Endovascular treatment of thoracic aortic aneurysm: A single-center experience

Background: We assess the effectiveness of thoracic endovascular aortic repair (TEVAR) in patients with thoracic artery aneurysm with a retrospective analysis of our experience and a review of the literature. Methods: Between January 2005 and December 2011, 53 patients with thoracic aortic aneurysm underwent TEVAR. We evaluated the technical success, periprocedural and long-term mortality and morbidity, and follow-up by enhanced computed tomographic scans at 1, 6, and 12 months and annually thereafter. Results: TEVAR was performed in good general conditions in 62.3% of cases and in emergency conditions in 37.7% of cases. A total of 85 endoprostheses were correctly placed, with technical success of 100%. In 18.8% of cases, a carotidesubclavian bypass was performed; 35.8% of cases required drainage of cerebrospinal fluid. Postoperative mortality was 7.5%, and in all cases patients were treated in emergency regimen. The incidence of major postoperative complications was 9.4%, with 2 cases of paraplegia. At a mean follow-up of 25.6 months, 12 cases (22.6%) of endoleak were observed: 5 cases of type IB endoleak were treated with prosthetic extensions; 7 cases of type II endoleak were not treated. There were no thrombotic occlusions, stent migrations, or fractures. Conclusion: TEVAR represents an effective option in the treatment of thoracic aortic aneurysms, with good immediate and long-term results.
