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.
