We systematically reviewed about literatures of stented elephant trunk operation （SET） identified through searches of the electronic databasesEMBASE and Medline, and aimed to summarize studies of patients undergoing SET for extensive aneurysms. Since 1996, Kato Mintroduced a hybrid technique by using stented graft implantation to the descending aorta for treatment of thoracic aortic aneurysm or dissection. It has been describe a good option for extensive thoracic aortic aneurysms and in a fashion similar to the elephant trunk technique.展开更多
