Backgroud: endovascular implantation of the aortic stent-graft is a method of choice in treatment of aneurysms of the infrarenal abdominal aorta, especially in patients with high surgical risk.This strategy is characterized as less in-hospital complications, shorter in-hospital stay All these circumstances show some advantages of endovascular treatment compared with traditional «open» surgery. Besides that, there are some limitations for aortic endoprosthesis implantation, including short or conical proximal neck, severe angulation of aneurysmatic neck and tortuosity of arteries, insufficient diameter of iliac-femoral segment arteries for stent-graft delivery

Materials and methods: we report two clinical cases of successsful implantation of novel stent-graft OVATION PRIME in patients with adverse anatomy, precisely small diameter of crossing profile and original technology of proximal fixation of endoprosthesis.

Results: the use of innovative models of stent-grafts allows to proceed aortic endoprosthesis implantation with minimal risk of complications in certain patients with adverse vascular anatomy, who were previously deemed unsuitable for endovascular treatment.
