Endovascular repair of an innominate artery false aneurysm following blunttrauma

Purpose: To describe a case of endovascular graft exclusion of an innominat e artery pseudoaneurysm arising from blunt trauma. Methods and Results: A 21-year-old patient was admitted following a major r oad accident. Computed tomography (CT) and aortography on admission disclos ed 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 customize d stent-g raft consisting of predilated polytetrafluoroethylene graft: mate rial covering a balloon-expandable Patmaz stent. A CT scan at 1 month and d uplex scans at 6-month intervals documented good stent-graft positioning an d 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 th is minimally invasive alternative to surgery in these clinical situations.
