A new experimental reversed-flow flap model: tail artery based skin flap on the dorsum of the rat.
Reversed-flow flaps are widely preferred particularly in reconstruction of the defects of distal part of the extremities. To overcome the drawbacks faced during clinical practice of this flap type, experimental models in economical species are required. This study provides a new reversed-flow flap model on the dorsum of the rat which is supplied by the ipsilateral lateral caudal artery. It is designed as a triangle with a 4-cm long base and 5 cm long height and it is well protected from autocannibalization and environmental conditions because of its dorsal location. When compared with the present models, we believe that this simple, reproducible, and practical flap model can be considered as advantageous, and will be preferred by the researchers for future experimental studies in hemodynamics and physiology of reversed-flow flaps.
