[Congenital porto-phrenico-pulmonary shunt in a cat]

An 8-month-old castrated male Birman showing hematuria, stranguria, and intermittend head tremor was presented for further diagnostic work-up on suspicion of hepato-encephalopathic syndrome. Computed tomography examination revealed a shunt vessel emanating from the vena gastrica sinistra which connected to both the vena phrenica sinistra and a pulmonary vessel from the left caudal lung lobe draining into the left atrium. This represents the first case report describing the radiologic appearance, surgical ligation as well as the post-operative outcome of a cat with such a shunt form.
