1Sanko Üniversitesi, Beyin ve Sinir Cerrahi Kliniği, Gaziantep, Türkiye Cerebral arteriovenous malformation (AVM) is a most common cause of spontaneous hemorrhage especially in young patients with high mortality and morbidity in each bleeding attack. It is important to determine the risk of bleeding and to assist the management of patient and available treatment due to its frequency in neurosurgery. From past to present various diagnostic methods such as transcranial doppler and 4-dimensional MRG have been used to understand AVM morphology and hemodynamics and to evaluate its relationship with hemorrhage. Although comprehensive results have been identified between AVM morphology and bleeding, the relationship between AVM hemodynamics and bleeding has still not been clearly established. The most important reason is seen as the technical difficulties in the evaluation of hemodynamics and the use of different measurement techniques. In this paper, whetheror not the presence of the relationship between morphologic, hemodynamic factors and hemorrhage risk in patients with AVM will be discussed accompanied by literature review.
