Abstract

A technique for performing digital venography in the standing horse R. F. REDDEN PO Box 507, Versailles, Kentucky 40383, USA. Introduction Laminitis in horses is a potentially devastating condition. Regardless of the inciting event, displacement of the third phalanx is often associated with alterations in the digital vasculature which can have a profound impact on the outcome (Hood et al. 1994; Grosenbaugh et al. 1999). Hood et al. (1994) demonstrated a range of perfusion defects in the solar, submural (lamellar) and coronary vasculature of horses with chronic laminitis, with the defects tending to be more numerous and severe in horses considered refractory to treatment than in those considered treatable. The clinical outcome in horses with laminitis is greatly influenced by the veterinarian’s ability to evaluate accurately the damage to the digital structures (Redden 1997). Rotation or vertical displacement (‘sinking’) of the third phalanx can be identified and quantified using routine radiography. However, this imaging modality on its own does not provide information about the digital vasculature. Various in vivo methods of assessing digital perfusion have been reported in laminitic horses.
