Schematic of the volumes associated with preparation for sac embolization. a Three-dimensional aneurysm volume was measured between positions of non-aneurysmal aorta diameter proximal and distal to the aneurysm (dotted lines, with applicable adjustments for individual anatomy). Perfused aneurysm volume was the aneurysm volume exclusive of preexisting thrombus. b The residual flow lumen volume was calculated by subtraction of the endograft volume (estimated from endograft dimensions in each product’s instructions for use) from the perfused aneurysm volume
