Objectives To evaluate outcomes of unibody bifurcated endovascular stent graft repair.  Methods This is a retrospective, observational, multi-institutional database study of a cohort of consecutive cases, approved by the local Ethics Committee. Records were reviewed of patients diagnosed from 2010 to 2020 with \u201cshaggy\u201d aorta, saccular aneurysm, penetrating aortic ulcer, and isolated aortic dissection located in the infrarenal abdominal aorta. All patients were treated with a unibody bifurcated stent graft. Main outcomes were technical success, procedure complications, long-term patency, and mortality in the follow-up period up to 5 years. Data on demographics, comorbidities, surgical management, and outcomes were analyzed.  Results Twenty-three patients were treated with unibody bifurcated stent graft repair, including 7 cases of \u201cshaggy\u201d aorta, 3 isolated dissections of the abdominal aorta, 4 penetrating aortic ulcers, and 9 saccular aneurysms. Immediate technical success was achieved in 100% of cases. At follow-up, all stent grafts remained patent and there were no limb occlusions. The patients were symptom-free and reported no complications related to the procedure. There were 5 deaths during the follow-up period (median= 4 years), but none were related to the procedure and there were no aorta-related deaths.  Conclusions The present study shows that unibody bifurcated stent grafting is safe and effective in this group of patients with narrow distal abdominal aorta and complex aortic pathology. The results were similar for both infrarenal aortic aneurysms and aorto-iliac atherosclerotic disease.<\/jats:p>","DOI":"10.1590\/1677-5449.200230","type":"journal-article","created":{"date-parts":[[2021,9,22]],"date-time":"2021-09-22T12:12:54Z","timestamp":1632312774000},"source":"Crossref","is-referenced-by-count":4,"title":["Unibody
