Review paper: Cerebral Arteriovenous Malformations Modeling

The Cerebrovascular system is characterized by complex interactions between various control mechanisms and physiological processes. Different approaches are used to provide better diagnostics and physiological under-standing and medical planning. The mathematical description and modeling of the human cerebrovascular system plays nowadays an important role in the comprehension of the genesis and development of cerebrovascular disorders by providing computer based simulation of dynamic processes. Intracranial Arteriovenous malformations (AVM) constitute usually congenital vascular anomalies of the brain. AVMs are composed of complex connections between the arteries and veins that lack an intervening capillary bed. A brain AVM (BAVM) is a set of abnormal vessels comprising feeding arteries; draining veins and a collection of arterialized veins called the Nidus. The AVM model with vessel dilation is more similar to clinical observations than those without vessel dilation. In this paper, we reviewed various types of simulations / Modeling suggests the physician that models are useful tools to study hemodynamic problems of the cerebral circulation. This review paper on modeling is created from the acquired images from CTA, and MRA AND DSA and also how the model help the doctors to make diagnostic and therapeutic decisions to avoid brain hemorrhage. This paper aims to give an overview on lumped parameter models that have been developed by many researchers all over the world, to simulate the blood flow in systemic arteries. Surveying various references we make a review of different approaches to arterial tree modeling and discuss on the applications of such models.
