Aortic Disease and Treatment Approaches

Purpose: To describe a case of endovascular graft exclusion of an innominate artery pseudoaneurysm arising from blunt trauma. Methods and Results: A 21-year-old patient was admitted following a major road accident. Computed tomography (CT) and aortography on admission disclosed an isolated innominate artery pseudoaneurysm. The lesion was stable, so an elective endoluminal repair was undertaken once the patient was treated for his other injuries. The right carotid artery was exposed and controlled, and the aneurysm was excluded by transluminal implantation of a customized stent-graft consisting of predilated polytetrafluoroethylene graft material covering a balloon-expandable Palmaz stent. A CT scan at 1 month and duplex scans at 6-month intervals documented good stent-graft positioning and aneurysm exclusion over a period of 18 months. Conclusions: This case illustrates the potential durability of endoluminal repair of innominate artery lesions and highlights the potential role of this minimally invasive alternative to surgery in these clinical situations.
