Area of Science:

  • Transplantation research
  • Organ preservation
  • Vascular surgery

Background:

  • University of Wisconsin (UW) solution is recognized for its efficacy in organ transplantation.
  • Previous studies indicated UW solution's effectiveness in preserving experimental pedicle skin flaps during prolonged ischemia.

Purpose of the Study:

  • To evaluate the preservation capabilities of UW solution in experimental microvascular free flaps.
  • To determine the limits of UW solution's preservation properties, minimizing endothelial clamp damage influence.

Main Methods:

  • Comparison of UW solution against control and lactated Ringer's solution.
  • Utilization in both pedicle and microvascular free flap models in Sprague-Dawley rats.
  • Assessment across varying durations of ischemia.

Main Results:

  • UW solution exhibited superior preservation compared to all other solutions in both flap models.
  • A significant increase in critical ischemia time was observed in UW-treated free flaps versus pedicle flaps.

Conclusions:

  • UW solution offers superior organ preservation for transplantation, particularly in microvascular free flaps.
  • The study highlights UW solution's potential to extend critical ischemia times, enhancing surgical outcomes.
