BACKGROUND: This study aimed to present our experience in patients with acute traumatic thoracic aortic transection treated by endovascular stent-graft.

METHODS: From October 2011 to October 2014, eleven patients were brought to our hospitals after suffering motor vehicle accident or fall from height. Computed tomography revealed acute traumatic transection of the thoracic aorta at the aortic isthmus just distal to the left subclavian artery in nine patients, at the middle or distal thoracic aorta in two, and both aortic isthmus and middle thoracic aorta in one. Endovascular technique was preferred as the treatment modality. All patients, except one, were treated within twelve hours of diagnosis.

RESULTS: Deployment of stent-grafts was successful in all cases. The stent-grafts were oversized between 10% and 20%. The origin of left subclavian artery was covered with stent-graft in six patients to achieve adequate proximal landing zone. In two of them, carotico-subclavian bypass and periscope graft placement were applied to maintain subclavian artery blood flow. There were no procedure related deaths, paraplegia or ischemic complications. A patient with cardiac arrest, on whom cardiopulmonary resuscitation and transient aortic balloon occlusion within the aorta were applied in the angiography suit died at the postoperative twelve hours. Mean hospital stay after procedures was 14.8 days (range, 4-60 days). Mean follow-up time of ten patients was 16.6 months (range, 1-36 months).

CONCLUSION: Our study supports that thoracic endovascular aortic stenting for acute transection is promising in terms of short- and mid-term results similar to other studies in the literature.
