Use of bare metal stenting is a novel approach for more complete reconstruction of aortic dissection.¹ Treatment advancement with endografting^2,3 and bare stenting for total aortic reconstruction has been previously reported.¹ In this article we report our results for complete endovascular aortic stenting in acute dissection for both type A and B cases.

Deficiencies have persisted with endografts in the treatment of thoracic dissections.⁴ Stent graft closure of the primary entry tear, typically in the proximal descending aorta, results in decompression of the thoracic false lumen with proximal thrombosis and remodeling. However, this technique does not address the need in some cases to more fully remodel the entire aorta and ensure distal branch vessel perfusion.^2,3 Furthermore, the presence of complex distal re-entries, often related to branch vessels, prohibits extensive treatment with standard tube endografts.

Case reports of Z-stent use for prevention of malperfusion suggest its utility in aortic dissection.⁵ Additionally, we have found bare metal stenting accelerates true lumen remodeling, reduces false lumen volume, and enhances branch vessel perfusion. Our study evaluates quantitatively the postdissection true lumen expansion as a result of Z stenting with . . . [Full Text of this Article]
