When the ascending aorta and aortic arch must be replaced with a vascular graft, two separate grafts are often required to reconstruct a more anatomically configured aorta. We describe a method of graft tailoring that will result in a more natural shape of the neoaorta, avoiding kinking at the junction of the ascending aorta and the aortic arch.

This study employed large eddy simulation (LES) with the wall-adapting local eddy-viscosity (WALE) model to investigate transitional flow characteristics in an idealized model of a healthy thoracic aorta. The OpenFOAM solver pimpleFoam was used to simulate blood flow as an incompressible Newtonian fluid, with the aortic walls treated as rigid boundaries. Simulations were conducted for 30 cardiac cycles and ensemble averaging was employed to ensure statistically reliable results.

Background: Thoracic Endovascular Aortic Repair (TEVAR) reduced mortality for blunt aortic injury (BAI) from 30-50% to < 10%; however, penetrating traumatic aortic injury (PAI) remains highly lethal (>40% mortality). This study's goal is to determine outcomes of TEVAR for PAI.
Methods: Patients undergoing TEVAR for traumatic aortic injuries were identified from the Vascular Quality Initiative database from 2011-2022.

Objective: Branched prostheses are used to treat aortic arch with dissection. However, changes in the neck vessel geometry and diameter after dissection are not well known. We aimed to evaluate neck vessels geometry and changes in diameter with dissection.

: In the presence of porcelain aorta (PA), transcatheter aortic valve replacement (TAVR) has become a class I therapeutic indication for the treatment of severe aortic valve stenosis. To date, few studies have analyzed the clinical outcomes of TAVR in PA patients. We aim to analyze the calcification patterns of the thoracic aorta in PA patients and to evaluate their clinical implications for TAVR procedures.
