Abstract | The presence of wall vibrations of relatively high frequencies (several hundreds of Hz) on the top of intracranial aneurysms have been reported in the 70’s from open brain surgery measurements [1]. Later study [2], based on non-invasive recordings, provided additional evidences for charateristic high frequencie intracranial blood flow sounds associated with the presence of aneurysms. It is only recently that computational and experimental in-vitro studies modelled turbulent-like blood flow environments within intracranial vasculature, with characteristic fluctuations in the order of 100-300 Hz ([3, 4]). However, the link between unstable blood flow and arterial wall vibrations within intracranial aneurysms still remains speculative and is the focus of the present work. |
