Abstract

Endovascular abdominal aortic aneurysm (AAA) repair has been widely used for the treatment of AAA as a safe and efficient method, but endoleaks causing persistent expansion of aneurysm sac may cause aneurysmal rupture and death. Type 3 endoleak is rare but a predominant cause of late rupture. Type 3b endoleak can be misdiagnosed as type 2 endoleak, which is more frequent. Here we report two cases of type 3b endoleak mimicking type 2 endoleak, which were successfully treated by open surgery of partial explantation of the stent-graft and endoaneurysmal interposition graft replacement.
