A simple yet effective training model for mastering deep bypass procedures.

Area of Science:

• Neurosurgery
• Microsurgery
• Surgical Education

Background:

• Neurosurgical bypass skill acquisition requires extensive repetition.
• Current training models are inadequate for deep bypasses and skull base corridors.
• Realistic simulation setups are often complex and costly.

Purpose of the Study:

• To present a novel, simple, and realistic training concept for deep neurosurgical bypasses.
• To enable unlimited practice of deep anastomoses.
• To address limitations of conventional training methods.

Main Methods:

• Utilized a binocular microscope, inexpensive microsurgical instruments, and chicken wing vessels.
• Adapted a commercially available 3D brain-skull model for microanastomosis training.
• Simulated deep neurosurgical bypasses by anastomosing chicken vessels within the model.

Main Results:

• Successfully replicated complex bypasses including STA-PCA, PCA-SCA, and A1-graft-MCA.
• Achieved high realism with a simple and affordable setup.
• No comparable training method in terms of realism, simplicity, and cost was found in existing literature.

Conclusions:

• A cost-effective, straightforward, and realistic training approach for high-frequency individual practice of deep bypasses is presented.
• The method's simplicity allows for replication in resource-limited settings.
• Enhances neurosurgical training for deep bypass procedures.
