Abstract:
Endovascular aortic aneurysm repair (EVAR) has revolutionized the management of abdominal aortic aneurysms (AAAs), with lower perioperative morbidity and mortality compared to conventional surgical repair. However, late secondary re-interventions after EVAR are still needed before aneurysm rupture in many cases. A patient with impending rupture of an AAA associated with a type I endoleak 7 years after EVAR who was successfully treated with a unique technique of fixation of the proximal aortic neck taking into account the structure of the stent graft is reported. This technique offers a safe solution to late open conversion after failed EVAR.
