Stéphan Haulon (Université Paris Sud, France) tells Vascular News at Aortic Live 2018 in Essen, Germany, about a niche group of patients, i.e., those that have had prior open repair of the ascending aorta following an acute type A dissection, that are likely to do particularly well with branched aortic endograft repair, if they subsequently go on to develop an arch aneurysm. This is because, Haulon says, they often have long tubular grafts in the ascending aorta that function as ideal landing zones.
