COMPARISON OF THE PERFORMANCE OF NOVEL ENDOVASCULAR TREATMENT TECHNIQUES FOR CEREBRAL ANEURYSMS

Summary Cerebral aneurysms result from a complex interplay between mechanical stresses and pathophysiological changes occurring in the arterial wall. In order to reduce the hemodynamic forces acting on the aneurysmal wall, new endovascular treatments have been developed involving the exclusion of the aneurysm from the intracranial circulation. A comparative study of the performance of three of these techniques is reported here. Digital Particle Image Velocimetry (DPIV) is used to perform in vitro measurements of the velocity and stress fields inside a model of cerebral aneurysms. BACKGROUND ON CEREBRAL ANEURYSM
