Management of innominate artery true aneurysms: A single centre experience

Abstract

Introduction: True aneurysms of the innominate artery are rare and continued controversy exists in literature regarding the best management of these aneurysms. Patients and Methods: The present study reviewed a 5-year experience of managing IA true aneurysms between 2010 and 2015. There were two patients aged 63 and 77 years who were treated successfully by a selective open debranching technique for the exclusion of the aneurysms. The mean follow-up was 2 years. Preoperative information was derived from spiral computed tomography (CT) scanning, magnetic resonance imaging, and color Doppler imaging (CDI). Results: One male and one female were treated successfully. The most common indication for intervention was transient ischemic attack (100%). The 30-day surgical mortality was zero. Graft patency at 6 months as confirmed by CDI was 100%. One patient had graft-related complication at 6 months and subsequently at 24 months which was revised successfully. Conclusion: Exclusion bypass is a satisfactory treatment of these proximal aneurysms and durable. The proximity to the aortic arch makes endovascular treatment challenging and would depend on the dimensions of the arch and ascending aorta. De-branching simplifies the treatment pathway. The natural history of these isolated aneurysms is unknown.
