Area of Science:

  • Regenerative Medicine
  • Transplantation Biology
  • Surgical Innovation

Background:

  • Extracorporeal perfusion of organs has diverse clinical uses, including organ storage, drug delivery, and tissue transfer.
  • A significant limitation in this field is the scarcity of robust experimental models for studying perfusion techniques.
  • Current models often fail to adequately replicate the complexity of human physiological conditions for extended perfusion.

Purpose of the Study:

  • To develop and validate a human extracorporeal free flap perfusion model.
  • To utilize normally discarded abdominoplasty tissue for this novel perfusion system.
  • To assess the feasibility and efficacy of prolonged extracorporeal perfusion of deep inferior epigastric artery perforator flaps.

Main Methods:

  • Development of a perfusion system utilizing an extracorporeal membrane oxygenation (ECMO) device.
  • Acquisition of deep inferior epigastric artery perforator flaps from five patients undergoing abdominoplasty.
  • Sustained extracorporeal perfusion of these flaps for an average duration of six days.

Main Results:

  • Successful establishment of a human extracorporeal free flap perfusion model.
  • Demonstration of sustained perfusion of deep inferior epigastric artery perforator flaps for a mean of six days.
  • Biochemical and pathological assessments indicated the viability and integrity of the perfused flaps (detailed in the article).

Conclusions:

  • The developed extracorporeal perfusion model using ECMO is a viable method for preserving free flaps.
  • This model offers a promising platform for future research in organ preservation, transplantation, and regenerative medicine.
  • Utilizing abdominoplasty waste flaps presents an ethical and practical approach to advancing perfusion research.
