Hemodynamic assessment and computation on vertebral artery stenosis.

Cerebral vascular diseases are associated with cerebral hemodynamic parameter, which is difficult to observe and examine. This paper has proposed a new modeling method based on network and hemodynamics. The harmonic solution to the 18 branches of the circle of Willis is acquired through the plane network. We use this method to explain the development processes of vertebral artery diseases, and the hemodynamic assessment of vertebral artery stenosis have been done to prove this method.
