Clinical approach to a rare case of hydrallantois in bitch

Abstract

The present case describes the clinical, sonographic and histopathological findings of hydrallantois in bitch. After 55 days of the first mating, nulliparous Golden Retriever bitch was presented with a primary complaint of perceptible abdominal distension and dyspnoea for the last 3‒4 days. Ultrasonography revealed marked uterine distension with well appreciable anechoic to hypoechoic allantoic regions along with fetal stress. During caesarean section, a cumulative 2.75 L of placental fluid was recovered from allantoic portion with an altered electrolyte profile in comparison to maternal plasma. The histopathology examination of one fetal kidney corroborated tubular degeneration, suggesting nephrosis to be the concomitant aetiology. In conclusion, the clinical examination and ultrasonography provided provisional diagnosis of the condition; caesarean section proved to be an ideal option in order to prevent the dystocia or any other complication during whelping in a bitch even if none of the puppies survived. This approach, with supportive therapy ensures comprehensive care post‐treatment.
