Hybrid Surgical and Endovascular Management of Ascending and Arch Dissection.

Tech Vasc Interv Radiol 2021 Jun 26;24(2):100755. Epub 2021 Jul 26.

Department of Cardiac Surgery, University of Michigan, Ann Arbor, MI.

Historically, a variety of non-dissection proximal aortic pathologies with suitable anatomy have been treated with thoracic endovascular aortic repair (TEVAR) with high technical success rates. However, TEVAR use for acute type A aortic dissection has been extremely limited due to the unique challenging anatomic and clinical features and the lack of specifically-designed endoprostheses. These features include: proximity of the aortic valve, coronary arteries, and supra-aortic vessels, related aortic insufficiency, diffusely dilated aorta diameter, entry tear extension into the aortic root and/or aortic arch, the dissection involvement of supra-aortic vessels, high degrees of ascending aortic curvature and notable length discrepancies between the greater and lesser curvatures, and tissue fragility at prosthesis-tissue transition zones.
