Analysis of central and peripheral PTH decay values in patients with primary hyperparathyroidism.

OBJECTIVE

The aim of this study was to analyze the peculiarities of the collection sites.

METHODS

It is a prospective study of patients undergoing parathyroidectomy by HPTP, with PTH values in the peripheral collection and from the ipsilateral VJI at times: initial (T0) and 10-min after removal of the diseased gland (T10).

RESULTS

61 participants were evaluated. The median PTH at baseline was 147.9 in the peripheral vein and 476.58 in the central vein. The median at T10 was 36 in the peripheral vein and 33 in the central vein. The central vein values showed a greater reduction, with the peripheral values showing a median decay of 74.35%, while the central values dropped by 82.38%. In the initial collection, PTH values were higher in the central vein, while they tended towards homeostasis after the removal of the diseased gland, regardless of the collection site. Thus, the average decay values from the central vein collections were higher and more significant than those from the peripheral veins.

CONCLUSION

The use of central values thus implies greater reliability for to intraoperative monitoring, with long-term comparative studies still being necessary to determine more targeted and effective surgical approaches.
