Endovascular Aneurysm Repair Using Anaconda Repositionable Aortic Stent Graft Assisted Exclusively by Intravascular Ultrasound Imaging

© R A D C L I F F E C A R D I O L O G Y 2 0 1 9 Access at: www.VERjournal.com Endovascular aneurysm repair (EVAR) has been employed in nearly 70% of aneurysm treatments over the past decade because of its low invasiveness. During EVAR, the precise visualisation of the lowest renal artery (LoRA) and the hypogastric artery (HA) is fundamental for the correct delivery of both the aortic stent graft (ASG) body and Iliac limbs. The visualisation of the LoRA and HA are normally obtained by the injection of a contrast medium (CM), which can cause renal function impairment, acute adverse reactions and requires X-ray exposition. In this study, we evaluated the feasibility of EVAR using only intravascular ultrasound (IVUS) imaging navigation. Since this was a new technique, we decided to employ a repositionable ASG to ensure LoRA patency at the end of the procedure.
