Late‐onset seizures in a domestic shorthaired cat with global brain ischaemia and cortical laminar necrosis

Abstract
Abstract The most common cause of global brain ischaemia in veterinary species is anaesthesia‐related cardiovascular dysfunction. Both early‐ and late‐onset seizures secondary to ischaemia are well recognised in human medicine, but late‐onset seizures have not been reported in veterinary species. A 2‐year‐old, female, neutered, domestic shorthaired cat with a history of blindness since ovariohysterectomy 10 months previously was presented for investigation of suspected seizure activity over the previous month. Neurological examination localised to generalised diffuse forebrain pathology. Magnetic resonance imaging was consistent with global brain ischaemia and suggestive of cortical laminar necrosis. The clinical history and imaging findings were consistent with historical perioperative cerebral hypoxia. Treatment with phenobarbitone resulted in excellent control of seizures. Anaesthesia accidents can occur during short, ‘routine’ procedures in apparently clinically healthy animals and may have severe long‐term effects for patients. This report suggests that late‐onset seizures can occur as a result of global brain ischaemia in veterinary species.
