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.

RESUMO

A ruptura dos aneurismas intracranianos é responsável por 80% das hemorragias subaracnóideas espontâneas e está associada a uma taxa de mortalidade extremamente alta. Duas intervenções cirúrgicas viáveis são embolização endovascular e clipagem microcirúrgica. Os modelos de prototipagem tridimensional (3D) auxiliam no planejamento cirúrgico e na diminuição dos riscos intra-operatórios nos dois procedimentos e redução do tempo da cirurgia.

Métodos Foram impressos biomodelos em 3D com material flexível (elastçmero) utilizando imagens DICOM de angiotomografia e comparados com imagens de angiografia por subtração digital em 3D (DAS).

Resultados Biomodelos em 3D representam com exatidão a angioarquitetura do aneurisma, particularmente os detalhes do colo e domus.

Conclusão Biomodelos em 3D com elastçmeros mostraram ser uma representação confiável das imagens angiotomográficas, podendo ser utilizados no planejamento cirúrgico no tratamento de IA.
