Optimizing cadaveric models for endovascular training through effective preparation techniques.

Area of Science:

• Medical Education
• Surgical Simulation
• Vascular Interventions

Background:

• Cadaveric models are essential for endovascular training.
• Developing high-fidelity models requires meticulous preparation.
• Standardized techniques are needed to ensure reproducibility.

Purpose of the Study:

• To describe a detailed preparation process for fresh frozen cadavers (FFCs).
• To create versatile, high-fidelity cadaveric models for endovascular training.
• To enhance the effectiveness of endovascular procedural training.

Main Methods:

• Two FFCs were thawed and prepared over three days.
• Vascular patency was maintained using a motorized pump and manual perfusion.
• Vascular access was achieved via ultrasound-guided femoral, carotid, and radial/ulnar arteries.
• Procedures simulated included pulmonary thrombectomy and ruptured abdominal aortic aneurysm repair.

Main Results:

• The cadaveric models successfully replicated complex endovascular scenarios.
• High-quality visualization of major and distal arterial branches was achieved.
• Realistic hemodynamics and vascular patency were maintained throughout simulations.

Conclusions:

• Preparing FFCs is a promising method for developing versatile endovascular training models.
• Sharing these preparation techniques facilitates replication by other institutions.
• Optimized FFC models can become essential tools for training future endovascular specialists.
