Portosystemic vascular anomalies are well documented in small animals as is their diagnosis, medical, and surgical management. However in the large animal species there are only a few documented cases of portosystemic shunts. In previous literature there have only been five reported cases of calves with congenital portosystemic shunts and four foals. Surgical attempts were made in two of the calf cases and three of the foal cases. This will report the clinical signs, diagnostics, and medical management used in a calf with a congenital portosystemic vascular anomaly. It will also discuss the clinical signs, diagnostics and treatments used as compared to those previously reported.
