Treating Feline Hyperthyroidism |
|||||
Hyperthyroidism, the most commonly diagnosed endocrinopathy in cats is usually caused by a benign andenoma of the thyroid gland. In 70% of cases, the condition is bilateral. Involvement of intrathoracic thyroid tissue can also occur. The Barton Veterinary Hospital offers the ideal referral facility for radioactive iodine (I131) treatment of this condition. Surgery often involves a considerable anaesthetic risk and post operative complications are common, especially if bilateral thyroidectomy occurs very frequently. Medication compliance can be poor since twice or three times daily dosage for the duration of the cat’s life is usually needed. Some cats vomit frequently or develop skin lesions as a side effect of medical treatment.

The Barton Veterinary Hospital has been carrying out this form of treatment in our specially designed and licensed unit for more than four years. We have now treated approximately 600 cats. Treatment normally involves a single subcutaneous injection of radioisotope and involves a period of hospitalisation for public health reasons usually lasting 14 to 28 days. This depends on this level of gamma emissions which we can measure – thus keeping the period “away from home” to a minimum. Pre-operative investigations would normally include a serum biochemistry screen, T4 assay, urinalysis and thoracic radiography if these have not been carried out within three to four weeks of admission. All cats must be fully vaccinated and have had a recent booster injection within the preceding 12 months.
