This investigation evaluated the results of single-stage thoracic endovascular aneurysm repair (TEVAR) and endovascular aneurysm repair (EVAR) for multilevel aortic disease in a series of nine patients. The lesions repaired included thoracic and abdominal aortic aneurysms (n= 7) and subacute type B dissections with abdominal aortic aneurysms (n=2). All procedures were successfully performed, and none of the patients experienced postoperative stroke or spinal cord ischemia. The median follow-up period for these patients was 18.9 months (range 1.7-31.4 months) and none of the patients exhibited any signs of type I endoleaks or aneurysmal diameter enlargements more than 5 mm. In conclusion, single-stage TEVAR and EVAR procedures for multilevel aortic disease were found to be safe and feasible modalities for high-risk patients.
