Use of 3D Prototypes for Complex Surgical Oncologic Cases

Area of Science:

• Biomedical Engineering
• Surgical Oncology
• Medical Imaging

Background:

• Rapid prototyping, or creating physical 3D models from digital versions, is increasingly used in medicine.
• Printing complex anatomical structures, like tumors with major vessels, presents significant technical challenges.
• This study focuses on technological advancements and clinical application of high-fidelity 3D prototypes for challenging tumor cases.

Purpose of the Study:

• To report technological developments in creating high-fidelity 3D prototypes of tumors encasing major vessels.
• To evaluate the clinical implementation and benefits of 3D prototyping in surgical planning for complex oncological cases.
• To assess the impact of 3D printed models on surgical approach, feasibility, and complication management.

Main Methods:

• Three patients with tumors encasing major vessels requiring complex surgery were selected.
• 3D virtual models were generated from routine CT and MRI scans.
• Expert collaboration between a radiologist, surgeon, and CAD engineer was crucial for model creation.

Main Results:

• Surgeons utilized the 3D prototypes for pre-operative practice and planning.
• The 3D models facilitated advance discussion on surgical approach, feasibility, and potential complications.
• All three patients underwent successful surgery as planned, with improved pre-operative understanding.

Conclusions:

• Physical 3D printing of tumors with intricate anatomical relationships is technically achievable.
• Refined surgical planning through 3D prototyping can lead to safer and more complete tumor resections.
• Early clinical experience indicates that 3D prototyping significantly aids surgical oncology planning for complex tumors.
