Comparison of existing aneurysm models and their path forward [PDF]
, 2020 The two most important aneurysm types are cerebral aneurysms (CA) and abdominal aortic aneurysms (AAA), accounting together for over 80\% of all fatal aneurysm incidences. To minimise aneurysm related deaths, clinicians require various tools to accurately estimate its rupture risk. For both aneurysm types, the current state-of-the-art tools to evaluate

Mechanisms of oxidative stress in human aortic aneurysms — association with clinical risk factors for atherosclerosis and disease severity [PDF]
, 2013 Aortic abdominal aneurysms (AAA) are important causes of cardiovascular morbidity and mortality. Oxidative stress may link multiple mechanisms of AAA including vascular inflammation and increased metalloproteinase activity.

Infective abdominal aortic aneurysm [PDF]
Heart, 2001 An 81 year old woman with hypertension and diabetes mellitus was admitted for evaluation of severe lumbago and a month long history of high fever of unknown origin. Laboratory investigations showed white blood cell count of 0.234 × 1012/l and a C-reactive protein concentration of …

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.

Generation of Patient-specific Structured Hexahedral Mesh of Aortic Aneurysm Wall [PDF]
arXiv, 2022 Abdominal Aortic Aneurysm (AAA) is an enlargement in the lower part of the main artery Aorta by 1.5 times its normal diameter. AAA can cause death if rupture occurs. Elective surgeries are recommended to prevent rupture based on geometrical measurements of AAA diameter and diameter growth rate.

Mechanosignals in abdominal aortic aneurysms
Frontiers in Cardiovascular Medicine, 2023 Cumulative evidence has shown that mechanical and frictional forces exert distinct effects in the multi-cellular aortic layers and play a significant role in the development of abdominal aortic aneurysms (AAA). These mechanical cues collectively trigger signaling cascades relying on mechanosensory cellular hubs that regulate vascular remodeling ...

Detection and Visualization of Endoleaks in CT Data for Monitoring of Thoracic and Abdominal Aortic Aneurysm Stents [PDF]
, 2016 In this paper we present an efficient algorithm for the segmentation of the inner and outer boundary of thoratic and abdominal aortic aneurysms (TAA & AAA) in computed tomography angiography (CTA) acquisitions. The aneurysm segmentation includes two steps: first, the inner boundary is segmented based on a grey level model with two thresholds; then, an ...

Micromanaging Abdominal Aortic Aneurysms [PDF]
International Journal of Molecular Sciences, 2013 The contribution of abdominal aortic aneurysm (AAA) disease to human morbidity and mortality has increased in the aging, industrialized world. In response, extraordinary efforts have been launched to determine the molecular and pathophysiological characteristics of the diseased aorta.

Targeting interleukin-1β protects from aortic aneurysms induced by disrupted transforming growth factor β signaling [PDF]
, 2017 Aortic aneurysms are life-threatening conditions with effective treatments mainly limited to emergency surgery or trans-arterial endovascular stent grafts, thus calling for the identification of specific molecular targets.
