Lymph flow determination in the equine hindlimb: Lymphoscintigraphic function studies

The horse frequently shows idiopathic primary lymphoedema or secondary lymphoedema following trauma or infection to its limbs. Lymphoedema develops if the balance between the amount of lymphatic fluid and capacity of lymphatic transport is disturbed. Scintigraphy appears to be the only in vivo technique to evaluate lymphatic transport capacity. The aim of this study was to develop an evaluation technique to determine the lymph flow in the hindlimb of the horse. This technique might show potential to extend the possibilities for investigating disorders of the lymphatic system in equine extremities.
