This study describes an experimental animal model for the investigation of the vascularization of the rectus abdominis muscle and musculo-cutaneous flap on pig. We used four common breed pigs divided in two groups, one muscular and another musculo-cutaneous, each group contained four flaps, .The flaps were harvested, injected with contrast media and studied by radiological methods. The results consist in creating a protocol for harvesting, preparation and radiological investigation of the vascularization, allowing the visualization of epigastric inferior and superior networks, the connections between them and the fascio-cutaneous perforator vessels. We concluded that the experimental animal model proposed is reproducible and is a useful tool in the experimental researches on flaps vascularization.
