Hyperthyroidism In Cats Treatment Radioactive Iodine

Here is the study on low dose radioiodine treatment.

Hyperthyroidism in cats treatment radioactive iodine.

Following the subcutaneous injection the patient is hospitalized in our nuclear medicine ward and monitored around the clock via closed circuit cameras and twice daily staff care for 4 days until the levels of radiation emitted are below acceptable levels. However that may not be the case in a very small number of cats. The majority of cats treated with radioactive iodine have normal hormone levels within one to two weeks of treatment. It is as easy as one injection just under the skin much like a routine feline vaccine.

There are many advantages to radio iodine treatment for example it is non invasive painless. Patients that continue to have high levels of thyroid hormones by 3 months after the radioiodine therapy probably will require re treatment. Hyperthyroidism can be treated medically surgically or with radioactive iodine. This has only been noted in approximately 5 of cases.

Efficacy of low dose 2 millicurie versus standard dose 4 millicurie radioiodine treatment for cats with mild to moderate hyperthyroidism here is one on scintigraphy in general. It is estimated that 10 of cats over ten of cats over the age of ten will develop the disease. Most cats respond to treatment within weeks although some take up to 6 months to gain the full benefit. Most hyperthyroid cats respond fully to a single injection with radio iodine.

Medical treatment consists of administration of methimazole tapazole one to three times a day. Their hyperthyroidism won t come back and they don t need ongoing medication. Radioactive iodine i 131 therapy for feline hyperthyroidism treatment of cats for feline hyperthyroidism with radioactive iodine i 131 is the preferred method of therapy and well as in humans. Serum thyroxine t4 concentrations were measured before treatment in all cats at 12 hour intervals after treatment in 10 cats and at 48 hour intervals after treatment in 21 cats.

The advantages of radioactive iodine therapy are that the procedure most often cures hyperthyroidism has no serious side effects and does not require anesthesia. A single treatment of subcutaneous i 131 cures 95 of cats. Radioactive iodine i 131 therapy is the gold standard therapy for cure of feline hyperthyroidism. It destroys thyroid tumours thereby curing hyperthyroidism.

Radioactive iodine radioiodine or i 131 is used in the treatment of hyperthyroidism which is the most common endocrine hormonal disorder to affect cats. Methimazole treatment will usually control the signs of hyperthyroidism but it is not a cure. Thirty one cats with hyperthyroidism were given one dose of radioactive iodine 131i iv. Under 1 of cats treated with radio iodine will still be hyperthyroid 6 months later.

Radio iodine is the radioactive isotope iodine 131. I 131 is safe and effective. Cats that continue to have low thyroid levels may require thyroid supplementation.
