Hold me, turn me: 3D printed models help doctors rehearse tricky cerebrovascular procedures

Vein of Galen-3D-20140418_Orbach-croppedFour children with life-threatening malformations of blood vessels in the brain appear to be the first to benefit from 3D printing of their anatomy before undergoing high-risk corrective procedures.

The children, ranging from 2 months to 16 years old, all posed particular treatment challenges: cerebrovascular disease often entails complex tangles of vessels in sensitive brain areas.

“These children had unique anatomy with deep vessels that were very tricky to operate on,” says Boston Children’s neurosurgeon Edward Smith, MD, senior author of the paper and co-director of the hospital’s Cerebrovascular Surgery and Interventions Center. “The 3D-printed models allowed us to rehearse the cases beforehand and reduce operative risk as much as we could. You can physically hold the 3D models, view them from different angles, practice the operation with real instruments and get tactile feedback.”
