Abstract
BACKGROUND: Arteriovenous malformations (AVMs) represent a complex pathologic entity in terms of their associated angioarchitecture and blood flow dynamics. METHODS: Using existing imaging data, we generated a patient's giant AVM to scale. RESULTS: A series of 3-dimensional (3D) models were generated and blood flow dynamics were represented. Faculty and resident surveys were positive regarding the technology. CONCLUSIONS: This 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.
