Summary
This study introduces an affordable and repeatable in vitro microvessel model for practicing microvascular anastomotic techniques. The model effectively simulates small animal vessels using readily available materials, offering a practical training solution.
Area of Science:
- Vascular Surgery
- Surgical Training
- Biomedical Engineering
Background:
- Microvascular anastomotic training is crucial for surgical proficiency.
- Existing training models may be costly, complex, or ethically constrained.
Purpose of the Study:
- To develop a novel, cost-effective, and ethically uncomplicated in vitro perfused microvessel model.
- To provide a realistic simulation for practicing microvascular anastomotic exercises.
Main Methods:
- Explantation of chicken wing arteries and veins (approx. 1 mm diameter).
- Cannulation and mounting of vessels on a platform.
- Perfusion with preserved, expired whole blood using an automatic perfusor.
Main Results:
- The model accurately simulates viable small-animal microvessels.
- The setup is simple, reliable, and repeatable.
- Materials are inexpensive and widely accessible, with no ethical concerns.
Conclusions:
- This in vitro model offers a practical, affordable, and repeatable method for microvascular anastomotic training.
- Human vessels (placenta, omentum) can be adapted for similar training but involve ethical considerations and material scarcity.
