The reconstruction of left subclavian artery in thoracic endovascular aortic repair for aortic arch disease

Abstract

Objective This study was designed to evaluate the prognosis of the reconstruction of left subclavian artery(LSA) in thoracic endovascular aortic repair(TEVAR) for patients with aortic arch disease. Methods From January 2010 to August 2016, 55 patients with aortic arch disease(left vertebral artery dominance) who had undergone TEVAR including LSA covered in Fuwai Hospital were enrolled. 28 patients received concomitant reconstruction of LSA. The study endpoints included: postoperative death, reoperation, stroke and aorta-related adverse events. Results Follow-up data were obtained from all patients. The mean follow-up time was(30.0±17.5)months. All patients were diagnosed with left vertebral artery dominance by preoperative computerized tomography of aorta. The preoperative diameter of left vertebral artery was(4.88±0.85)mm while the right vertebral artery was(3.00±0.75)mm. There were no in-hospital deaths, reoperations and aorta-related adverse events. Three patients died and 2 patients experienced Type Ⅳ endoleak during the follow up. Conclusion The mid-term prognosis of the reconstruction of left subclavian artery in thoracic endovascular aortic repair for patients with aortic arch disease are good and long-term follow-up is necessary.
