Summary
This study introduces a straightforward mouse model for super-microsurgery training. The developed model effectively demonstrates vascular anastomosis of the mouse middle caudal artery, proving useful for surgical skill development.
Area of Science:
- Veterinary Medicine
- Surgical Training
- Microsurgery
Background:
- Super-microsurgery requires specialized training models.
- Developing practical and accessible models is crucial for surgical education.
Purpose of the Study:
- To establish a simple and practical model for super-microsurgery training.
- To utilize the middle caudal arteries of Kunming mice for this model.
Main Methods:
- A ⊔-shaped incision was made to expose the mouse middle caudal artery and accompanying veins.
- The artery was transected and anastomosed end-to-end using 12-0 microsutures.
- The procedure was performed on Kunming mice.
Main Results:
- The mouse middle caudal artery is superficially located and anatomically constant.
- Immediate postoperative patency after vascular anastomosis was 100%.
- Postoperative patency rates were 100% at 24h, 80% at 3 days, and 75% at 1 week.
Conclusions:
- The mouse middle caudal artery model is suitable for super-microsurgery training due to its accessibility and constant anatomy.
- The model facilitates training in vascular anastomoses on small-caliber vessels.
- The model proved effective with high patency rates in initial trials.
