Biomechanical wall properties of human intracranial aneurysms resected following surgical clipping (IRRAs Project).
BACKGROUND AND PURPOSE Individual rupture risk assessment of intracranial aneurysms is a major issue in the clinical management of asymptomatic aneurysms. Aneurysm rupture occurs when wall tension exceeds the strength limit of the wall tissue. At present, aneurysmal wall mechanics are poorly understood and thus, risk assessment involving mechanical properties is inexistent. Aneurysm computation...

At present, aneurysmal wall 42 mechanics are poorly understood and thus, risk-assessment involving mechanical properties is 43 inexistent. Addi...
متن کاملcomparison of endovascular coiling and surgical clipping for the treatment of intracranial aneurysms: a prospective study.
background: management of intracranial aneurysms has made debates about the best treatment modality in recent years. the aim of this study was to compare the interventional outcomes between two groups of patients, one treated with endovascular coiling and the other treated with surgical clipping. methods: this prospective study included 48 patients with intracranial aneurysms who underwent endo...
متن کاملRecurrent intracranial aneurysms after successful neck clipping.
BACKGROUND To report the authors' experience with recurrent aneurysms after primarily completely clipped cerebral aneurysms and discuss mechanisms of recurrence and recommended management. METHODS Data were available for 1016 consecutive patients who underwent clipping of ruptured and unruptured aneurysms in a 15-year period from 1993-2007. RESULTS Nine patients were treated for recurrent a...
متن کاملWall Mechanical Properties and Hemodynamics of Unruptured Intracranial Aneurysms.
BACKGROUND AND PURPOSE Aneurysm progression and rupture is thought to be governed by progressive degradation and weakening of the wall in response to abnormal hemodynamics. Our goal was to investigate the relationship between the intra-aneurysmal hemodynamic conditions and wall mechanical properties in human aneurysms. MATERIALS AND METHODS A total of 8 unruptured aneurysms were analyzed. Com...
