Human vessels for microsurgery training can be reused multiple times after freezing and thawing. This technique preserves vascular integrity for up to four years, offering a sustainable solution for surgical skill development.

Area of Science:

  • Surgical Education
  • Microsurgery Techniques
  • Vascular Biology

Background:

  • Microsurgery training requires human vessels, but suitable lengths are often scarce.
  • The reusability of human vessels for microsurgical training has not been previously investigated.

Purpose of the Study:

  • To evaluate the feasibility of long-term storage and reuse of human vessels for microsurgery training.
  • To assess the structural integrity of preserved human vessels for vascular anastomosis practice.

Main Methods:

  • Human vessels were harvested from discarded tissues obtained during lymph node dissection.
  • Vessels were preserved by freezing and subsequently thawed using hot water for training.
  • Gross and histological examinations were performed to evaluate vessel quality after preservation.

Main Results:

  • Repeated vascular anastomosis training was successfully performed using the same human vessels after multiple freeze-thaw cycles.
  • Preserved human vessels maintained acceptable gross appearance and histological findings for up to approximately four years.
  • The technique demonstrated the potential for long-term storage and reuse of vascular tissue.

Conclusions:

  • Freezing and thawing human vessels is a viable method for microsurgery training.
  • This approach provides a sustainable and accessible resource for developing microsurgical skills.
  • The presented technique supports long-term reuse of human vessels, closely simulating real surgical conditions.
