The ALD of patients with BTAI is significantly larger when it is measured by IVUS at the time of TEVAR compared with at the time of initial CTA. This difference in ALD may translate to undersizing of endografts used in TEVAR for BTAI. IVUS at the time of TEVAR provides a more accurate measurement of the actual ALD and should be used for endograft sizing for patients with BTAI.
We have previously demonstrated that successful utilization of rEVAR improves the early survival of rAAA patients compared with OSR. This study shows that more patients are able to be discharged to home after rEVAR and that the early survival advantage is continued in midterm follow-up, suggesting that rEVAR should be attempted first when feasible. Further studies are needed to determine the long-term durability of endovascular repair in the management of rAAA as well as the impact on cost and long-term quality of life.
This is the 42nd installment of a series that will highlight one case per publication issue from the bank of cases available online as part of the American Society of Emergency Radiology (ASER) educational resources. Our goal is to generate more interest in and use of our online materials.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
