Elastomers three-dimensional biomodels proven to be a trustworthy representation of the angiotomographic images

Biomodelos tridimensionais de elastômero provaram ser uma representação confiável de imagens angiotomográficas

ABSTRACT

Intracranial aneurysm (IA) rupture is responsible for 80% of spontaneous arachnoid hemorrhages and associated with an extremely high mortality rate. Two possible surgical interventions are endovascular embolization and microsurgical clipping. Three-dimensional (3D) prototyping models help in surgical planning minimizing perioperative risks in both methods and reducing operating time.

Methods

3D biomodels were printed with flexible material (elastomer) using angiotomographic DICOM acquired images and compared to 3D digital subtraction angiography (DSA) images.

Results

3D biomodels represented the aneurysm angioarchitecture exactly, especially the neck and domus features.

Conclusion

Elastomers 3D biomodels proved to be a trustworthy representation of the angiotomographic images and could be used to help surgical planning in IA treatment.
