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.
