Seal zone also matters for branches

Abstract

Advances in endovascular management of aortic aneurysms have been rapid and paradigm changing during this decade. Successful incorporation of visceral/renal arteries in paravisceral and thoracoabdominal aortic aneurysms using a combination of fenestrations and branches have been the subject of many reports, but questions remain as to the ideal construct for fenestrations/branches and the long-term durability. In the current report, Silverberg et al1 details the incidence of reinterventions required to ameliorate a variety of endoleaks resulting from fenestration and branch instability in patients treated by fenestrated endovascular aortic repair (FEVAR)/branched endovascular aortic repair (BEVAR).
