Summary
Simulation case rehearsals using patient-specific data for carotid artery stenting show excellent validity. While predicting vessel cannulation difficulty, simulations struggled with post-stent angulation changes, indicating potential but requiring further cost-benefit analysis.
Area of Science:
- Endovascular Surgery
- Medical Simulation
- Cardiovascular Interventions
Background:
- Carotid artery stenting (CAS) is a complex endovascular procedure.
- Pre-procedural planning is crucial for optimizing CAS outcomes.
- Virtual reality simulation offers a potential tool for surgical training and planning.
Purpose of the Study:
- To assess the utility of patient-specific simulation case rehearsals for carotid artery stenting (CAS).
- To evaluate the face and content validity of endovascular simulator-based rehearsals.
- To determine the predictive capability of simulations for procedural challenges.
Main Methods:
- A case series of 5 patients undergoing CAS was studied.
- Patient-specific computed tomography angiography (CTA) data were used to create simulation cases.
- Simulations were performed on an endovascular simulator.
- Subjective surveys assessed the validity of the simulations.
Main Results:
- Simulated and operative device dimensions were comparable.
- Subjective surveys reported excellent face and content validity for the simulations.
- Simulations accurately predicted difficulty with vessel cannulation.
- Simulations had difficulty predicting post-stent changes in bifurcation angulation.
Conclusions:
- Patient-specific CTA-derived data can feasibly create realistic case rehearsal simulations for CAS.
- Simulation case rehearsals demonstrate high validity for procedural elements like vessel cannulation.
- Further research is needed to determine the overall utility and cost-benefit of this simulation approach for CAS.
