RÉSUMÉ
@#Objective To summarize the mid-term follow-up results and postoperative aortic remodeling of treating blunt aortic injuries (BAI) with thoracic endovascular aortic repair (TEVAR). Methods A retrospective study was conducted on BAI patients treated with TEVAR, who were admitted into the Department of Vascular Surgery in Zhongshan Hospital, Affiliated to Fudan University between September 2003 and December 2015. There were 15 males and 9 females at an average age of 45.6±14.0 years. The mechanism of BAI was mainly auto car crash. Totally 25 entry tears were detected and most of them were located at the aortic isthmus. Results Twenty-four BAI patients survived and eventually went through TEVAR. One patient died of pulmonary embolism 1 week post-TEVAR. Rate of technical success, clinical success and perioperative mortality was 100.0%, 95.8%, and 4.2%, respectively. Nineteen patients were followed up with a mean time of 35.1(13-87) months. All of them survived this period. Based on the follow-up imaging of CTA, 18 of them revealed no endoleak or stent migration, and 1 patient of transection still had perfusion of distal false lumen at the abdominal aorta. None of the aortic segments measured in this study showed expansion of ≥5 mm during follow-up. The aorta remodeled well in 94.7% of them. Conclusion TEVAR for treating BAI appears feasible with high rates of technical and clinical success rates. The mid-term follow-up results seems satisfying, but the long-term results are yet to be assessed with further follow-up.
