Summary
This study evaluated silicone and animal models for simulating endovascular procedures. Conventional silicone models closely replicated anatomy but offered high resistance in curved vessels.
Area of Science:
- Biomedical Engineering
- Medical Simulation
- Neuroendovascular Surgery
Background:
- Endovascular procedures require realistic models for training.
- Current models may lack anatomical accuracy or tactile feedback.
- Evaluating novel simulation materials is crucial for surgical skill development.
Purpose of the Study:
- To assess the fidelity of conventional silicone, silicone suture, and animal vascular models for endovascular procedure simulation.
- To compare the anatomical accuracy and tactile feedback of different model types.
- To evaluate the utility of these models in a digital subtraction angiography (DSA) controlled training system.
Main Methods:
- Production of conventional silicone, silicone suture, and animal vascular (pig) models based on clinical imaging.
- Integration of models into a training system with portable DSA control.
- Evaluation of anatomical reproduction, device manipulation resistance, and procedural outcomes (e.g., dilation).
Main Results:
- Conventional silicone models offered excellent anatomical detail but high resistance in curved vessels.
- Silicone suture models facilitated giant aneurysm modeling but had inaccurate dome projection.
- Animal vascular models provided realistic tactile feedback but lacked precise anatomical accuracy.
- Stroke models showed insufficient dilation with angioplasty or stenting.
Conclusions:
- Conventional silicone models provide superior anatomical fidelity for neurovascular structures.
- Animal models offer more realistic tactile feedback for endovascular device manipulation.
- Further refinement of silicone models is needed to balance anatomical accuracy and realistic tactile resistance for comprehensive endovascular training.
