From aneurysm to aneurysmal vasculopathies [PDF]

Operative Techniques in Neurosurgery, 1999
Today, aneurysms raise a number of challenges. Medical challenge: The emergency and severity of the pathology have led to passionate debates that unfortunately stall progress in our knowledge of the underlying disease (or diseases). Indeed we can suppose that some measure of bleeding, perhaps even early recurring hemorrhage, has gone undiscovered and ...

Semiautomated 3D mapping of aneurysmal wall enhancement with 7T-MRI

Scientific Reports, 2021
Aneurysm wall enhancement (AWE) after the administration of contrast gadolinium is a potential biomarker of unstable intracranial aneurysms. While most studies determine AWE subjectively, this study comprehensively quantified AWE in 3D imaging using a ...

Hyperhomocysteinemia induced by excessive methionine intake promotes rupture of cerebral aneurysms in ovariectomized rats. [PDF]

, 2016
BackgroundHyperhomocysteinemia (HHcy) is associated with inflammation and a rise in the expression of matrix metalloproteinase-9 (MMP-9) in the vascular wall.

Treatment of Ruptured Abdominal Aortic Aneurysms: State of the Art

Acta Médica Portuguesa, 2018
Introduction: Endovascular aneurysm repair for ruptured abdominal aortic aneurysm has been increasingly advocated due to short term benefits. Most observational studies point towards survival advantage for endovascular aneurysm repair over open repair ...

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.

Serum amyloid a protein as a potential biomarker in predicting acute onset and association with in-hospital death in acute aortic dissection

BMC Cardiovascular Disorders, 2019
Background Acute aortic dissection (AAD) is a life-threatening disorder in vascular surgery with a high early mortality. Serum amyloid A (SAA) is a kind of acute-phase protein with a rapid diagnostic value in other diseases.

Simulation of hemodynamics in artery with aneurysm and stenosis with different geometric configuration

Journal of Biomechanical Science and Engineering, 2014
In previous published research, the deployment of flow-diversion increases the intra-aneurysmal pressure by 20 mmHg in the case with a pre-aneurysm stenosis. The purpose of this study is to learn the influence to the aneurysm when a pre-aneurysm stenosis
