The following information was reported to gore: in an article titled "short-term outcomes of the t-branch off-the-shelf multibranched stent graft for reintervention after previous infrarenal aortic repair" it states the following: a retrospective two-center study was undertaken.All consecutive patients who underwent endovascular repair using t-branch stent graft after previous infrarenal aortic repair between january 2010 and august 2018 were included.Demographics, past medical history, cardiovascular risk factors, and intraoperative and perioperative details were recorded.Technical success and early (30-day) mortality, morbidity, target vessel patency, and presence of endoleak were analyzed.During the first year of follow-up, survival, freedom from reintervention, and patency rates were recorded.Gore® viabahn® endoprostheses and gore® viabahn® vbx balloon expandable endoprostheses were used as branch grafts in the study as well as non-gore devices.One patient developed target artery instability (type ic endoleak) at the distal branch attachment of the superior mesenteric artery stent that had been bridged using a gore® viabahn® endoprosthesis.This led to a reintervention.(reported separately pt.434-1).Additionally, three target vessels occluded at 12 months post implant: 1 celiac artery (reported separately pt.434-3), 1 superior mesenteric artery (reported separately pt.434-2), 1 right renal artery (this report-pat.434-4).
