Abstract

Imaging anomalies of the great vessels has traditionally been accomplished using conventional biplane modalities as well as three-dimensional (3D) video displays. Our aim was to review the use of stereolithography to create 3D models to assess coarctation of the aorta and vascular rings. Twelve patients had high-resolution CT scans to evaluate anomalies of the great arteries (coarctation: 9, vascular ring: 3). Ages were 19 days to 29 years and weights were 3.3 to 139 kg. Digital dicom data from each scan were converted by a commercially available software package into a 3D digital image. The area of interest was selected and the image was exported to a 3D stereolithographic printer to create a 3D model. The models were then evaluated and the results compared to catheterization and surgical findings. All models accurately displayed the pathology investigated. All 3 of the vascular ring models correlated with surgical findings (double arch: 2, pulmonary sling: 1). Models of aortic coarctation allowed clear depictions of discrete narrowing as well as arch hypoplasia and tortuosity. Stereolithography can create realistic 3D models that accurately display aortic pathology and add important additional information, which may have implications regarding surgical and transcatheter interventions and may also be useful teaching tools for parents and students.
