Rat tail vessels offer a superior, economical alternative for microvascular training, providing ample length and appropriate diameters for practicing anastomoses, especially for vessels under 0.5 mm.

Area of Science:

  • Veterinary Anatomy
  • Surgical Training Models
  • Vascular Surgery

Background:

  • The rat femoral vessel model is a common but limited choice for microvascular training.
  • Existing models lack sufficient anastomoses and vessel size variety.

Purpose of the Study:

  • To introduce and describe the rat tail vessel model as an improved alternative for microvascular surgical training.
  • To highlight the anatomical and practical advantages of using rat tail vessels.

Main Methods:

  • Detailed description of the anatomy of rat tail vessels.
  • Explanation of the dissection and preparation techniques for practicing microvascular anastomoses.
  • Utilizing frozen rat tails from other projects for enhanced convenience and cost-effectiveness.

Main Results:

  • Rat tail vessels offer significant length and diameters ranging from 1 mm to 0.2 mm.
  • This model is particularly suitable for practicing anastomoses on vessels smaller than 0.5 mm.
  • The use of frozen, readily available tails enhances practicality and frugality.

Conclusions:

  • The rat tail vessel model is an ideal, economical, and convenient choice for microvascular training.
  • It surpasses the rat femoral model in terms of vessel availability and suitability for smaller vessel anastomoses.
  • This model provides a valuable resource for surgical skill development in microvascular techniques.
