Clinical Report: Evaluation of Autologous Parathyroid Graft Viability Post-Endoscopic Thyroidectomy

Overview

This study evaluates the viability of autologous parathyroid grafts after endoscopic thyroidectomy using ultrasound and serum parathyroid hormone (PTH) measurements. Findings indicate significant increases in PTH concentration ratios and specific ultrasonographic features at the graft site.

Background

Hypoparathyroidism is a common complication following thyroidectomy, necessitating strategies to preserve parathyroid function. Autologous parathyroid transplantation has emerged as a technique to mitigate this risk, yet effective assessment of graft viability remains crucial. This study aims to enhance the understanding of graft viability through combined imaging and biochemical methods.

Data Highlights

Key Findings

• 38 patients underwent endoscopic unilateral radical thyroidectomy with autologous parathyroid transplantation.
• PTH concentration on the transplantation side peaked at 3 months postoperatively.
• The PTH ratio remained consistently >1.5-fold after the initial peak.
• Ultrasonography revealed hypoechoic nodules at the graft site with blood flow signals detected by CDFI.
• The study utilized the homogenate injection method for parathyroid transplantation.

Clinical Implications

The combination of ultrasonography and serum PTH measurement provides a method for assessing the viability of transplanted parathyroid glands.

Conclusion

The findings support the use of combined imaging and biochemical assessments for evaluating autologous parathyroid graft viability.
