Background: Feline hyperthyroidism is the most common endocrine disorder in cats. Cats may not reach the disease control and/or have side effects with medical therapy. Thyroidectomy is a definitive treatment and the only option when radioactive iodine is not available. Extracapsular thyroidectomy with transplantation of the external parathyroid gland is the surgical technique that minimizes the risk of postoperative hypocalcemia when it is compared to others. The aim of this study is report the difficulty in visualizing parathyroid gland during extracapsular thyroidectomy with transplantation of the external parathyroid gland technique in hyperthyroid cats.Materials, Methods & Results: Thirty hyperthyroid cats were evaluated and submitted to extracapsular thyroidectomy with transplantation of the external parathyroid gland. Blood samples were collected to hematologic, biochemical and hormonal (total thyroxine) analysis. On physical examination, at least one cervical thyroid lobe was palpable. Cats were treated with methimazole. Thyroidectomy was recommended when adverse effects of medication occurred or medical hormonal stabilization was not achieved. The excised thyroid and a sample of external parathyroid gland were histologically examined. Thirteen castrated males and seventeen spayed female cats in age ranging from eight to nineteen years (mean age 13.3 years) were indiTexto completo
