A realistic aneurysm clipping simulation combining 3D-printed and placenta-based models-how I do it.

Area of Science:

• Neurosurgery
• Medical Simulation
• Surgical Training

Background:

• Hands-on training for neurovascular surgery, especially aneurysm clipping, is limited due to the rise of endovascular techniques.
• Existing training models lack realism or present ethical concerns.
• A need exists for accessible, realistic simulation tools for neurosurgical education.

Purpose of the Study:

• To develop and present a novel, cost-effective neurovascular surgical training station.
• To provide a semi-realistic surgical field for practicing aneurysm clipping and related skills.
• To address limitations in current neurosurgical training methods.

Main Methods:

• The training station integrates a 3D-printed skull replica, a silicone brain parenchyma with a Sylvian fissure, and perfused placental vascular layers.
• Placental vasculature is catheterized and perfused to simulate pulsatile blood flow for aneurysm clipping practice.
• The model allows for dissection practice, management of anatomical constraints, and proximal vascular control.

Main Results:

• The developed training station offers a realistic simulation of pulsatile flow and anatomical challenges.
• It enables practice of critical skills including Sylvian fissure dissection and aneurysm clipping under various conditions.
• The model is cost-effective (approx. $200) and has minimal ethical constraints.

Conclusions:

• This novel training station bridges the gap in current neurosurgical education by providing an affordable and realistic simulation tool.
• It allows neurosurgery residents to refine skills for both emergency and elective procedures.
• The station offers a viable alternative for hands-on training, promoting skill development under near-real surgical conditions.
