Our philosophy at the CENTER is to be as thorough and comprehensive as possible. Traditionally, parathyroid surgery was always plagued by not having reliable results because it depended on
This resulted in greater complication rates and inconsistent outcomes.
Parathyroid hormone is cleared from the blood stream very quickly, if the gland stops producing the hormone within five minutes half of the hormone in the blood stream disappears. The rapid intra-operative PTH testing depends on this characteristic of PTH, and measures the level of PTH hormone immediately before starting the surgery and 10 minutes after the abnormal gland is removed. If the level comes down by more than 50%, it is confirmation that the surgery has been successful and the other glands are not over-producing PTH and are normal (this test is 97% accurate). By the end of the procedure the patient will have confirmation that the procedure has been successful.
More then 10% of patients will have more than one hyperactive gland;in these cases, pre-operative localization scans may not identify the additional abnormal glands, because the level of activity may not be high enough to be seen on the Sestamibi scan, and they maybe too small to be seen on ultrasound or CT scan. Therefore, when a surgeon decides to remove just the one parathyroid gland that was identified as abnormal on the localization scans, it is important to have a physiologic way to check that there are no other hyperactive parathyroid glands at the time of surgery. To overcome this problem, once the one gland that is identified as being abnormal is removed, the blood PTH level is tested, if the level does not come down by 50%, it tells the surgeon that there is another abnormal gland that needs to be found and removed. After the other abnormal gland or glands are found and removed the PTH level is tested again to get final confirmation that the surgery has been successful.
