Acute type A aortic dissection intimal tears by 64-slice computed tomography: a role for endovascular stent-grafting?

Abstract

Location of intimal tear, aortic valve insufficiency, aortic diameter>38 mm are major factors limiting use of ESG for acute type A dissection. Available stents used to treat type B aortic dissection do not address anatomic constraints present in type A aortic dissection in the majority of cases, such that development of new devices would be required.
