Deployment of shape memory polymer (SMP) throughout the actual target lumen volume of an abdominal aortic aneurysm (AAA) sac with an ipsilateral approach. A, The flow lumen volume (white) was 128 mL based on preprocedural imaging. B, The estimated target lumen volume was 86 mL (flow lumen volume minus the endograft volume). C, Intraprocedural sacogram showing the actual target lumen volume. D, A flexible 6F sheath was advanced over the jailed guidewire positioned around the circumference of the aneurysm sac blood lumen into the first caudal quadrant (Q1). The other quadrants are also labeled (Q2-Q4). E, After deployment of SMP into the first caudal quadrant, visible via small radiopaque markers. F, Case completion angiogram showing 94 mL of SMP distributed throughout the target lumen volume (based on the fully expanded volume of the devices implanted). The ratio of implanted SMP volume to the preprocedural estimate of the target lumen volume was 1.1, highlighting the role of intraprocedural monitoring in ensuring complete treatment of the actual target lumen volume.
