a Preprocedure computed tomography angiography (CTA) of a 54-mm diameter, 104-mL infrarenal AAA sac. b Follow-up CTA at 12Â months, illustrating a reduction in aneurysm volume of 48Â mL. The sac was treated with 31 shape memory polymer devices, totaling 38.75Â mL of embolic material, which represented 117% of the calculated residual flow lumen volume outside of the endograft (Lombard Altura) based on preprocedural CTA analysis. Yellow arrows indicate the markers of the shape memory polymer devices
