O2 therapy was administered. Chest X-Ray was clear he was hospitalised for 24 hours post surgery due to this. We are noting continued coughing retching/gagging and an altered purr and meow sound. He had Dex 24 hours post surgery has been on meloxicom for a week and had convenia injection today.<br />I'm thinking we have a degree of laryngeal paralysis. How long would you expect these symptoms to persist if it was temporary brushing as appose to permenent damage. One thyroid was debulked rather than fully removed and he was due to have this removed in 6 weeks. I am loathe to put him through this again at present . He is due t4 re testing next week.<br />Thank you for any input :-)<br />Anonymoushttps://www.blogger.com/profile/12276688687990866060noreply@blogger.comtag:blogger.com,1999:blog-1407531601642815094.post-30038193967163356992016-01-29T11:06:30.820-05:002016-01-29T11:06:30.820-05:00I would run a TSH level first.

In that case, you wouldn't want to remove the thyroid.Dr. Mark E.

I'd like to ask about my ...Hello Dr Peterson :}<br />I'd like to ask about my patient. <br />It's a 6 Year old male persian cat, his right thyroid gland is slightly enlarged (size of a peanut, the other one has a size of a sunflower seed or even smaller). Gland is enlarging slowly (grown to the peanut size in 20 months since first noticed) but his T4 and fT4 is normal. Should we consider thyroidectomy in this particular patient anyway?<br />I'd be grateful for reply :}Anonymoushttps://www.blogger.com/profile/18258108263737695560noreply@blogger.comtag:blogger.com,1999:blog-1407531601642815094.post-75122043643409275022015-02-26T00:22:52.684-05:002015-02-26T00:22:52.684-05:00After a fair bit of soul searching and expense I h...After a fair bit of soul searching and expense I have just put my cat through a thyroidectomy and was extremely disconcerted to discover she was showing all the restlessness symptoms after the operation that she was not showing at all before it! However I have just read in your blog that cats can show temporary symptoms of hyperthyroidism after the op, which has put my mind at rest a little. I just hope it is only temporary! She's also uncharacteristically very quiet.<br />Thank you for the informative blogAnonymoushttps://www.blogger.com/profile/04611160858605418502noreply@blogger.comtag:blogger.com,1999:blog-1407531601642815094.post-61774518447108910532014-08-05T22:29:57.300-04:002014-08-05T22:29:57.300-04:00Sounds like the recurrent laryngeal nerve may have...Sounds like the recurrent laryngeal nerve may have been damaged.

Hope you can help. He has just starting eating now, I'm hoping he'll get his mew back. Helpful site.

I wish I could answer your question...Good question. I wish I could answer your question but I don't know the answer, at least in cats. <br /><br />I have seen 2 dogs with thyroid tumors in which the serum T4 remained low-normal and the TSH remained high for 4-6 months after thyroidectomy. Unfortunately, I was not able to repeat their thyroid scans but the referring vets (and owners) felt that thyroid replacement was indicated. <br /><br />In human patients, iatrogenic hypothyroidism has also been rarely described after unilateral thyroidectomy.<br /><br />So... it looks like the amount of residual thyroid tissue to maintain euthyroidism is quite variable from patient to patient. Some patients may do fine with only 10% of normal thyroid tissue remaining whereas a few appear to develop hypothyroidism with as much as 50%.<br /><br />Much more work in this area needs to be done, especially in cats. But what else is new!Dr. Mark E.

After that recovery period, however, are all these cats euthyroid?<br /><br />Your blog is more than excellent...thank you!<br />WBIJCShttps://www.blogger.com/profile/16709588772608941230noreply@blogger.com
