Companion Cat Hyperthyroidism Surgical Treatment

Surgical thyroidectomy can cure feline hyperthyroidism permanently but requires careful patient selection and perioperative management.

Key Facts

Thyroidectomy removes one or both thyroid glands to eliminate the source of excess thyroid hormone
Success rates for permanent cure of hyperthyroidism are high in carefully selected cases
The main risk is damage to adjacent parathyroid glands causing hypocalcaemia post-operatively
Hypothyroidism requiring supplementation may occur if both glands are removed
Thyroidectomy avoids lifetime medication compliance but carries surgical and anaesthetic risks
Cardiac assessment before anaesthesia is essential in hyperthyroid cats

Welfare Considerations

Surgical treatment offers a permanent resolution to feline hyperthyroidism welfare burden in appropriate candidates. The welfare benefit of eliminating daily medication stress must be weighed against surgical risk in individual patients. Close post-operative monitoring for hypocalcaemia is essential to prevent a severe welfare complication.
