The Influence of External Carotid Artery Stenoses on Internal Carotid Artery Flow-An Experimental Investigation

Abstract

Restenoses or late occlusions of reconstructed vascular segments maybe related to progression of the underlying arteriosclerosis and inadequate anticoagulation. The kind and the quality of the performed carotid reconstruction, as well, is an important determinant of good results. A model to study the fluid dynamics of native, stenosed and endarterectomized carotid bifurcations was designed. The project was subdivided into two steps:

• 1. Construction of transparent arterial models resembling human extracranial carotid bifurcations as closely as possible.

• 2. Fluid dynamic and tension optical studies in these models to evaluate the hemodynamics of normal, stenosed and desobiliterated carotid artery bifurcations.
