ABSTRACT
Blunt traumatic thoracic aortic injury (BTAI) is an extremely serious medical condition with a high rate of associated mortality. Recent advances in techniques such as thoracic endovascular repair offer new opportunities to manage the critical BTAI patients in an efficacious yet less invasive manner. A 65 year-old-male suffered from multiple injuries after a fall, including BTAI in the aortic arch, which resulted in dissection of the descending thoracic-abdominal aorta and iliac artery, development of an intimal flap in the left common carotid artery, and dissection of the left subclavian artery. Based on the imaging information of this patient and our clinical experience, the combined treatment of fenestrated thoracic endovascular repair and a chimney technique was immediately planned to fully repair these dissections and moreover prevent further dissection of the branching vessels, additionally to ensure sufficient blood flow in the left subclavian artery and left common carotid artery. The intervention yielded satisfactory early outcomes. Follow-up assessment at six months reported no symptoms or complications associated with the stent-graft. Computed tomography angiography further confirmed adequate stent-graft coverage of the aortic injury.
ABSTRACT
Abstract Regardless the successful treatment of the descending aorta with endovascular prosthesis, for the ascending aorta segment, because of several anatomic and physiologic issues, this technique has been considered an alternative only for high-risk or inoperable patients. Despite restricted indications, hundreds of treatments have been performed worldwide, demonstrating its safety and reproducibility if it is done in high-quality centers. Therefore, understanding patients' selection criteria and technique limitations are critical to its application.

Objective To summarize the clinical experience and significance of 101 cases of thoracic endovascular aortic repair(TEVAR).Methods From October 2008 to August 2013,101 patients received endovascular repair.Among the cases,81 patients were male,and 20 were female.Before operation,all patients underwent thoracoabdominal aortic CTA examination,there were 5 cases of traumatic aortic diseases,10 cases of severe aortic penetrating ulcer,86 cases of Stanford type B aortic dissection.All patients follow up with CTA 1 weeks,3 months,half a year,and annually postoperatively.Postoperative complications,efficacy,morphology and its vascular stent were observed.Results All cases received TEVAR,there were 90 cases of simple repair of aortic lumen (89.11％),11 cases of brachiocephalic vessels bypass (10.89％),2 cases of death (1.98％),1 case of type Ⅰ endoleak(0.99％),3 cases of the application of lumbar cistern drainage(2.97％),1 case of severe stress ulcer(0.99％),1 patient died after surgery with paraplegia,acute renal failure,stroke,lower limb artery embolization,dissection rupture.Conclusion Thoracic endovascular aortic repair has obvious advantage,risks and complications incidence of preoperative period is low,the technology is worth popularizing widely,but needed to pay attention to strictly control the indications of operation and ensure the brain blood supply.
ABSTRACT
OBJECTIVE: This study aimed to assess the surgical morbidity and mortality of thoracic endovascular repair (TEVAR) as compared with open surgical repair (OSR) for isolated descending thoracic aortic disease. MATERIALS AND METHODS: From January 1, 2006 through May 31, 2010, a total of 68 patients with isolated descending thoracic aortic disease were retrospectively reviewed for the presence of perioperative complication, 30-day mortality, and clinical success. The patients were divided into two groups (group 1, OSR, n = 40 vs. group 2, TEVAR, n = 28) and these groups were compared for major variables and late outcomes. RESULTS: The mean age was 58 years (group I = 54 vs. group II = 63 years, p = 0.011). Significant perioperative complications occurred in 12 patients: 8 (20%) in group I and 4 (13%) in group II (p = 0.3). There were five 30 day mortalities of which 4 occurred in group I and 1 in group II (p = 0.23). Clinical success (effective aortic remodeling and complete false lumen obliteration or thrombosis) was achieved in 20 patients (71%). Mean Kaplan-Meier survival rate at 1 year was similar for both groups (group 1 = 87% vs. group 2 = 80%, p = 0.65). CONCLUSION: Thoracic endovascular repair for isolated thoracic aortic disease shows comparable results to OSR. However, the potential for endoleak or rupture remains a challenge that needs to be addressed in the future. Therefore, close follow-up study is needed for the evaluation of satisfactory long-term outcomes.
