My platelets were 1094 when I was dx with Essential Thrombocythemia 4 or 5 months ago. I was immediately put on low dose aspirin by the doc, then Hydroxyurea by the specialist. My platelet count is now 608. Under 450 would be ‘normal’, as above, but obviously 608 is a hell of a lot better than over 1000. Symptoms greatly improving but I would be very reluctant to add surgery into the mix, even now. I have read about surgeries being delayed until counts come down. But I guess this decision depends on many factors. Presumably your surgeon is aware of the ET and you can consider pros and cons together.
