We aimed to assess the effect of EVAR treatment to the blood flow profile of visceral arteries using 4D-Flow MRI. 10 patients with AAA underwent 4D-Flow pre- and one month post-EVAR. The flow volume at the sections in suprarenal and infrarenal abdominal aorta, the celiac artery, the superior mesenteric artery and the renal arteries were measured. No significant change in blood flow volume was observed within visceral arteries after EVAR despite the placement of stiff stent in the deformed blood pathway.
