Aggressive Surveillance Is Needed to Detect Endoleaks and Junctional Separation between Device Components after Zenith Fenestrated Aortic Reconstruction [PDF]
, 2019 Background Junctional separation and resulting type IIIa endoleak is a well-known problem after EVAR (endovascular aneurysm repair). This complication results in sac pressurization, enlargement, and eventual rupture.

Propagation-based phase-contrast synchrotron imaging of aortic dissection in mice : from individual elastic lamella to 3D analysis [PDF]
, 2018 In order to show the advantage and potential of propagation-based phase-contrast synchrotron imaging in vascular pathology research, we analyzed aortic medial ruptures in BAPN/AngII-infused mice, a mouse model for aortic dissection. Ascending and thoraco-

ADAMTS4-specific MR probe to assess aortic aneurysms in vivo using synthetic peptide libraries
Nature Communications, 2022 New biomarkers are required to improve the assessment of aortic wall integrity and risk of rupture. Here the authors report the development of an imaging probe for ADAMTS4, which they test in an abdominal aortic aneurysm mouse model and show in vivo ...

A numerical study on the influence of geometry on the rupture risk of abdominal aortic aneurysms [PDF]
arXiv, 2023 Abdominal aortic aneurysms (AAAs) are local dilatations in the abdominal aorta occurring due to weakening of arterial wall. The present work investigates the influence of the ratio of maximum transverse diameter to abdominal height (DHr) on rupture risk of AAA, using hemodynamics and AAA wall mechanics simulations.

Outcomes in the emergency endovascular repair of blunt thoracic aortic injuries [PDF]
, 2013 Thoracic aorta blunt injury (BAI) is a highly lethal lesion. A large number of victims die before obtaining emergency care. Thoracic endovascular aneurysm repair (TEVAR) is a less invasive method compared with open surgery and may change protocols for ...

Novel biaxial tensile test for studying aortic failure phenomena at a microscopic level
BioMedical Engineering OnLine, 2013 Background An aortic aneurysm is a local dilation of the aorta, which tends to expand and often results in a fatal rupture. Although larger aneurysms have a greater risk of rupture, some small aneurysms also rupture. Since the mechanism of aortic rupture

AI-based Aortic Vessel Tree Segmentation for Cardiovascular Diseases Treatment: Status Quo [PDF]
arXiv, 2021 The aortic vessel tree is composed of the aorta and its branching arteries, and plays a key role in supplying the whole body with blood. Aortic diseases, like aneurysms or dissections, can lead to an aortic rupture, whose treatment with open surgery is highly risky.

Numerical simulation of flows in a circular pipe transversely subjected to a localized impulsive body force with applications to blunt traumatic aortic rupture [PDF]
Fluid Dynamics Research, 49(3), 035510 (2017), 2018 Much debate surrounds the mechanisms responsible for the occurrence of blunt traumatic aortic rupture in car accidents, particularly on the role of the inertial body force experienced by the blood due to the abrupt deceleration. The isolated influence of such body forces acting on even simple fluid flows is a fundamental problem in fluid dynamics that ...
