BACKGROUND: The purpose of this study was to evaluate the midterm results of transaortic stent-grafting for distal aortic arch @entity439 or proximal descending aortic @entity439 and the feasibility of this method for thoracic @entity449 repair. METHODS: Twenty-three @entity1 with true distal aortic arch @entity439 or proximal descending thoracic aortic @entity439 were repaired with the stent-graft introduced through the incision on the proximal arch aorta. Follow-up computed tomography was performed every 6 months in 21 surviving @entity1 . The maximum dimension of the excluded aneurysmal space and the maximum aneurysmal diameter were measured and evaluated to determine whether the aneurysmal space decreased or disappeared after this alternative procedure. RESULTS: There was 1 hospital death (4.3%) due to @entity999 . Another @entity1 died of @entity55 1 year after surgery. Twenty-one @entity1 (91%) survived during the follow-up period, but 1 @entity1 (4.3%) suffered from @entity451 . The follow-up period ranged from 12 to 62 months (average, 34.3 +/- 15.2). There were no instances of @entity1756 during the follow-up period. Postoperative serial computed tomography scans showed disappearance or significant shrinkage of the excluded aneurysmal space in 20 of 21 @entity1 (95%), except for the one @entity1 with endoluminal leakage. CONCLUSIONS: Transaortic endovascular stent-grafting was an effective alternative approach to treating distal aortic arch @entity439 or proximal descending aortic @entity439 . The excluded @entity439 disappeared or shrunk after successful placement of the stent-graft.
