A Comprehensive Training Model for Simulation of Intracranial Aneurysm Surgery Using a Human Placenta and a Cadaveric...

Area of Science:

• Neurosurgery
• Surgical Simulation
• Anatomy Education

Background:

• Aneurysmal surgery demands significant surgeon experience for successful outcomes.
• Training neurosurgeons in complex vascular procedures presents challenges.
• Cadaveric models offer high anatomical fidelity for surgical training.

Purpose of the Study:

• To introduce a comprehensive simulation model for aneurysm clipping surgery training.
• To evaluate the realism and utility of a placenta-based simulation model.
• To assess the effectiveness of this model for developing microsurgical skills.

Main Methods:

• A simulation model was developed using prepared and perfused human placentas within cadaveric specimens.
• Aneurysms were created in placental arteries via catheterization.
• Ten neurosurgery residents/attendees performed simulated aneurysm clipping and provided feedback.

Main Results:

• The simulation demonstrated high realism in skin incision, muscle dissection, and craniotomy.
• Vascular management and closure phases were rated as realistic.
• Participants found the model valuable for training, though brain tissue emulation was less realistic.

Conclusions:

• This simulation model provides a valuable tool for training in unruptured aneurysm clipping.
• The model effectively replicates key aspects of neurosurgical aneurysm procedures.
• The placenta-based simulation is recommended for standard neurosurgical training curricula.
