Surgeons performing open repair of AAA in the era of endovascular stent grafting are operating on patients who require more complex repairs, including a greater frequency of suprarenal cross clamping, renal vein division, and management of associated iliac aneurysmal and occlusive disease. Despite this, morbidity and mortality rates are similar to those in patients operated on before the initiation of an endovascular stent grafting program.
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.
