    BackgroundArteriovenous malformations (AVMs) represent a complex pathologic entity in terms of their associated angioarchitecture and blood flow dynamics.MethodsUsing existing imaging data, we generated a patient's giant AVM to scale.ResultsA series of 3-dimensional (3D) models were generated and blood flow dynamics were represented. Faculty and resident surveys were positive regarding the technology.ConclusionsThis report represents a novel application of 3D printing in neurosurgery and a means to model dynamic blood flow in 3 dimensions. The 3D printed models may improve on our ability to plan for and treat complex vascular pathologies.Copyright © 2016 Elsevier Inc. All rights reserved.
