Endovascular aneurysm repair: Difference between revisions

'''Endovascular aneurysm repair''' (or '''endovascular aortic repair''') ('''EVAR''') is a type of [[endovascular surgery]] used to treat an [[abdominal aortic aneurysm]] (AAA) or thoracic aortic aneurysm, the procedure then specifically termed '''TEVAR''' (thoracic endovascular aortic/aneurysm repair). In certain occasions, a specially designed custom-made graft device (''"endograft"'', which has holes (fenestrations) on the graft body to maintain the patency of certain important blood vessels, is used for the procedure, which is called '''FEVAR''' (fenestrated endovascular aortic/aneurysm repair). Standard EVAR is appropriate for aneurysms that begin below the [[renal artery | renal arteries]], where there exists an adequate length of normal [[aorta]] (the ''"proximal aortic neck"'') for reliable attachment of the endograft without leakage of blood around the device ("''[[Endovascular_aneurysm_repair#Endoleaks |endoleak]]''").
