Reduction in aneurysm size during the months after an endovascular graft placement generally is considered one of the criteria of success. We report the case of a patient with an abdominal aortic aneurysm rupture occurring 9 months after a bifurcated endovascular graft placement despite a greater than 45% reduction in size noted on contrast-enhanced computed tomography scan performed at 7 months. Biomaterial modifications of the stent and of the Dacron explanted stent-graft are analyzed.
With regard to the instrumentation presently available, this study shows the benefit of a minilaparotomy when performing a laparoscopic aortoaortic or aortofemoral bypass graft for the treatment of aortoiliac occlusive disease and AAA.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
