There are several cases in the literature of plasma exchanges done to get levels down for thyroidectomy when agranulocytosis has occurred on antithyroid meds. These recent articles were mainly from European journals but I did find this one from the US.

Sounds rather last ditch, not sure how often it is done here, but hopefully your surgeon has everything lined up to get your surgery done as soon as your levels come down.
