The following guidelines should be considered when referring patients to Feline Hyperthyroid Treatment Center for I-131 therapy.
We recommend the following prior to admission (and will provide these services to your client upon your request:
For recently diagnosed cats (never on methimazole:) we need a CBC,Chemistry Panel, T4 and Urinalysis performed within 30 days of treatment.
Although there is no test that rules out masked-renal insufficiency; cats with a urine specific gravity of greater than 1.035 are considered to be excellent candidates for Radioiodine treatment. A methimazole treatment trial is recommended to identify pets with pre-existing renal insufficiency for client communication, although survival times have been shown to be shorter in untreated/ undertreated HT cats with preexisting renal insufficiency [reference will be provided; site is currently under construction/ reference is available immediately upon request.]
For cats on a methimazole trial: we need a T4, CBC, Chemistry Panel and Urinalysis from when the initial diagnosis was made then a recheck Chemistry Panel (minichem is OK) and T4 when the cat is on a therapeutic dose of methimazole. IE - we would like to see how the kidneys respond to a T4 <1.
For cats that have been on medical or dietary management for a period of time, we need a CBC, Chemistry Panel, T4 and a Urinalysis performed within 30 days of treatment.
For all cats we recommend thoracic and abdominal radiographs: This is for staging purposes, a proposed decreased survival time with pulmonary disease, and difficulty treating unrelated problems during the post-treatment quarantine.
We recommended an echocardiogram for cats with a heart murmur. An echocardiogram is required for cats with heart murmur accompanied by arrhythmia or symptoms of CHF as treatment for a cardiac crisis is complicated by isolation protocol.
We require a blood pressure reading (which can be done at admission if desired.) This is to decrease the likelihood of acute severe onset of symptoms of hypertension in cats who are in an increased adrenergic state due to their disease. Even though we take every measure to reduce stress, blood pressure spikes can occur due to stress.
Patients need to be off of oral methimazole for 5 days and off of y/d diet or transdermal methimazole for 30 days prior to admission for I-131 therapy except for patients with significant cardiovascular disease.
We also need current status on patients' vaccination history, including Rabies.
If your patient has pre-existing medical problems, such as cardiovascular/renal disease, please discuss this with our staff. Our patients should be medically stable prior to treatment.
Included in our fee for I-131 treatment are the following:
Case review and evaluation on the day of admission.
A technetium thyroid scan to confirm hyperthyroidism, to rule out thyroid carcinoma and to tailor the dose of I-131 to the needs of the individual patient.
I-131 injection and appropriate radiation monitoring.
The mandatory 2-day hospitalization in our I-131 cat ward (ie- luxury boarding suite.)
Daily patient care.
Daily progress reports for clients.
Client visitation through our large observation window.
30 day post treatment labwork
Follow-up consultations regarding test results between our staff and the referring veterinarian.
Not included in our cost of I-131 treatment are the following:
All necessary diagnostic tests performed at your hospital prior to therapy.
Cardiac or abdominal ultrasound that may be indicated on an individual basis prior to I-131 treatment.
Any emergency care required during hospitalization.
Elective boarding in the I-131 cat ward once the patient has reached safe release level of radioactivity.
T4 level and blood chemistries performed at your hospital post 30 day check up after I-131 therapy.
Please feel free to give our phone number (702) 368-CATS to any of your clients who may be considering the I-131 therapy for their cat. Our staff would be happy to explain our treatment process, fees associated with treatment, the precautions that must be followed for ten days following discharge from our facility and to address any questions or concerns they may have while deciding if I-131 therapy is the best choice for their cat.
