Solitonic Windkessel Model for Intracranial Aneurysm
Brain Sciences, 2022 The Windkessel model, which is known as a successful model for explaining the hemodynamic circulation, is a mathematical model with a direct correspondence with the electric circuit.

Biomechanical Modeling of Cerebral Aneurysm Progression to Estimate Rupture Risk
Biomechanics, 2023 A cerebral aneurysm is a medical condition described as the bulging out of the cerebral artery under adverse pressure conditions. Patients with such medical conditions have a mortality of 20% and additional morbidity of 30–40% due to aneurysm rupture ...

BMJ, 1973 A reappraisal of case histories of patients with ruptured intracranial aneurysms emphasized the importance of clinically recognizing severe spasm that contraindicates early angiography and large cerebral haematomas that require immediate evacuation. Observation from the day of haemorrhage is important; most recurrent episodes with cerebral signs in the

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 ...

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 ...

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 ...

Outcome after surgical repair of sealed rupture abdominal aortic aneurysms: a case-control study [PDF]
Clinics, 2006 OBJECTIVE: To establish, in a case-control study, the early mortality and long-term survival after surgical correction of sealed rupture abdominal aortic aneurysm, compared to controls who underwent standard, nonruptured abdominal aortic aneurysm repair.
