3.3.7 Dependent oedema
Signs of dependent oedema may be associated with CHF or a number of other conditions. Oedema is most often found in the distal limbs and ventral abdomen (Figure 3.2). In males, the prepuce may fill with fluid. The finding of dependent oedema due to cardiac disease is a poor prognostic indicator, so it is important to rule out other potential causes. Differential diagnoses in this situation are sumin Table 3.3. Mild degrees of filling of the distal limbs and sheath are common in normal horses which are inactive, and can also be affected by diet.
