Case Report: long-term calcaemia management in a dog after thyroidectomy and parathyroidectomy.

Abstract

This report describes a canine case of severe hypocalcaemia following the surgical removal of a thyroid lobe and the ipsilateral parathyroid glands for thyroid carcinoma. After initial stabilisation with intravenous calcium gluconate, the dog was initially managed with a commercial diet, and subsequently with a homemade diet, which provided 3.72 and 3.30 g/1,000 kcal ME of calcium, 376 and 295 IU of vitamin D3, and 2.48 and 1.50 g/1,000 kcal metabolisable energy (ME) of phosphorus, respectively. Both nutritional plans were supplemented with calcium carbonate (200 mg/day) and calcitriol (9.84 IU/day) to maintain normocalcaemia. A tailored, homemade diet was formulated to address the onset of hyporexia. The patient maintained stable serum calcium, phosphorus, and total 25(OH) vitamin D concentrations over a mid-term follow-up period of 6 months.
