Comparative Assessment of Biomechanical Parameters in Subjects With Multiple Cerebral Aneurysms Using Fluid--Structure Interaction Simulations [PDF]
ASME J. Biomech. Eng. 145(5) 051003 (2023), 2022 Cerebral aneurysm progression is a result of a complex interplay of the biomechanical and clinical risk factors that drive aneurysmal growth and rupture. Subjects with multiple aneurysms are unique cases wherein clinical risk factors are expected to affect each aneurysm equally, thus allowing for disentangling the effect of biomechanical factors on ...

Fluid-structure instability forecasts thoracic aortic aneurysm progression [PDF]
Nat. Biomed. Eng 7, 1614-1626 (2023), 2021 The basic mechanism driving aneurysm growth is unknown. Currently, clinical diagnosis of an aneurysm is mainly informed by retrospective tracking of its size and growth rate. However, aneurysms can rupture before reactive criteria are met or remain stable when they are exceeded.

Aneurysm growth and de novo aneurysms during aneurysm surveillance [PDF]
Journal of Neurosurgery, 2016 OBJECTIVE Many low-risk unruptured intracranial aneurysms (UIAs) are followed for growth with surveillance imaging. Growth of UIAs likely increases the risk of rupture. The incidence and risk factors of UIA growth or de novo aneurysm formation require further research. The authors retrospectively identify risk factors and annual risk for UIA growth or

Ten-year analysis of saccular aneurysms in the Barrow Ruptured Aneurysm Trial.
Journal of Neurosurgery, 2020 OBJECTIVEThe authors present the 10-year results of the Barrow Ruptured Aneurysm Trial (BRAT) for saccular aneurysms. The 1-, 3-, and 6-year results of the trial have been previously reported, as have the 6-year results with respect to saccular aneurysms.

From aneurysm to aneurysmal vasculopathies [PDF]
Operative Techniques in Neurosurgery, 1999 Intracranial aneurysms (AA) as a source of cerebral haemorrhage affect the patient's vital, functional prognosis, and represent one of today's medical challenges. Many articles and studies on aneurysms have been published in highly technical journals (neurosurgical, neuro- radiological, neurological) but also in journals of general interest, such as ...

Cellular Mechanisms of Aortic Aneurysm Formation.
Circulation Research, 2019 Aortic aneurysms are a common vascular disease in Western populations that can involve virtually any portion of the aorta. Abdominal aortic aneurysms are much more common than thoracic aortic aneurysms and combined they account for >25 000 deaths in the ...

Open versus Endovascular Repair of Abdominal Aortic Aneurysm.
New England Journal of Medicine, 2019 BACKGROUND Elective endovascular repair of an abdominal aortic aneurysm results in lower perioperative mortality than traditional open repair, but after 4 years this survival advantage is not seen; in addition, results of two European trials have shown ...

Arteriosclerosis, Thrombosis and Vascular Biology, 2019 Aortic aneurysm is a vascular disease whereby the ECM (extracellular matrix) of a blood vessel degenerates, leading to dilation and eventually vessel wall rupture.

Extracellular matrix, regional heterogeneity of the aorta, and aortic aneurysm
Experimental and Molecular Medicine, 2019 Aortic aneurysm is an asymptomatic disease with dire outcomes if undiagnosed. Aortic aneurysm rupture is a significant cause of death worldwide. To date, surgical repair or endovascular repair (EVAR) is the only effective treatment for aortic aneurysm ...

H19 Induces Abdominal Aortic Aneurysm Development and Progression
Circulation, 2018 Background: Long noncoding RNAs have emerged as critical molecular regulators in various biological processes and diseases. Here we sought to identify and functionally characterize long noncoding RNAs as potential mediators in abdominal aortic aneurysm ...
