The contents of the page have been created to stimulate discussion on the natural history of arteriovenous malformation and clinical decisions should not be made based on any part of this web-page. The 'AVM Calculator' is for use by only neurosurgeons, neuroradiologists and radiotherapist with particular interest in managing patients with arteriovenous malformation. The AVM calculator was progammed based on the findings of Ondra et al (Ondra SL, Troupp H, George Ed, Schwab K. The natural history of symptomatic arteriovenous malformations of the brain: a 24-year follow-up assessment. J Neurosurg 73: 387-391, 1990) and the multiplicative law of probability formula outlined by Kondziolka D et al [Kondziolka D, McLaughlin MR, Kestle JRW. Simple Risk Predictions for Arteriovenous Malformation Hemorrhage. Neurosurgery, 1995; Volume 37(5): 851-855]. Therefore, please refer to the original papers and make your own critical appraisal of the limitations of the results of the calculation.
