The purposes of this study were: 1) to evaluate a barium (30%) and gelatin (4%) solution as an intravascular radiographic contrast medium when perfused into intact equine cadavers, 2) to determine the most appropriate skin site to harvest a flap with direct cutaneous vasculature, and 3) to identify potential recipent vessels for free‐flap transfer. Heparinized, aspirin‐treated horses were euthanatized, exsanguinated, and perfused with the contrast media. After 24 hours refrigeration, the cadvers were dissected and radiographed. The contrast medium remained solid for the duration of studies (approximately 4 hours), and provided excellent visualization of the arterial vasculature and smaller venous vessls, but did not adequately fill large veins. Due to its location and consistent vascular supply, the skin perfused by branches of the cudal superficial epigastric artery and vein is an appropriate skin‐flap donor site. Multiple potential recipent vessels were identified.
