Pseudohyperkalemia after total splenectomy in a dog: a case report

초록

A 16-year-old, 7.4 kg, castrated male Cocker Spaniel presenting anorexia and weight loss was referred due to a splenic mass, and total splenectomy was performed to resolve clinical signs. Following surgery, the dog developed mild hyperkalemia (6.27 mmol/L) without any clinical symptoms. Further investigations were conducted to determine the cause of hyperkalemia. The serum-plasma potassium difference was measured (1.05 mmol/L), and pseudohyperkalemia was diagnosed. The cause of pseudohyperkalemia was considered as thrombocytosis after splenectomy. The dog did not receive any specific treatment to lower blood potassium. To our knowledge, we report the first case of post-splenectomy pseudohyperkalemia in a dog. © 2022 Korean Society of Veterinary Science. All rights reserved.
