Splenic rupture and splenectomy in a foal

Summary A 45‐day‐old foal was presented for abdominal pain. Examination revealed the presence of haemoabdomen. An exploratory celiotomy was performed that revealed a large tear on the visceral surface of the spleen. A splenectomy was performed without rib resection. An abdominal wall hernia and leucocytosis had developed by 6 weeks post surgery. A second celiotomy to repair the hernia and explore the cause of the leucocytosis was performed 10 weeks after the first surgery. A portion of the caecum and colon had become adhered to the body wall at the site of the hernia; these areas were resected and the hernia repaired with a polypropylene mesh. The filly made a good recovery and is currently in training. Splenic rupture should be considered in any horse showing signs of abdominal pain with ultrasonographic findings consistent with haemoabdomen.
