[Diagnostic value of selective parathormone determination in primary hyperparathyroidism]

Area of Science:

• Endocrinology
• Surgical Oncology
• Medical Imaging

Context:

• Parathyroid adenoma localization presents significant surgical challenges, with reported unsuccessful neck exploration rates between 2-18%.
• Anatomical anomalies and small adenoma size contribute to localization difficulties.
• Traditional methods like vital staining, radioisotope scans, and angiography have shown limited accuracy.

Purpose:

• To evaluate the efficacy of fractionized parathyroid hormone measurement via selective venous catheterization for preoperative parathyroid adenoma localization.
• To compare the accuracy of this method against existing localization techniques.

Summary:

• Selective venous catheterization with fractionized parathyroid hormone measurement was employed in 71 patients, achieving correct localization in 77% (47 patients).
• This technique, combined with detailed laboratory diagnosis and monitoring of serum calcium and phosphorus, is presented as a preferred method.
• The study highlights the importance of considering surgical indications cautiously in normocalcemic patients, even with positive localization findings.

Impact:

• Improved preoperative localization accuracy for parathyroid adenomas, potentially reducing surgical complications and re-operations.
• Provides a more reliable diagnostic tool for surgeons dealing with difficult parathyroid adenoma cases.
• Enhances patient management strategies by offering a more precise localization method, guiding surgical intervention effectively.
