Summary
Silicone vascular models enhance neurosurgical training. Residents showed improved performance and safety in diagnostic angiography procedures after using these models, with reduced procedure and fluoroscopy times.
Area of Science:
- Neurosurgery
- Medical Simulation
- Endovascular Procedures
Background:
- Neurosurgical training increasingly relies on simulation.
- Evaluating the efficacy of simulation tools is crucial for improving trainee skills and patient safety.
Purpose of the Study:
- To assess if silicone vascular models improve trainee performance and safety in neuroendovascular procedures.
- To determine the impact of simulation on diagnostic angiography training.
Main Methods:
- Ten neurosurgery and radiology residents performed diagnostic angiograms on silicone vascular models.
- Procedures were conducted in an angiography suite using biplane fluoroscopy.
- Trainee performance was evaluated based on technique, procedure time, and fluoroscopy time, with varying levels of faculty coaching.
Main Results:
- Overall procedure time decreased significantly from 51 to 42 minutes (p=0.01).
- Total fluoroscopy time significantly decreased from 12 to 9 minutes (p=0.002).
- Technical skills in navigation, vessel selection, projection setup, and roadmap usage showed significant improvement.
Conclusions:
- Silicone vascular models provide valuable training experience in diagnostic angiography.
- Simulation using these models in a clinical setting improves resident performance and safety.
- This training method is effective for developing essential neuroendovascular skills.
