Abdominal aortic aneurysm is a common vascular disease requiring surgical treatment. Currently, endovascular aortic repair is a good alternative to open surgery. However, high incidence of unfavorable anatomical variants of the proximal landing zone limit the use of endovascular aortic repair in these patients. Additional techniques can increase applicability of endovascular procedure with optimal results. Two patients with unfavorable proximal neck anatomy undergoing endovascular aortic repair with anchor type of proximal fixation devices are reported in the article.
