Reliable and reproducible murine models for commonly used abdominal plastic surgical flaps

Animal models have been used for many years in surgical research to develop different surgical techniques, improve understanding of anatomy and physiology and hone surgical skills. The benefit of such models has been particularly important in developing relatively young specialties like plastic surgery and many plastic surgical techniques are designed and studied in animals long before they are used in humans. We describe techniques for raising several reliable and reproducible abdominal flaps in rodents, including transverse rectus abdominis myocutaneous flaps in rats and mice, superficial inferior epigastric artery flaps in rats and perforator flaps in rats. The intention of this paper is to act as a point of reference for any microvascular or plastic surgeon who is planning to perform abdominal plastic surgical flap research or further microvascular skills.
