Intraoperative PTH Assay during Minimally Invasive Parathyroidectomy May Be Helpful in the Detection of Double Adenomas and May Minimise the Risk of Recurrent Surgery

Figure 1

Serum PTH concentrations during the Intraoperative period of minimally invasive parathyroidectomy and at follow up, expressed as percentage difference from the baseline value (T0). T0 represents time of sample taken immediately after resection of adenoma and then at every 5 minutes up to 15 minutes (T5, T10, and T15). T0’ represents time of sample taken immediately after resection of a second adenoma and then every 5 minutes for 15 minutes (T5’, T10’, and T15’). Follow up samples were organised after a median (range) of 6 (1–10) months.
