Intracranial aneurysm surgery aided by 3D printed model

Case Study
  • Neurosurgery


A 77-year-old female presented with a large basilar arterial aneurysm. The CT images used made it difficult to conceptualize the size of the vessel and the proximity of the vessel to other surrounding arteries.

The CT images were used to create a 1:1 scale flexible model of the aneurysm and surrounding anatomy. The model was used to plan the exact trajectory of the catheter stent deployment. The stent was also measured against the 3D printed model prior to surgery.


The clinicians had an improved diagnosis of the intracranial aneurysm and used the model to create an exact plan ahead of surgery. This resulted in a substantial reduction of risk for misplacement or wrong stent being used, drastically improving outcomes for the patient.
