Determination of Optimal and Safest Proximal Sealing Length During Thoracic Endovascular Aortic Repair.

Objective: To determine the optimal and safest proximal sealing length (PSL) during thoracic endovascular aortic repair (TEVAR), depending on anatomical aortic arch types and proximal landing zones (LZs).

Methods: This was a single centre retrospective observational study of consecutive TEVAR patients (2008-2020). All aortic pathologies requiring Ishimaru landing zone (LZ) 0 - 3 were included; results were stratified by aortic arch type.

Geometrical Analysis and Preliminary Results for the Endovascular Reconstruction of Aortic Bifurcation Using New-Generation Balloon-Expandable Covered Stents in the Kissing Conformation.

Background: The purpose of the study is to perform a postimplantation geometrical analysis and to evaluate early and mid-term outcomes of new-generation balloon-expandable covered stents, used in the kissing conformation to treat obstructive lesions involving the aortic bifurcation.

Methods: A single-center retrospective review of all patients who underwent endovascular reconstruction of the aortoiliac bifurcation for obstructive disease, with the use of Viabahn balloon expandable stents (VBX; W. L.
