## Contribution

The use of 3D printed patient-specific vascular models for optimal catheter selection in aneurysm embolization is demonstrated.

## Key findings

- 3D printed models enabled optimal catheter selection in two complex aneurysm cases.
- Preoperative simulations reduced intraoperative catheter exchanges and placement time.
- The approach improved procedural efficiency and outcomes.

## Abstract

Patient-specific vascular models enhance preoperative planning in interventional radiology, particularly in complex and anatomically challenging cases. This report presents two cases of complex aneurysm coil embolization in which three-dimensional, printed, patient-specific vascular hollow models were key to selecting optimal catheters, leading to successful interventions. Preoperative simulations with these models facilitated preselection of the optimal catheter, minimizing the need for intraoperative catheter exchange and reducing the time required for catheter engagement and placement. This approach improves procedural efficiency and outcomes by ensuring a smoother workflow.
