Treatment of nonaortic aneurysms in the endograft era: aneurysms of the innominate and subclavian arteries

Abstract

Although open aneurysm repair remains the standard of care, the advent of endoluminal techniques and stent grafts has significant potential to improve treatment of aneurysms of the innominate and subclavian arteries. Regardless of the modality chosen, therapy must be individualized and treatments tailored on the basis of anatomic and etiologic considerations. Occasionally, definitive treatment of an aneurysm with endoluminal stent-graft placement is possible for focal aneurysms or pseudoaneurysms of the innominate or subclavian arteries. In other situations, endoluminal grafting may be combined with open repair to allow for the benefits of both techniques. Ultimately long-term follow-up data are necessary to determine whether the durability of the endoluminal approach warrants more widespread use.
