Percutaneous Ultrasound-Guided Laser Ablation with Contrast-Enhanced Ultrasonography for Hyperfunctioning Parathyroid Adenoma: A Preliminary Case Series

Table 2

Tumor volumes, serum parathyroid hormone levels, and serum calcium concentrations before and after laser ablation therapy.

Outcome measure	Before LA	1 day after LA	6 months after LA	12 months after LA
Tumor volume (mL)	0.93 ± 0.58	—	0.53 ± 0.38	0.48 ± 0.34
Serum PTH (pmol/L)	15.23 ± 3.00	7.41 ± 2.79	6.95 ± 1.78	6.90 ± 1.46
Serum calcium (mmol/L)	3.77 ± 0.77	2.50 ± 0.72	2.41 ± 0.37	2.28 ± 0.26

Data are presented as the mean ± standard deviation. LA: laser ablation; PTH: parathyroid hormone; —: not measured. Normal ranges: serum PTH, 0.9–8.2 pmol/L; serum calcium, 2.12–2.60 mmol/L. versus before LA.
