Objective This study aims to evaluate the initial results of a hybrid procedure for treating descending thoracic aortic disease that involves distal aortic arch.It also intends to report our initial experience in performing this procedure.Methods A total of 45 patients(35 males and 10 females) with descending thoracic aortic disease underwent a hybrid procedure,namely,thoracic endovascular aortic repair(TEVAR) combined with supra-arch branch vessel bypass,in our center from April 2009 to August 2014.Right axillary artery to left axillary artery bypass(n =20) or right axillary artery to left common carotid artery and left axillary artery bypass(n =25) were performed.The conditions of all patients were followed up from the 14th month to the 77th month postoperative[mean(38.0 ± 17.1) months].Mortality within 30 days,complications such as endoleak after the hybrid procedure,and stenosis or blockage of the bypass graft during the follow-up period were assessed.Results One case of death and one case of cerebral infarction were reported within 30 days.Two patients underwent open surgery beacuse of endoleak.And a newly formed intimal tear was observed in one patient and the patient underwent a second TEVAR during the follow-up period.Condusion Initial results suggest that the one-stage hybrid procedure is a suitable therapeutic option for thoracic aortic pathologies that involve distal aortic arch.However,this procedure is not recommended for type-B aortic dissection,in which a tear is located in the greater curvature or near the left subclavian artery,because of the high possibility of endoleak occurrence.
