Area of Science:

  • Plastic Surgery
  • Microsurgery
  • Surgical Anatomy

Background:

  • Developing robust animal models is crucial for advancing plastic surgery techniques.
  • Training in microsurgery requires models that simulate anatomical challenges.

Purpose of the Study:

  • To describe a new axial-pattern rat skin flap model based on the caudal femoral artery.
  • To evaluate its utility for orthotopic and heterotopic island flap transfers and free-tissue transfers.
  • To provide a challenging model for microsurgical training and skin flap physiology studies.

Main Methods:

  • An axial-pattern rat skin flap was designed based on the caudal femoral artery.
  • Orthotopic and heterotopic island flap transfers were performed.
  • Free-tissue transfers utilizing the common femoral artery were also explored.

  • A nonselective dye injection technique was employed due to the small pedicle size to elevate a large island skin flap.

    • Main Results:

    • The described flap model allows for successful elevation of a large island skin flap based on the caudal femoral artery.
    • The model is suitable for both island flap transfers and free-tissue transfers.
    • The use of nonselective dye injection proved effective for flap elevation in this specific anatomical context.

    Conclusions:

    • This caudal femoral artery-based rat skin flap offers a valuable and challenging alternative model for plastic surgery training.
    • It facilitates the study of skin flap physiology and provides a platform for practicing fundamental microsurgical principles.
