The next generation of fenestrated endografts: results of a clinical trial to support an expanded indication for aortic arch aneurysm treatment

The authors review their shot- and mid-term experience with a new precurved fenestrated aortic endograft in the treatment of aortic arch aneurysms.  This multicenter study included 393 patients (2010-2011). 94% of patients had landing zone <20 mm and in 62% the landing zone was less than 15 mm.  The authors report technical success of 99.2%. The procedures were complicated by endoleak in 17 patients, stroke in 7, and six deaths. Type I endoleak was related to the maximum length of the aneurysm and in cases with proximal lending zone <15 mm.
