Isolated External Iliac Artery Aneurysms: Recognizing the Rare and Acting Early

Author(s): Patrick D. Conroy

Isolated External Iliac Artery (EIA) aneurysms are exceptionally rare vascular anomalies, often discovered incidentally and lacking clear management guidelines. In this study, we present a case of an asymptomatic 68-year-old man with a true isolated EIA aneurysm successfully treated with endovascular repair using a Viabahn stent graft. We discuss the diagnostic challenges, rationale for early intervention, and procedural considerations unique to this vascular territory. This case highlights the importance of maintaining a high index of suspicion, leveraging incidental imaging findings, and considering endovascular options in anatomically suitable patients. We also emphasize the urgent need for data registries to inform future clinical practice and guideline development.
