly following angiography without changing the body position or access site, even in cases of delayed rupture due to isolated type II endoleak.
